Chapter IX: Book XI: The Various Kinds of Insects (2)

There is another class also of these insects produced in quite a different manner. These last spring from a grub of larger size, with two horns of very peculiar appearance. The larva then becomes a caterpillar, after which it assumes the state in which it is known as _bombylis_, then that called _necydalus_, and after that, in six months, it becomes a silk-worm.[85] These insects weave webs similar to those of the spider, the material of which is used for making the more costly and luxurious garments of females, known as “bombycina.” Pamphile, a woman of Cos,[86] the daughter of Platea, was the first[87] person who discovered the art of unravelling these webs and spinning a tissue therefrom; indeed, she ought not to be deprived of the glory of having discovered the art of making vestments which, while they cover a woman, at the same moment reveal her naked charms.

CHAP. 27. (23.)—THE SILK-WORM OF COS—HOW THE COAN VESTMENTS ARE MADE.

The silk-worm, too, is said to be a native of the isle of Cos, where the vapours of the earth give new life to the flowers of the cypress, the terebinth, the ash, and the oak which have been beaten down by the showers. At first they assume the appearance of small butterflies with naked bodies, but soon after, being unable to endure the cold, they throw out bristly hairs, and assume quite a thick coat against the winter, by rubbing off the down that covers the leaves, by the aid of the roughness of their feet. This they compress into balls by carding it with their claws, and then draw it out and hang it between the branches of the trees, making it fine by combing it out as it were: last of all, they take and roll it round their body, thus forming a nest in which they are enveloped. It is in this state that they are taken; after which they are placed in earthen vessels in a warm place, and fed upon bran. A peculiar sort of down soon shoots forth upon the body, on being clothed with which they are sent to work upon another task. The cocoons[88] which they have begun to form are rendered soft and pliable by the aid of water, and are then drawn out into threads by means of a spindle made of a reed. Nor, in fact, have the men even felt ashamed to make use[89] of garments formed of this material, in consequence of their extreme lightness in summer: for, so greatly have manners degenerated in our day, that, so far from wearing a cuirass, a garment even is found to be too heavy. The produce of the Assyrian silk-worm, however, we have till now left to the women only.

CHAP. 28. (24.)—SPIDERS; THE KINDS THAT MAKE WEBS; THE MATERIALS USED BY THEM IN SO DOING.

It is by no means an absurdity to append to the silk-worm an account of the spider, a creature which is worthy of our especial admiration. There are numerous kinds of spiders, however, which it will not be necessary here to mention, from the fact of their being so well known. Those that bear the name of _phalangium_ are of small size, with bodies spotted and running to a point; their bite is venomous, and they leap as they move from place to place. Another kind, again, is black, and the fore-legs are remarkable for their length. They have all of them three joints in the legs. The smaller kind of wolf-spider[90] does not make a web, but the larger ones make their holes in the earth, and spread their nets at the narrow entrance thereof. A third kind, again, is remarkable for the skill which it displays in its operations. These spin a large web, and the abdomen suffices to supply the material for so extensive a work, whether it is that, at stated periods the excrements are largely secreted in the abdomen, as Democritus thinks, or that the creature has in itself a certain faculty of secreting[91] a peculiar sort of woolly substance. How steadily does it work with its claws, how beautifully rounded and how equal are the threads as it forms its web, while it employs the weight of its body as an equipoise! It begins at the middle to weave its web, and then extends it by adding the threads in rings around, like a warp upon the woof: forming the meshes at equal intervals, but continually enlarging them as the web increases in breadth, it finally unites them all by an indissoluble knot. With what wondrous art does it conceal the snares that lie in wait for its prey in its checkered nettings! How little, too, would it seem that there is any such trap laid in the compactness of its web and the tenacious texture of the woof, which would appear of itself to be finished and arranged by the exercise of the very highest art! How loose, too, is the body of the web as it yields to the blasts, and how readily does it catch all objects which come in its way! You would fancy that it had left, quite exhausted, the thrums of the upper portion of its net unfinished where they are spread across; it is with the greatest difficulty that they are to be perceived, and yet the moment that an object touches them, like the lines of the hunter’s net, they throw it into the body of the web. With what architectural skill, too, is its hole arched over, and how well defended by a nap of extra thickness against the cold! How carefully, too, it retires into a corner, and appears intent upon anything but what it really is, all the while that it is so carefully shut up from view, that it is impossible to perceive whether there is anything within or not! And then too, how extraordinary the strength of the web! When is the wind ever known to break it, or what accumulation of dust is able to weigh it down?

