The year 1800 begins a new Cycle.
[Sidenote: _Easter_ Cycle, deficient.]
425. The _Cycle of Easter_, also called the _Dionysian Period_, is a revolution of 532 years, found by multiplying the Solar Cycle 28 by the Lunar Cycle 19. If the New Moons did not anticipate upon this Cycle, _Easter-Day_ would always be the _Sunday_ next after the first Full Moon which succeeds the 21st of _March_. But, on account of the above anticipation § 422, to which no proper regard was had before the late alteration of the _Style_, the _Ecclesiastic Easter_ has several times been a week different from the _true Easter_ within this last Century: which inconvenience is now remedied by making the Table which used to find Easter _for ever_, in the Common Prayer Book, of no longer use than the Lunar difference from the _New Style_ will admit of.
[Sidenote: Number of Direction.
To find the true _Easter_.]
426. The _earliest Easter possible_ is the 22d of _March_, the _latest_ the 25th of _April_. Within these limits are 35 days, and the number belonging to each of them is called the _Number of Direction_; because thereby the time of Easter is found for any given year. To find the Number of Direction, according to the _New Style_, enter Table V following this Chapter, with the compleat hundreds of any given year at the top, and the years thereof (if any) below an hundred at the left hand; and where the columns meet is the Dominical Letter for the given year. Then, enter Table I, with the compleat hundreds of the same year at the left hand, and the years below an hundred at the top; and where the columns meet is the Golden Number for the same year. Lastly, enter Table II with the Dominical Letter at the left hand and Golden Number at the top; and where the columns meet is the Number of Direction for that year; which number, added to the 21st day of _March_ shews on what day either of _March_ or _April_ Easter _Sunday_ falls in that year. Thus, the Dominical Letter _New Style_ for the year 1757 is _B_ (Table V) and the Golden Number is 10, (Table I) by which in Table II, the Number of Direction is found to be 20; which, reckoned from the 21st of _March_, ends on the 10th of _April_, and _that_ is _Easter Sunday_ in the year 1757. _N. B._ There are always two Dominical Letters to the leap-year, the first of which takes place to the 24th of _February_, the last for the following part of the year.
[Sidenote: Dominical Letter.]
427. _The first seven Letters of the Alphabet_ are commonly placed in the annual Almanacks to shew on what days of the week the days of the months fall throughout the year. And because one of those seven Letters must necessarily stand against _Sunday_ it is printed in a capital form, and called the _Dominical Letter_: the other six being inserted in small characters to denote the other six days of the week. Now, since a common _Julian Year_ contains 365 Days, if this number be divided by 7 (the number of days in a week) there will remain one day. If there had been no remainder, ’tis plain the year would constantly begin on the same day of the week. But since one remains, ’tis as plain that the year must begin and end on the same day of the week; and therefore the next year will begin on the day following. Hence, when _January_ begins on _Sunday_, _A_ is the Dominical or _Sunday_ Letter for that year: then, because the next year begins on _Monday_, the _Sunday_ will fall on the seventh day, to which is annexed the seventh Letter _G_, which therefore will be the Dominical Letter for all that year: and as the third year will begin on _Tuesday_, the _Sunday_ will fall on the sixth day; therefore _F_ will be the _Sunday_ Letter for that year. Whence ’tis evident that the _Sunday_ Letters will go annually in a retrograde order thus, _G_, _F_, _E_, _D_, _C_, _B_, _A_. And in the course of seven years, if they were all common ones, the same days of the week and Dominical Letters would return to the same days of the months. But because there are 366 days in a leap-year, if this number be divided by 7, there will remain two days over and above the 52 weeks of which the year consists. And therefore, if the leap-year begins on _Sunday_, it will end on _Monday_; and the next year will begin on _Tuesday_, the first _Sunday_ whereof must fall on the sixth of _January_, to which is annexed the Letter _F_, and not _G_ as in common years. By this means, the leap-year returning every fourth year, the order of the Dominical Letters is interrupted; and the Series does not return to its first state till after four times seven, or 28 years: and then the same days of the month return in order to the same days of the week.
[Sidenote: To find the Dominical Letter.]
