reputation is clear from the fact recorded by Pliny the younger, that a man journeyed to Rome from Cadiz for the express purpose of seeing him, and, having succeeded, returned at once. [15] The elder Pliny [16] draws a picture of him at an advanced age studying with undiminished zeal at his great work. The "old man eloquent" used to say that he had written enough for glory, and had now earned rest; but his restless mind fed on labour and would not lie idle. When completed, his book at once became the authoritative history of Rome, after which nothing was left but to abridge or comment upon it. The state of letters at Rome, while unfavourable to strictly political history, was ripe for the production of a work like Livy's. Augustus, Agrippa, and Pollio, had founded public libraries in which the older works were accessible. The emperor took a keen interest in all studies; he encouraged not merely poets but philologians and scientific writers, and he was not indisposed to protect historical study, if only it were treated in the way he approved. Rabirius, Pedo Albinovanus, and Cornelius Severus had written poems on the late wars, Ovid and Propertius on the legends embodied in the calendar; the rival jurists Labeo and Capito had wrought the _Juris Responsa_ into a body of legal doctrine; Strabo was giving the world the result of his travels in a universal geography; Pompeius Trogus, Labienus, Pollio, and the Greeks Dionysius, Dion, and Timagenes, had all treated Roman history; Augustus had published a volume of his own _Gesta_; all things seem to demand a comprehensive dramatic account of the growth of the Roman state, which should trace the process by which the world became Roman, and Rome became united in the hands of Caesar.