The spider often spreads its web right across between two trees, when plying its art and learning how to spin; and then, as to its length, the thread extends from the very top of the tree to the ground, while the insect springs up again in an instant from the earth, and travels aloft by the very self-same thread, thus mounting at the same moment and spinning its threads. When its prey falls into its net, how on the alert it is, and with what readiness it runs to seize it! Even though it should be adhering to the very edge of its web, the insect always runs instantly to the middle, as it is by these means that it can most effectually shake the web, and so successfully entangle its prey. When the web is torn, the spider immediately sets about repairing it, and that so neatly, that nothing like patching can ever be seen. The spider lies in wait even for the young of the lizard, and after enveloping the head of the animal, bites its lips; a sight by no means unworthy of the amphitheatre itself, when it is one’s good fortune to witness it. Presages also are drawn from the spider; for when a river is about to swell, it will suspend its web higher than usual. In calm weather these insects do not spin, but when it is cloudy they do, and hence it is, that a great number of cobwebs is a sure sign of showery weather. It is generally supposed that it is the female spider that spins, and the male that lies in wait for prey, thus making an equal division of their duties.

CHAP. 29.—THE GENERATION OF SPIDERS.

Spiders couple[92] backwards, and produce maggots like eggs; for I ought not to defer making some mention of this subject, seeing, in fact, that of most insects there is hardly anything else to be said. All these eggs they lay in their webs, but scattered about, as they leap from place to place while laying them. The phalangium is the only spider that lays a considerable number of them, in a hole; and as soon as ever the progeny is hatched it devours its mother, and very often the male parent as well, for that, too, aids in the process of incubation. These last produce as many as three hundred eggs, the others a smaller number. Spiders take three days to hatch their eggs. They come to their full growth in twenty-eight days.

CHAP. 30. (25.)—SCORPIONS.

In a similar manner to the spider, the land scorpion also produces maggots[93] similar to eggs, and dies in a similar manner. This animal is a dangerous scourge, and has a venom like that of the serpent; with the exception that its effects are far more[94] painful, as the person who is stung will linger for three days before death ensues. The sting is invariably fatal to virgins, and nearly always so to matrons. It is so to men also, in the morning, when the animal has issued from its hole in a fasting state, and has not yet happened to discharge its poison by any accidental stroke. The tail is always ready to strike, and ceases not for an instant to menace, so that no opportunity may possibly be missed. The animal strikes too with a sidelong blow, or else by turning the tail upwards. Apollodorus informs us, that the poison which they secrete is of a white colour, and he has divided them into nine classes, distinguished mostly by their colours—to very little purpose, however, for it is impossible to understand which among these it is that he has pronounced to be the least dangerous. He says, also, that some of them have a double sting, and that the males—for he asserts that they are engendered by the union of the sexes—are the most dangerous. These may easily be known, he says, by their slender form and greater length. He states, also, that they all of them have venom in the middle of the day, when they have been warmed by the heat of the sun, as, also, when they are thirsty—their thirst, indeed, can never be quenched. It is an ascertained fact, that those which have seven joints in the tail are the most[95] deadly; the greater part, however, have but six.

For this pest of Africa, the southern winds have provided means of flight as well, for as the breeze bears them along, they extend their arms and ply them like so many oars in their flight; the same Apollodorus, however, asserts that there are some which really have wings.[96] The Psylli, who for their own profit have been in the habit of importing the poisons of other lands among us, and have thus filled Italy with the pests which belong to other regions, have made attempts to import the flying scorpion as well, but it has been found that it cannot live further north than the latitude of Sicily. However, they[97] are sometimes to be seen in Italy, but are quite harmless there; they are found, also, in many other places, the vicinity of Pharos, in Egypt, for instance. In Scythia, the scorpion is able to kill the swine even with its sting, an animal which, in general, is proof against poisons of this kind in a remarkable degree. When stung, those swine which are black die more speedily than others, and more particularly if they happen to throw themselves into the water. When a person has been stung, it is generally supposed that he may be cured by drinking the ashes of the scorpion[98] mixed with wine. It is the belief also that there is nothing more baneful to the scorpion and the stellio,[99] than to dip them in oil. This last animal is also dangerous to all other creatures, except those which, like itself, are destitute of blood: in figure it strongly resembles the common lizard. For the most part, also, the scorpion does no injury to any animal which is bloodless. Some writers, too, are of opinion that the scorpion devours its offspring, and that the one among the young which is the most adroit avails itself of its sole mode of escape, by placing itself on the back of the mother, and thus finding a place where it is in safety from the tail and the sting. The one that thus escapes, they say, becomes the avenger of the rest, and at last, taking advantage of its elevated position, puts its parents to death. The scorpion produces eleven at a birth.

CHAP. 31. (26.)—THE STELLIO.

The stellio[100] has in some measure the same nature as the chameleon, as it lives upon nothing but dew, and such spiders[101] as it may happen to find.

CHAP. 32.—THE GRASSHOPPER: THAT IT HAS NEITHER MOUTH NOR OUTLET FOR FOOD.

The cicada[102] also lives in a similar manner, and is divided into two kinds. The smaller kind are born the first and die the last, and are without a voice. The others are of the flying kind, and have a note; there are two sorts, those known as _achetæ_, and the smaller ones called _tettigonia_: these last have the loudest voice. In both of these last-mentioned kinds, it is the male that sings, while the female is silent. There are nations in the east that feed upon these insects, the Parthians even, wealthy and affluent as they are. They prefer the male before it has had sexual intercourse, and the female after; and they take[103] their eggs, which are white. They engender with the belly upwards. Upon the back they have a sharp-edged instrument,[104] by means of which they excavate a hole to breed in, in the ground. The young is, at first, a small maggot in appearance, after which the larva assumes the form in which it is known as the _tettigometra_.[105] It bursts its shell about the time of the summer solstice, and then takes to flight, which always happens in the night. The insect, at first, is black and hard.

