Although it is the opinion of some critics that our literary losses do not amount to the extent which others imagine, they are however much greater than they allow. Our severest losses are felt in the historical province, and particularly in the earliest records, which might not have been the least interesting to philosophical curiosity. The history of Phoenicia by Sanchoniathon, supposed to be a contemporary with Solomon, now consists of only a few valuable fragments preserved by Eusebius. The same ill fortune attends Manetho's history of Egypt, and Berosu's history of Chaldea. The histories of these most ancient nations, however veiled in fables, would have presented to the philosopher singular objects of contemplation. Of the history of Polybios, which once contained forty books, we have now only five; of the historical library of Diodorus Siculus fifteen books only remain out of forty; and half of the Roman antiquities of Dionysius Helicarnassensis has perished. Of the eighty books of the history of Dion Cassius, twenty-five only remain. The present opening book of Ammianus Marcellinus is entitled the fourteenth. Livy's history consisted of one hundred and forty books, and we only possess thirty-five of that pleasing historian. What a treasure has been lost in the thirty books of Tacitus! little more than four remain. Murphy elegantly observes, that "the reign of Titus, the delight of human kind, is totally lost, and Domitian has escaped the vengeance of the historian's pen." Yet Tacitus in fragments is still the colossal torso of history. Velleius Paterculas, of whom a fragment only has reached us, we owe to a single copy: no other having ever been discovered, and which has occasioned the text of this historian to remain incurably corrupt. Taste and criticism have certainly incurred an irreparable loss in that _Treatise on the Causes of the Corruption of Eloquence_, by Quintilian; which he has himself noticed with so much satisfaction in his "Institutes." Petrarch declares, that in his youth he had seen the works of Varro, and the second Decad of Livy; but all his endeavours to recover them were fruitless.
