Several of his letters are preserved; they are in admirable taste, but do not present any special points for criticism. With Caesar ends the collection of genuine letter-writers, who wrote in conversational style, without reference to publicity. In after times we have indeed numerous so- called letters, but they are no longer the same class of composition as these, nor have any recent letters the vigour, grace, and freedom of those of Cicero and Caesar. A friend of many great men, and especially of Atticus, CORNELIUS NEPOS (74?-24 B.C.) owes his fame to the kindness of fortune more than to his own achievements. Had we possessed only the account of him given by his friends, we should have bewailed the loss of a learned and eloquent author. [64] Fortunately we have the means of judging of his talent by a short fragment of his work _On Illustrious Men_, which, though it relegates him to the second rank in intellect, does credit to his character and heart. [65] It consists of the lives of several Greek generals and statesmen, written in a compendious and popular style, adapted especially for school reading, where it has always been in great request. Besides these there are short accounts of Hamilcar and Hannibal, and of the Romans, Cato and Atticus. The last-mentioned biography is an extract from a lost work, _De Historicis Latinis_, among whom friendship prompts him to class the good-natured and cultivated banker. The series of illustrious men extended over sixteen books, and was divided under the headings of kings, generals, lawyers, orators, poets, historians, philosophers, and grammarians. To each of these two books were devoted, one of Greek, and one of Latin examples. [66] Of those we possess the life of Atticus is the only one of any historical value, the rest being mere superficial compilations, and not always from the best authorities. Besides the older generation, he had friends also among the younger. Catullus, who like him came from Gallia Cisalpina, pays in his first poem the tribute of gratitude, due probably to his timely patronage. The work mentioned there as that on which the fame of Nepos rested was called _Chronica_. It seems to have been a laborious attempt to form a comparative chronology of Greek and Roman History, and to have contained three books. Subsequently, he preferred biographical studies, in which field, besides his chief work, he edited a series of _Exempla_, or patterns for imitation, of the character of our modern _Self Help_, and intended to wean youthful minds from the corrupt fashions of their time. A _Life of Cicero_ would probably be of great use to us, had fortune spared it; for Nepos knew Cicero well, and had access through Atticus to all his correspondence. At Atticus's request he wrote also a biography of Cato at greater length than the short one which we possess. It has been observed by Merivale [67] that the Romans were specially fitted for biographical writing.