This is the only living creature that has no mouth; though it has something instead which bears a strong resemblance to the tongues of those insects which carry a sting in the mouth: this organ is situate in the breast[106] of the animal, and is employed by it in sucking up the dew. The corselet itself forms a kind of pipe; and it is by means of this that the achetæ utter their note, as already mentioned. Beyond this, they have no viscera in the abdomen. When surprised, they spring upwards, and eject a kind of liquid, which, indeed, is our only proof that they live upon dew. This, also, is the only animal that has no outlet for the evacuations of the body. Their powers of sight are so bad, that if a person contracts his finger, and then suddenly extends it close to them, they will come upon it just as though it were a leaf. Some authors divide these animals into two kinds, the “surcularia,”[107] which is the largest, and the “frumentaria,”[108] by many known as the “avenaria;”[109] this last makes its appearance just as the corn is turning dry in the ear.

(27.) The grasshopper is not a native of countries that are bare of trees—hence it is that there are none in the vicinity of the city of Cyrene—nor, in fact, is it produced in champaign countries, or in cool and shady thickets. They will take to some places much more readily than others. In the district of Miletus they are only to be found in some few spots; and in Cephallenia, there is a river which runs through the country, on one side of which they are not to be found, while on the other they exist in vast numbers. In the territory of Rhegium, again, none of the grasshoppers have any note, while beyond the river, in the territory of Locri,[110] they sing aloud. Their wings are formed similarly to those of bees, but are larger, in proportion to the body.

CHAP. 33. (28.)—THE WINGS OF INSECTS.[111]

There are some insects which have two wings, flies, for instance; others, again, have four, like the bee. The wings of the grasshopper are membranous. Those insects which are armed with a sting in the abdomen, have four wings. None of those which have a sting in the mouth, have more than two wings. The former have received the sting for the purpose of defending themselves, the latter for the supplying of their wants. If pulled from off the body, the wings of an insect will not grow again; no insect which has a sting inserted in its body, has two wings only.

CHAP. 34.—THE BEETLE. THE GLOW-WORM. OTHER KINDS OF BEETLES.

Some insects, for the preservation of their wings, are covered with a crust;[112] the beetle, for instance, the wing of which is peculiarly fine and frail. To these insects a sting has been denied by Nature; but in one large kind[113] we find horns of a remarkable length, two-pronged at the extremities, and forming pincers, which the animal closes when it is its intention to bite. These beetles are suspended from the neck of infants by way of remedy against certain maladies: Nigidius calls them “lucani.” There is another kind[114] of beetle, again, which, as it goes backwards with its feet, rolls the dung into large pellets, and then deposits in them the maggots which form its young, as in a sort of nest, to protect them against the rigours of winter. Some, again, fly with a loud buzzing or a drony noise, while others[115] burrow numerous holes in the hearths and out in the fields, and their shrill chirrup is to be heard at night.

The glow-worm, by the aid of the colour of its sides[116] and haunches, sends forth at night a light which resembles that of fire; being resplendent, at one moment, as it expands its wings,[117] and then thrown into the shade the instant it has shut them. These insects are never to be seen before the grass of the pastures has come to maturity, nor yet after the hay has been cut. On the other hand, it is the nature of the black beetle[118] to seek dark corners, and to avoid the light: it is mostly found in baths, being produced from the humid vapours which arise therefrom. There are some beetles also, belonging to the same species, of a golden colour and very large size, which burrow[119] in dry ground, and construct small combs of a porous nature, and very like sponge; these they fill with a poisonous kind of honey. In Thrace, near Olynthus, there is a small locality, the only one in which this animal cannot exist; from which circumstance it has received the name of “Cantharolethus.”[120]

The wings of all insects are formed without[121] any division in them, and they none of them have a tail,[122] with the exception of the scorpion; this, too, is the only one among them that has arms,[123] together with a sting in the tail. As to the rest of the insects, some of them have the sting in the mouth, the gad-fly for instance, or the “tabanus,” as some persons choose to call it: the same is the case, too, with the gnat and some kinds of flies. All these insects have their stings situate in the mouth instead[124] of a tongue; but in some the sting is not pointed, being formed not for pricking, but for the purpose of suction: this is the case more especially with flies, in which it is clear that the tongue[125] is nothing more than a tube. These insects, too, have no teeth. Others, again, have little horns protruding in front of the eyes, but without any power in them; the butterfly, for instance. Some insects are destitute of wings, such as the scolopendra, for instance.[126]

CHAP. 35.—LOCUSTS.

Those insects which have feet, move sideways. Some of them have the hind feet longer than the fore ones, and curving outwards, the locust, for example.

