[b] Quintus Mucius Scævola was the great lawyer of his time. Cicero draws a comparison between him and Crassus. They were both engaged, on opposite sides, in a cause before the CENTUMVIRI. Crassus proved himself the best lawyer among the orators of that day, and Scævola the most eloquent of the lawyers. _Ut eloquentium juris peritissimus Crassus; jurisperitorum eloquentissimus Scævola putaretur._ _De Claris Orat._ s. 145. During the consulship of Sylla, A.U.C. 666, Cicero being then in the nineteenth year of his age, and wishing to acquire a competent knowledge of the principles of jurisprudence, attached himself to Mucius Scævola, who did not undertake the task of instructing pupils, but, by conversing freely with all who consulted him, gave a fair opportunity to those who thirsted after knowledge. _Ego autem juris civilis studio, multum operæ dabam Q. Scævolæ, qui quamquam nemini se ad docendum dabat, tamen, consulentibus respondendo, studiosos audiendi docebat._ _De Claris Orat._ s. 306. [c] Philo was a leading philosopher of the academic school. To avoid the fury of Mithridates, who waged a long war with the Romans, he fled from Athens, and, with some of the most eminent of his fellow-citizens, repaired to Rome. Cicero was struck with his philosophy, and became his pupil. _Cùm princeps academiæ Philo, cum Atheniensium optimatibus, Mithridatico bello, domo profugisset, Romamque venisset, totum ei me tradidi, admirabili quodam ad philosophiam studio concitatus._ _De Claris Orat._ s. 306. Cicero adds, that he gave board and lodging, at his own house, to Diodotus the stoic, and, under that master, employed himself in various branches of literature, but particularly in the study of logic, which may be considered as a mode of eloquence, contracted, close, and nervous. _Eram cum stoico Diodoto: qui cum habitavisset apud me, mecumque vixisset, nuper est domi meæ mortuus. A quo, cum in aliis rebus, tum studiosissime in dialecticâ exercebar, quæ quasi contracta et adstricta eloquentia putanda est._ _De Claris Orat._ s. 309.