428. _To find the Dominical Letter for any year either before or after the Christian Æra_[87]: In Table III or IV for _Old Style_, or V for _New Style_, look for the hundreds of years at the head of the Table, and for the years below an hundred (to make up the given year) at the left hand: and where the columns meet you have the Dominical Letter for the year desired. Thus, suppose the Dominical Letter be required for the year of CHRIST 1758, _New Style_, I look for 1700 at the head of Table V, and for 58 at the left hand of the same Table; and in the angle of meeting, I find _A_, which is the Dominical Letter for that year. If it was wanted for the same year _Old Style_, it would be found by Table IV to be _D_. But _to find the Dominical Letter for any given year before_ CHRIST, subtract one from _that_ year and then proceed in all respects as just now taught, to find it by Table III Thus, suppose the Dominical Letter be required for the 585th year before the first year of CHRIST, look for 500 at the head of Table III, and for 84 at the left hand; in the meeting of these columns is _FE_, which were the Dominical Letters for that year, and shews that it was a leap-year; because, leap-year has always two Dominical Letters.
[Sidenote: To find the Days of the Months.]
429. _To find the day of the month answering to any day of the week, or the day of the week answering to any day of the month; for any year past or to come:_ Having found the Dominical Letter for the given year, enter Table VI, with the Dominical Letter at the head; and under it, all the days in that column to the right hand are _Sundays_, in the divisions of the months; the next column to the right are _Mondays_; the next, _Tuesdays_; and so on to the last column under _G_, from which go back to the column under _A_, and thence proceed towards the right hand as before. Thus, in the year 1757, the Dominical Letter _New Style_ is _B_, in Table V, then in Table VI all the days under _B_ are _Sundays_ in that year, _viz._ the 2d, 9th, 16th, 23d, and 30th of _January_ and _October_; the 6th, 13th, 20th, and 27th of _February_, _March_ and _November_; the 3d, 10th, and 17th, of _April_ and _July_, together with the 31st of _July_: and so on to the foot of the column. Then, of course, all the days under _C_ on _Mondays_, namely the 3d, 10th, _&c._ of _January_ and _October_; and so of all the rest in that column. If _the day of the week answering to any day of the month_ be required, it is easily had from the same Table by the Letter that stands at the top of the column in which the given day of the month is found. Thus, the Letter that stands over the 28th of _May_ is _A_; and in the year 585 before CHRIST the Dominical Letter was found to be _FE_ § 428; which being a leap-year, and _E_ taking place from the 24th of _February_ to the end of that year, shews by the Table that the 25th of _May_ was on a _Sunday_; and therefore the 28th must have been on a _Wednesday_: for when _E_ stands for _Sunday_, _F_ must stand for _Monday_, _G_ for _Tuesday_, _A_ for _Wednesday_, _B_ for _Thursday_, _C_ for _Friday_, and _D_ for _Saturday_. Hence, as it appears that the famous Eclipse of the Sun foretold by THALES, by which a peace was brought about between the _Medes_ and _Lydians_, happened on the 28th of _May_, in the 585th year before CHRIST, it certainly fell on a _Wednesday_.
[Sidenote: _Julian Period._]
430. From the multiplication of the Solar Cycle of 28 years into the Lunar Cycle of 19 years, arises the great _Julian Period_ consisting of 7980 years; which had its beginning 764 years before the supposed year of the creation (when all the three Cycles began together) and is not yet compleated, and therefore it comprehends all other Cycles, Periods and Æras. There is but one year in the whole Period which has the same numbers for the three Cycles of which it is made up: and therefore, if historians had remarked in their writings the Cycles of each year, there had been no dispute about the time of any action recorded by them.
[Sidenote: To find the year of this Period.
And the Cycles of that year.]
431. The _Dionysian_ or vulgar Æra of _Christ_’s birth was about the end of the year of the _Julian_ Period 4713; and consequently the first year of his age, according to that account, was the 4714th year of the said Period. Therefore, if to the current year of _Christ_ we add 4713, the Sum will be the year of the _Julian_ Period. So the year 1757 will be found to be the 6470th year of that Period. Or, to find the year of the _Julian_ Period answering to any given year before the first year of CHRIST, subtract the number of that given year from 4714, and the remainder will be the year of the _Julian_ Period. Thus, the year 585 before the first year of CHRIST (which was the 584th before his birth) was the 4129th year of the said Period. Lastly, to find the Cycles of the Sun, Moon, and Indiction for any given year of this Period, divide the given year by 28, 19, and 15; the three remainders will be the Cycles sought, and the Quotients the numbers of Cycles run since the beginning of the Period. So in the above 4714th year of the _Julian_ Period the Cycle of the Sun was 10, the Cycle of the Moon 2, and the Cycle of Indiction 4; the Solar Cycle having run through 168 courses, the Lunar 248, and the Indiction 314.