(29.) These creatures lay their eggs in large masses, in the autumn, thrusting the end of the tail into holes which they form in the ground. These eggs remain underground throughout the winter, and in the ensuing year, at the close of spring, small locusts issue from them, of a black colour, and crawling along without legs[127] and wings. Hence it is that a wet spring destroys their eggs, while, if it is dry, they multiply in great abundance. Some persons maintain that they breed twice a year, and die the same number of times; that they bring forth at the rising[128] of the Vergiliæ, and die at the rising of the Dog-star,[129] after which others spring up in their places: according to some, it is at the setting[130] of Arcturus that the second litter is produced. That the mothers die the moment they have brought forth, is a well-known fact, for a little worm immediately grows about the throat, which chokes them: at the same time, too, the males perish as well. This insect, which thus dies through a cause apparently so trifling, is able to kill a serpent by itself, when it pleases, by seizing its jaws with its teeth.[131] Locusts are only produced in champaign places, that are full of chinks and crannies. In India, it is said that they attain the length of three[132] feet, and that the people dry the legs and thighs, and use them for saws. There is another mode, also, in which these creatures perish; the winds carry them off in vast swarms, upon which they fall into the sea or standing waters, and not, as the ancients supposed, because their wings have been drenched by the dampness of the night. The same authors have also stated, that they are unable to fly during the night, in consequence of the cold, being ignorant of the fact, that they travel over lengthened tracts of sea for many days together, a thing the more to be wondered at, as they have to endure hunger all the time as well, for this it is which causes them to be thus seeking pastures in other lands. This is looked upon as a plague[133] inflicted by the anger of the gods; for as they fly they appear to be larger than they really are, while they make such a loud noise with their wings, that they might be readily supposed to be winged creatures of quite another species. Their numbers, too, are so vast, that they quite darken the sun; while the people below are anxiously following them with the eye, to see if they are about to make a descent, and so cover their lands. After all, they have the requisite energies for their flight; and, as though it had been but a trifling matter to pass over the seas, they cross immense tracts of country, and cover them in clouds which bode destruction to the harvests. Scorching numerous objects by their very contact, they eat away everything with their teeth, the very doors of the houses even.

Those from Africa are the ones which chiefly devastate Italy; and more than once the Roman people have been obliged to have recourse to the Sibylline Books, to learn what remedies to employ under their existing apprehensions of impending famine. In the territory of Cyrenaica[134] there is a law, which even compels the people to make war, three times a year, against the locusts, first, by crushing their eggs, next by killing the young, and last of all by killing those of full growth; and he who fails to do so, incurs the penalty of being treated as a deserter. In the island of Lemnos also, there is a certain measure fixed by law, which each individual is bound to fill with locusts which he has killed, and then bring it to the magistrates. It is for this reason, too, that they pay such respect to the jack-daw, which flies to meet the locusts, and kills them in great numbers. In Syria, also, the people are placed under martial law, and compelled to kill them: in so many countries does this dreadful pest prevail. The Parthians look upon them as a choice food,[135] and the grasshopper as well. The voice of the locust appears to proceed from the back part of the head. It is generally believed that in this place, where the shoulders join on to the body, they have, as it were, a kind of teeth, and that it is by grinding these against each other that they produce the harsh noise which they make. It is more especially about the two equinoxes that they are to be heard, in the same way that we hear the chirrup of the grasshopper about the summer solstice. The coupling of locusts is similar to that of all other insects that couple, the female supporting the male, and turning back the extremity of the tail towards him; it is only after a considerable time that they separate. In all these kinds of insects the male is of smaller size than the female.

CHAP. 36. (30.)—ANTS.

The greater part of the insects produce a maggot. Ants also produce one in spring, which is similar to an egg,[136] and they work in common, like bees; but whereas the last make their food, the former only store[137] it away. If a person only compares the burdens which the ants carry with the size of their bodies, he must confess that there is no animal which, in proportion, is possessed of a greater degree of strength. These burdens they carry with the mouth, but when it is too large to admit of that, they turn their backs to it, and push it onwards with their feet, while they use their utmost energies with their shoulders. These insects, also, have a political community among themselves, and are possessed of both memory and foresight. They gnaw each grain before they lay it by, for fear lest it should shoot while under ground; those grains, again, which are too large for admission, they divide at the entrance of their holes; and those which have become soaked by the rain, they bring out and dry.[138] They work, too, by night, during the full moon; but when there is no moon, they cease working. And then, too, in their labours, what ardour they display, what wondrous carefulness! Because they collect their stores from different quarters, in ignorance of the proceedings of one another, they have certain days set apart for holding a kind of market, on which they meet together and take stock.[139] What vast throngs are then to be seen hurrying together, what anxious enquiries appear to be made, and what earnest parleys[140] are going on among them as they meet! We see even the very stones worn away by their footsteps, and roads beaten down by being the scene of their labours. Let no one be in doubt, then, how much assiduity and application, even in the very humblest of objects, can upon every occasion effect! Ants are the only living beings, besides man, that bestow burial on the dead. In Sicily there are no winged ants to be found.

