These are only some of the most known losses; but in reading contemporary writers we are perpetually discovering many important ones. We have lost two precious works in ancient biography: Varro wrote the lives of seven hundred illustrious Romans; and Atticus, the friend of Cicero, composed another, on the acts of the great men among the Romans. When we consider that these writers lived familiarly with the finest geniuses of their times, and were opulent, hospitable, and lovers of the fine arts, their biography and their portraits, which are said to have accompanied them, are felt as an irreparable loss to literature. I suspect likewise we have had great losses of which we are not always aware; for in that curious letter in which the younger Pliny describes in so interesting a manner the sublime industry, for it seems sublime by its magnitude, of his Uncle,[27] it appears that his Natural History, that vast register of the wisdom and the credulity of the ancients, was not his only great labour; for among his other works was a history in twenty books, which has entirely perished. We discover also the works of writers, which, by the accounts of them, appear to have equalled in genius those which have descended to us. Pliny has feelingly described a poet of whom he tells us, "his works are never out of my hands; and whether I sit down to write anything myself, or to revise what I have already wrote, or am in a disposition to amuse myself, I constantly take up this agreeable author; and as often as I do so, he is still new."[28] He had before compared this poet to Catullus; and in a critic of so fine a taste as Pliny, to have cherished so constant an intercourse with the writings of this author, indicates high powers. Instances of this kind frequently occur. Who does not regret the loss of the Anticato of Cæsar? The losses which the poetical world has sustained are sufficiently known by those who are conversant with the few invaluable fragments of Menander, who might have interested us perhaps more than Homer: for he was evidently the domestic poet, and the lyre he touched was formed of the strings of the human heart. He was the painter of passions, and the historian of the manners. The opinion of Quintilian is confirmed by the golden fragments preserved for the English reader in the elegant versions of Cumberland. Even of Æschylus, Sophocles, and Euripides, who each wrote about one hundred dramas, seven only have been preserved of Æschylus and of Sophocles, and nineteen of Euripides. Of the one hundred and thirty comedies of Plautus, we only inherit twenty imperfect ones. The remainder of Ovid's Fasti has never been recovered. I believe that a philosopher would consent to lose any poet to regain an historian; nor is this unjust, for some future poet may arise to supply the vacant place of a lost poet, but it is not so with the historian. Fancy may be supplied; but Truth once lost in the annals of mankind leaves a chasm never to be filled.
