Chapter I: On the series of Sibyl engravings attributed to Botticelli

246. Since I wrote the earlier lectures in this volume, I have been made more doubtful on several points which were embarrassing enough before, by seeing some better (so-called) impressions of my favorite plates containing light and shade which did not improve them.

I do not choose to waste time or space in discussion, till I know more of the matter; and that more I must leave to my good friend Mr. Reid of the British Museum to find out for me; for I have no time to take up the subject myself, but I give, for frontispiece to this Appendix, the engraving of Joshua referred to in the text, which however beautiful in thought, is an example of the inferior execution and more elaborate shade which puzzle me. But whatever is said in the previous pages of the plates chosen for example, by whomsoever done, is absolutely trustworthy. Thoroughly fine they are, in their existing state, and exemplary to all persons and times. And of the rest, in fitting place I hope to give complete--or at least satisfactory account.