(31.) The horns of an Indian ant, suspended in the temple of Hercules, at Erythræ,[141] have been looked upon as quite miraculous for their size. This ant excavates gold from holes, in a country in the north of India, the inhabitants of which are known as the Dardæ. It has the colour of a cat, and is in size as large as an Egyptian wolf.[142] This gold, which it extracts in the winter, is taken by the Indians during the heats of summer, while the ants are compelled, by the excessive warmth, to hide themselves in their holes. Still, however, on being aroused by catching the scent of the Indians, they sally forth, and frequently tear them to pieces, though provided with the swiftest camels for the purpose of flight; so great is their fleetness, combined with their ferocity and their passion for gold!

CHAP. 37. (32.)—THE CHRYSALIS.

Many insects, however, are engendered in a different manner; and some more especially from dew. This dew settles upon the radish[143] leaf in the early days of spring; but when it has been thickened by the action of the sun, it becomes reduced to the size of a grain of millet. From this a small grub afterwards arises, which, at the end of three days, becomes transformed into a caterpillar. For several successive days it still increases in size, but remains motionless, and covered with a hard husk. It moves only when touched, and is covered with a web like that of the spider. In this state it is called a chrysalis, but after the husk is broken, it flies forth in the shape of a butterfly.

CHAP. 38. (33.)—ANIMALS WHICH BREED IN WOOD.

In the same manner, also, some animals are generated in the earth from rain, and some, again, in wood. And not only wood-worms[144] are produced in wood, but gad-flies also and other insects issue from it, whenever there is an excess of moisture; just as in man, tape-worms[145] are sometimes found, as much as three hundred feet or more in length.

CHAP. 39.—INSECTS THAT ARE PARASITES OF MAN. WHICH IS THE SMALLEST OF ANIMALS? ANIMALS FOUND IN WAX EVEN.

Then, too, in dead carrion there are certain animals produced, and in the hair, too, of living men. It was through such vermin as this that the Dictator Sylla,[146] and Alcman, one of the most famous of the Grecian poets, met their deaths. These insects infest birds too, and are apt to kill the pheasant, unless it takes care to bathe itself in the dust. Of the animals that are covered with hair, it is supposed that the ass and the sheep are the only ones that are exempt from these vermin. They are produced, also, in certain kinds of cloth, and more particularly those made of the wool of sheep which have been killed by the wolf. I find it stated, also, by authors, that some kinds of water[147] which we use for bathing are more productive of these parasites than others. Even wax is found to produce mites, which are supposed to be the very smallest of all living creatures. Other insects, again, are engendered from filth, acted upon by the rays of the sun—these fleas are called “petauristæ,”[148] from the activity which they display in their hind legs. Others, again, are produced with wings, from the moist dust that is found lying in holes and corners.

CHAP. 40. (34.)—AN ANIMAL WHICH HAS NO PASSAGE FOR THE EVACUATIONS.

There is an animal,[149] also, that is generated in the summer, which has its head always buried deep in the skin [of a beast], and so, living on its blood, swells to a large size. This is the only living creature that has no outlet[150] for its food; hence, when it has overgorged itself, it bursts asunder, and thus its very aliment is made the cause of its death. This insect never breeds on beasts of burden, but is very commonly seen on oxen, and sometimes on dogs, which, indeed, are subject to every species of vermin. With sheep and goats, it is the only parasite. The thirst, too, for blood displayed by leeches, which we find in marshy waters, is no less singular; for these will thrust the entire head into the flesh in quest of it. There is a winged insect[151] which peculiarly infests dogs, and more especially attacks them with its sting about the ears, where they are unable to defend themselves with their teeth.

CHAP. 41. (35.)—MOTHS, CANTHARIDES, GNATS—AN INSECT THAT BREEDS IN THE SNOW.

Dust, too, is productive of worms[152] in wools and cloths, and this more especially if a spider should happen to be enclosed in them: for, being sensible of thirst, it sucks up all the moisture, and thereby increases the dryness of the material. These will breed in paper also. There is one kind which carries with it its husk, in the same manner as the snail, only that the feet are to be seen. If deprived of it, it does not survive; and when it is fully developed, the insect becomes a chrysalis. The wild fig-tree produces gnats,[153] known as “ficarii;” and the little grubs of the fig-tree, the pear-tree, the pine, the wild rose, and the common rose produce cantharides,[154] when fully developed. These insects, which are venomous, carry with them their antidote; for their wings are useful in medicine,[155] while the rest of the body is deadly. Again, liquids turned sour will produce other kinds of gnats, and white grubs are to be found in snow that has lain long on the ground, while those that lie above are of a reddish[156] colour—indeed, the snow itself becomes red after it has lain some time on the ground. These grubs are covered with a sort of hair, are of a rather large size, and in a state of torpor.

CHAP. 42. (36.)—AN ANIMAL FOUND IN FIRE—THE PYRALLIS OR PYRAUSTA.

