Nor had the Greeks paid much attention to Roman history prior to the war with Pyrrhus in 281 B. C., although from that time onwards Greek historians devoted themselves to the study of Roman affairs. From this date the course of Roman history is fairly clear. However, as early as the opening of the fourth century B. C. the Greeks had sought to bring the Romans into relation with other civilized peoples of the ancient world by ascribing the foundation of Rome to Aeneas and the exiles from Troy; a tale which had gained acceptance in Rome by the close of the third century. The first step in Roman historical writing was taken at the close of the Second Punic War by Quintus Fabius Pictor, who wrote in Greek a history of Rome from its foundation to his own times. A similar work, also in Greek, was composed by his contemporary, Lucius Cincius Alimentus. The oldest traditions were thus wrought into a connected version, which has been preserved in some passages of Polybius, but to a larger extent in the fragments of the _Library of Universal History_ compiled by Diodorus the Sicilian about 30 B. C. Existing portions of his work (books 11 to 20) cover the period from 480 to 302 B. C.; and as his library is little more than a series of excerpts his selections dealing with Roman history reflect his sources with little contamination. Other Roman chroniclers of the second century B. C. also wrote in Greek and, although early in that century Ennius wrote his epic relating the story of Rome from the settlement of Aeneas, it was not until about 168 that the first historical work in Latin prose appeared. This was the _Origins_ of Marcus Porcius Cato, which contained an account of the mythical origins of Rome and other Italian cities, and was subsequently expanded to cover the period from the opening of the Punic Wars to 149 B. C. Contemporary history soon attracted the attention of the Romans but they did not neglect the earlier period. In their treatment of the latter new tendencies appear about the time of Sulla under patriotic and rhetorical stimuli. The aim of historians now became to provide the public with an account of the early days of Rome that would be commeasurate with her later greatness, and to adorn this narrative, in Greek fashion, with anecdotes, speeches, and detailed descriptions, which would enliven their pages and fascinate their readers. Their material they obtained by invention, by falsification, and by the incorporation into Roman history of incidents from the history of other peoples. These writers were not strictly historians, but writers of historical romance. Their chief representative was Valerius Antias.