[Sidenote: The true Æra of CHRIST’s birth.]
432. The vulgar Æra of CHRIST’s birth was never settled till the year 527; when _Dionysius Exiguus_, a _Roman_ Abbot, fixed it to the end of the 4713th year of the _Julian_ Period; which was certainly four years too late. For, our SAVIOUR was undoubtedly born before the Death of _Herod_ the Great, who sought to kill him as soon as he heard of his birth. And, according to the testimony of _Josephus_ (B. xvii. c. 8.) there was an eclipse of the Moon in the time of _Herod_’s last illness: which very eclipse our Astronomical Tables shew to have been in the year of the _Julian_ Period 4710, _March_ 13th, 3 hours 21 minutes after mid-night, at _Jerusalem_. Now, as our SAVIOUR must have been born some months before _Herod_’s death, since in the interval he was carried into _Ægypt_; the latest time in which we can possibly fix the true _Æra_ of his birth is about the end of the 4709th year of the _Julian_ Period. And this is four years before the vulgar _Æra_ thereof.
[Sidenote: The time of his crucifixion.]
In the former edition of this book, I endeavoured to ascertain the time of CHRIST’s death; by shewing in what year, about the reputed time of the Passion, there was a Passover Full Moon on a _Friday_: on which day of the week, and at the time of the Passover, it is evident from _Mark_ xv. 42. that our SAVIOUR was crucified. And in computing the times of all the Passover Full Moons from the 20th to the 40th year of CHRIST, after the _Jewish_ manner, which was to add 14 days to the time when the New Moon next before the Passover was first visible at _Jerusalem_, in order to have their day of the Passover Full Moon, I found that the only Passover Full Moon which fell on a _Friday_, in all that time, was in the year of the _Julian_ Period 4746, on the third day of _April_: which year was the 33d year of CHRIST’s age, reckoning from the vulgar Æra of his birth, but the 37th counting from the true _Æra_ thereof: and was also the last year of the 402d Olympiad[88], in which very year _Phlegon_ an Heathen writer tells us, _there was the most extraordinary Eclipse of the Sun that ever was known_, and that _it was night at the sixth hour of the day_. Which agrees exactly with the time that the darkness at the crucifixion began, according to the three Evangelists who mention it[89]: and therefore must have been the very same darkness, but mistaken by _Phlegon_ for a natural Eclipse of the Sun; which was impossible on two accounts, 1. because it was at the time of Full Moon; and 2. because whoever takes the pains to calculate, will find that there could be no regular and total Eclipse of the Sun that year in any part of _Judea_, nor any where between _Jerusalem_ and _Egypt_: so that this darkness must have been quite out of the common course of nature.
From the co-incidence of these characters, I made no doubt of having ascertained the true year and day of our SAVIOUR’s death. But having very lately read what some eminent authors have wrote on the same subject, of which I was really ignorant before; and heard the opinions of other candid and ingenious enquirers after truth (which every honest man will follow wherever it leads him) and who think they have strong reasons for believing that the time of CHRIST’s death was not in the year of the _Julian_ Period 4746, but in the year 4743; I find difficulties on both sides, not easily got over: and shall therefore state the case both ways as fairly as I can; leaving the reader to take which side of the Question he pleases.