That element, also, which is so destructive to matter, produces certain animals; for in the copper-smelting furnaces of Cyprus, in the very midst of the fire, there is to be seen flying about a four-footed animal with wings, the size of a large fly: this creature is called the “pyrallis,” and by some the “pyrausta.” So long as it remains in the fire it will live, but if it comes out and flies a little distance from it, it will instantly die.

CHAP. 43.—THE ANIMAL CALLED HEMEROBION.

The Hypanis, a river of Pontus, brings down in its waters, about the time of the summer solstice, small membranous particles, like a grape-stone in appearance; from which there issues an animal[157] with four legs and with wings, similar to the one just mentioned. It does not, however, live more than a single day, from which circumstance it has obtained the name of “hemerobion.”[158] The life of other insects of a similar nature is regulated from its beginning to its end by multiples of seven. Thrice seven days is the duration of the life of the gnat and of the maggot, while those that are viviparous live four times seven days, and their various changes and transformations take place in periods of three or four days. The other insects of this kind that are winged, generally die in the autumn, the gad-fly becoming quite blind[159] even before it dies. Flies which have been drowned in water, if they are covered with ashes,[160] will return to life.

CHAP. 44. (37.)—THE NATURE AND CHARACTERISTICS OF ALL ANIMALS CONSIDERED LIMB BY LIMB. THOSE WHICH HAVE TUFTS AND CRESTS.

In addition to what is already stated, we will add an account of every part of the body of an animal, taken limb by limb.

All those which have blood, have a head as well. A small number of animals, and those only among the birds, have tufts of various kinds upon the head. The phœnix[161] has a long row of feathers on it, from the middle of which arises another row; peacocks have a hairy tuft, resembling a bushy shrub; the stymphalis[162] has a sort of pointed crest, and the pheasant, again, small horns. Added to these, there is the lark, a little bird, which, from the appearance of its tuft, was formerly called “galerita,” but has since received the Gallic name of “alauda,”[163] a name which it has transferred to one of our legions.[164] We have already made mention, also, of one bird[165] to which Nature has given a crest, which it can fold or unfold at pleasure: the birds of the coot kind[166] have also received from her a crest, which takes its rise at the beak, and runs along the middle of the head; while the pie of Mars, and the Balearic crane, are furnished with pointed tufts. But the most remarkable feature of all, is the crest which we see attached to the heads of our domestic fowls, substantial and indented like a saw; we cannot, in fact, strictly call it flesh, nor can we pronounce it to be cartilage or a callosity, but must admit that it is something of a nature peculiar to itself. As to the crests of dragons, there is no one to be found who ever saw one.

CHAP. 45.—THE VARIOUS KINDS OF HORNS. ANIMALS IN WHICH THEY ARE MOVEABLE.

Horns, too, of various forms have been granted to many animals of the aquatic, marine, and reptile kind, but those which are more properly understood under that name belong to the quadrupeds only; for I look upon the tales of Actæon and of Cippus even, in Latin story, as nothing more nor less than fables.[167] And, indeed, in no department of her works has Nature displayed a greater capriciousness. In providing animals with these weapons, she has made merry at their expense; for some she has spread them out in branches, the stag, for instance; to others she has given them in a more simple form, as in the “subulo,” so called from the resemblance of its horns to a “subula,”[168] or shoemaker’s awl. In others, again, she has flattened them in the shape of a man’s hand, with the fingers extended, from which circumstance the animal has received the name of “platyceros.”[169] To the roe-buck she has given branching horns, but small, and has made them so as not to fall off and be cast each year; while to the ram she has given them of a contorted and spiral form, as though she were providing it with a cæstus for offence. The horns of the bull, again, are upright and threatening. In this last kind, the females, too, are provided with them, while in most it is only the males. The chamois has them, curving backwards; while in the fallow deer[170] they bend forward. The strepsiceros,[171] which in Africa bears the name of addax, has horns erect and spiral, grooved and tapering to a sharp point, so much so, that you would almost take them to be the sides of a lyre.[172] In the oxen of Phrygia, the horns are moveable,[173] like the ears; and among the cattle of the Troglodytæ, they are pointed downwards to the ground, for which reason it is that they are obliged to feed with the head on one side. Other animals, again, have a single horn, and that situate in the middle of the head, or else on the nose, as already stated.[174]

Then, again, in some animals the horns are adapted for butting, and in others for goring; with some they are curved inwards, with others outwards, and with others, again, they are fitted for tossing: all which objects are effected in various ways, the horns either lying backwards, turning from, or else towards each other, and in all cases running to a sharp point. In one kind, also, the horns are used for the purpose of scratching the body, instead of hands.

In snails the horns are fleshy, and are thus adapted for the purpose of feeling the way, which is also the case with the cerastes;[175] some reptiles, again, have only one horn, though the snail has always two, suited for protruding and withdrawing. The barbarous nations of the north drink from the horns of the urus,[176] a pair of which will hold a couple of urnæ:[177] other tribes, again, point their spears with them. With us they are cut into laminæ, upon which they become transparent; indeed, the rays of a light placed within them may be seen to a much greater distance than without. They are used also for various appliances of luxury, either coloured or varnished, or else for those kinds of paintings which are known as “cestrota,”[178] or horn-pictures. The horns of all animals are hollow within, it being only at the tip that they are solid: the only exception is the stag, the horn of which is solid throughout, and is cast every year. When the hoofs of oxen are worn to the quick, the husbandmen have a method of curing them, by anointing the horns of the animal with grease. The substance of the horns is so ductile, that even while upon the body of the living animal, they can be bent by being steeped in boiling wax, and if they are split down when they are first shooting, they may be twisted different ways, and so appear to be four in number upon one head. In females the horns are generally thinner than in the males, as is the case, also, with most kinds of wool-bearing animals.

No individuals, however, among sheep, or hinds, nor yet any that have the feet divided into toes, or that have solid hoofs, are furnished with horns; with the sole exception of the Indian ass,[179] which is armed with a single horn. To the beasts that are cloven-footed Nature has granted two horns, but to those that have fore-teeth in the upper jaw, she has given none. Those persons who entertain the notion that the substance of these teeth is expended in the formation of the horns, are easily to be refuted, if we only consider the case of the hind, which has no more teeth than the male, and yet is without horns altogether. In the stag the horn is only imbedded in the skin, but in the other[180] animals it adheres to the bone.

CHAP. 46.—THE HEADS OF ANIMALS. THOSE WHICH HAVE NONE.

The head of the fish is very large in proportion to the rest of the body, probably, to facilitate its diving under water. Animals of the oyster and the sponge kind have no head, which is the case, also, with most of the other kinds, whose only sense is that of touch. Some, again, have the head blended with the body, the crab, for instance.

CHAP. 47.—THE HAIR.

Of all animals man has the longest hair upon the head; which is the case more especially with those nations where the men and women in common leave the hair to grow, and do not cut it. Indeed, it is from this fact, that the inhabitants of the Alps have obtained from us the name of “Capillati,”[181] as also those of Gallia, “Comata.”[182] There is, however, a great difference in this respect according to the various countries. In the island of Myconus,[183] the people are born without hair, just as at Caunus the inhabitants are afflicted with the spleen from their birth.[184] There are some animals, also, that are naturally bald, such as the ostrich, for instance, and the aquatic raven, which last has thence derived its Greek[185] name. It is but rarely that the hair falls off in women, and in eunuchs such is never known to be the case; nor yet does any person lose it before having known sexual intercourse.[186] The hair does not fall off below the brain, nor yet beneath the crown of the head, or around the ears and the temples. Man is the only animal that becomes bald, with the exception, of course, of such animals as are naturally so. Man and the horse are the only creatures whose hair turns grey; but with man this is always the case, first in the fore-part of the head, and then in the hinder part.

CHAP. 48.—THE BONES OF THE HEAD.

Some few persons only are double-crowned. The bones of the head are flat, thin, devoid of marrow, and united with sutures indented like a comb. When broken asunder they cannot be united, but the extraction of a small portion is not necessarily fatal, as a fleshy cicatrix forms, and so makes good the loss. We have already mentioned, in their respective[187] places, that the skull of the bear is the weakest of all, and that of the parrot the hardest.

CHAP. 49.—THE BRAIN.

The brain exists in all animals which have blood, and in those sea animals as well, which we have already mentioned as mollusks, although they are destitute of blood, the polypus, for instance. Man, however, has, in proportion to his body, the most voluminous brain of all. This, too, is the most humid, and the coldest of all the viscera, and is enveloped above and below with two membranous integuments, for either of which to be broken is fatal. In addition to these facts, we may remark that the brain is larger in men than in women. In man the brain is destitute of blood and veins, and in other animals it has no fat. Those who are well informed on the subject, tell us that the brain is quite a different substance from the marrow, seeing that on being boiled it only becomes harder. In the very middle of the brain of every animal there are small bones found. Man is the only animal in which it is known to palpitate[188] during infancy; and it does not gain its proper consistency until after the child has made its first attempt to speak. The brain is the most elevated of all the viscera, and the nearest to the roof of the head; it is equally devoid of flesh, blood, and excretions. The senses hold this organ as their citadel; it is in this that are centred all the veins which spring from the heart; it is here that they terminate; this is the very culminating point of all, the regulator of the understanding. With all animals it is advanced to the fore-part of the head, from the fact that the senses have a tendency to the direction in which we look. From the brain proceeds sleep, and its return it is that causes the head to nod. Those creatures, in fact, which have no brain, never sleep. It is said that stags[189] have in the head certain small maggots, twenty in number: they are situate in the empty space that lies beneath the tongue, and around the joints by which the head is united to the body.

CHAP. 50.—THE EARS. ANIMALS WHICH HEAR WITHOUT EARS OR APERTURES.