Both Dr. _Prideaux_ and Sir _Isaac Newton_ are of opinion that _Daniel_’s seventy weeks, consisting of 490 years (_Dan._ chap. ix. v. 23-26) began with the time when Ezra received his commission from _Artaxerxes_ to go to _Jerusalem_, which was in the seventh year of that King’s reign (_Ezra_ ch. vii. v. 11-26) and ended with the death of CHRIST. For, by joining the accomplishment of that prophecy with the expiation of Sin, those weeks cannot well be supposed to end at any other time. And both these authors agree that this was _Artaxerxes Longimanus_, not _Artaxerxes Mnemon_. The Doctor thinks that the last of those annual weeks was equally divided between _John_’s ministry and CHRIST’s. And, as to the half week, mentioned by _Daniel_ chap. ix. v. 27. Sir _Isaac_ thinks it made no part of the above seventy; but only meant the three years and an half in which the _Romans_ made war upon the _Jews_ from spring in _A.D._ 67 to autumn in _A.D._ 70, when a final Period was put to their sacrifices and oblations by destroying their city and sanctuary, on which they were utterly dispersed. Now, both by the undoubted Canon of _Ptolemy_, and the famous Æra of _Nabonassar_, which is so well verified by Eclipses that it cannot deceive us, the beginning of these seventy weeks, or the seventh year of the reign of _Artaxerxes Longimanus_, is pinned down to the year of the _Julian_ Period 4256: from which count 490 years to the death of CHRIST, and the same will fall in the above year of the _Julian_ Period 4746: which would seem to ascertain the true year beyond dispute.
But as _Josephus_’s Eclipse of the Moon in a great measure fixes our SAVIOUR’s birth to the end of the 4713th year of the _Julian_ Period, and a _Friday_ Passover Full Moon fixes the time of his death to the third of _April_ in the 4746th year of that Period, the same as above by _Daniel_’s weeks, this supposes our SAVIOUR to have been crucified in the 37th year of his age. And as St. _Luke_ chap. iii. ver. 23. fixes the time of CHRIST’s baptism to the beginning of his 30th year, it would hence seem that his publick ministry, to which his baptism was the initiation, lasted seven years. But, as it would be very difficult to find account in all the Evangelists of more than four Passovers which he kept at _Jerusalem_ during the time of his ministry, others think that he suffered in the vulgar 30th year of his age, which was really the 33d; namely in the year of the _Julian_ Period 4743. And this opinion is farther strengthened by considering that our SAVIOUR eat his last Paschal Supper on a _Thursday_ evening, the day immediately before his crucifixion: and that as he subjected himself to the law, he would not break the law by keeping the Passover on the day before the law prescribed; neither would the Priests have suffered the Lamb to be killed for him before the fourteenth day of _Nisan_ when it was killed for all the people, _Exod._ xii. _ver._ 6. And hence they infer that he kept this Passover at the same time with the rest of the _Jews_, in the vulgar 30th year of his age: at which time it is evident by calculation that there was a Passover Full Moon on _Thursday April_ the 6th. But this is pressed with two difficulties. 1. It drops the last half of _Daniel_’s seventieth week, as of no moment in the prophecy; and 2. it sets aside the testimony of _Phlegon_, as if he had mistaken almost a whole _Olympiad_.
Others again endeavour to reconcile the whole difference, by supposing, that as CHRIST expressed himself only in round numbers concerning the time he was to lie in the grave, _Matt._ xii. 40. so might St. _Luke_ possibly have done with regard to the year of his baptism: which would really seem to be the case when we consider, that the _Jews_ told our SAVIOUR, sometime before his death, _Thou art not yet fifty years old_, John vii. 57. which indeed was more likely to be said to a person near forty than to one but just turned of thirty. And as to his eating the above Passover on _Thursday_, which must have been on the _Jewish_ Full Moon day, they think it may be easily accommodated to the 37th year of his age; since, as the _Jews_ always began their day in the evening, their _Friday_ of course began on the evening of our _Thursday_. And it is evident, as above-mentioned, that the only _Jewish Friday_ Full Moon, at the time of their Passover, was in the vulgar 33d, but the real 37th year of CHRIST’s age; which was the 4746th year of the _Julian_ Period, and the last year of the 202d _Olympiad_.
[Sidenote: Æras or Epochas.]
433. As there are certain fixed points in the Heavens from which Astronomers begin their computations, so there are certain points of time from which historians begin to reckon; and these points or roots of time are called _Æras_ or _Epochas_. The most remarkable _Æras_ are those of the _Creation_, the _Greek Olympiads_, the building of _Rome_, the _Æra_ of _Nabonassar_, the death of _Alexander_, the birth of CHRIST, the _Arabian Hegira_, and the _Persian Jesdegird_: All which, together with several others of less note, have their beginnings in the following Table fixed to the years of the _Julian Period_, to the age of the world at those times, and to the years before and after the birth of CHRIST.