Man is the only animal the ears of which are immoveable. It is from the natural flaccidity of the ear, that the surname of _Flaccus_ is derived. There is no part of the body that creates a more enormous expense for our women, in the pearls which are suspended from them. In the East, too, it is thought highly becoming for the men, even, to wear gold rings in their ears. Some animals have large, and others small ears. The stag alone has them cut and divided, as it were; in the field-mouse they have a velvet surface. All the animals that are viviparous have ears of some kind or other, with the sole exception of the sea-calf, the dolphin, the fishes which we have mentioned[190] as cartilaginous, and the viper. These animals have only cavities instead of ears, with the exception of the cartilaginous fishes and the dolphin, which last, however, it is quite clear possesses the sense of hearing, for it is charmed by singing, and is often taken while enraptured with the melody: how it is that it does hear, is quite marvellous. These animals, too, have not the slightest trace of olfactory organs, and yet they have a most acute sense of smell.

Among the winged animals, only the horned owl and the long-eared owl have feathers which project like ears, the rest having only cavities for the purpose of hearing; the same is the case, also, with the scaly animals and the serpents. Among horses and beasts of burden of all kinds, it is the ears which indicate the natural feelings; when the animal is weary, they are drooping and flaccid; when it is startled, they quiver to and fro; when it is enraged, they are pricked up; and when it is ailing, they are pendant.

CHAP. 51.—THE FACE, THE FOREHEAD, AND THE EYE-BROWS.

Man is the only creature that has a face, the other animals having only a muzzle or a beak. Other animals have a forehead as well, but it is only on the forehead of man that is depicted sorrow, gladness, compassion, or severity. It is the forehead that is the index of the mind. Man has eyebrows, also, which move together or alternately; these, too, serve in some measure as indications of the feelings. Do we deny or do we assent, it is the eyebrows, mostly, that indicate our intentions. Feelings of pride may be generated elsewhere, but it is here that they have their principal abode; it is in the heart that they take their rise, but it is to the eyebrows that they mount, and here they take up their position. In no part of the body could they meet with a spot more lofty and more precipitous, in which to establish themselves free from all control.

CHAP. 52.—THE EYES—ANIMALS WHICH HAVE NO EYES, OR HAVE ONLY ONE EYE.

Below the forehead are the eyes, which form the most precious portion of the human body, and which, by the enjoyment of the blessings of sight, distinguish life from death. Eyes, however, have not been granted to all animals; oysters have none, but, with reference to some of the shell-fish, the question is still doubtful; for if we move the fingers before a scallop half open, it will immediately close its shell, apparently from seeing them, while the solen[191] will start away from an iron instrument when placed near it. Among quadrupeds the mole[192] has no sight, though it has something that bears a resemblance to eyes, if we remove the membrane that is extended in front of them. Among birds also, it is said that a species of heron, which is known as the “leucus,”[193] is wanting of one eye: a bird of most excellent augury, when it flies towards the south or north, for it is said that it portends thereby that there is about to be an end of perils and alarms. Nigidius says also, that neither locusts nor grasshoppers have eyes. In snails,[194] the two small horns with which they feel their way, perform the duties of eyes. Neither the mawworm[195] nor any other kind of worm has eyes.

CHAP. 53.—THE DIVERSITY OF THE COLOUR OF THE EYES.

The eyes vary in colour in the human race only; in all other animals they are of one uniform colour peculiar to the kind, though there are some horses that have eyes of an azure colour. But in man the varieties and diversities are most numerous; the eyes being either large, of middling size, remarkably small, or remarkably prominent. These last are generally supposed to be very weak, while those which are deep-seated are considered the best, as is the case also with those which in colour resemble the eyes of the goat.

CHAP. 54.—THE THEORY OF SIGHT—PERSONS WHO CAN SEE BY NIGHT.

In addition to this, there are some persons who can see to a very great distance, while there are others, again, who can only distinguish objects when brought quite close to them. The vision of many stands in need of the rays of the sun; such persons cannot see on a cloudy day, nor yet after the sun has set. Others, again, have bad sight in the day-time, but a sight superior to that of others by night. Of persons having double pupils, or the evil eye, we have already spoken[196] at sufficient length. Blue[197] eyes are the best for seeing in the dark.

It is said that Tiberius Cæsar, like no other human being, was so endowed by Nature, that on awaking in the night[198] he could for a few moments distinguish objects just as well as in the clearest daylight, but that by degrees he would find his sight again enveloped in darkness. The late Emperor Augustus had azure eyes like those of some horses, the white being larger than with other men; he used to be very angry if a person stared intently at them for this peculiarity. Claudius Cæsar had at the corners of the eyes a white fleshy substance, covered with veins, which would occasionally become suffused with blood; with the Emperor Caius[199] they had a fixed, steady gaze, while Nero could see nothing distinctly without winking, and having it brought close to his eyes. The Emperor Caius had twenty pairs of gladiators in his training-school, and of all these there were only two who did not wink the eyes when a menacing gesture was made close to them: hence it was that these men were invincible. So difficult a matter is it for a man to keep his eyes from winking: indeed, to wink is so natural to many, that they cannot desist from it; such persons we generally look upon as the most timid.
