protected king, although the attractions of Cornelia may also have influenced his choice. She, however, had no aspirations to share the throne of the Lagidae, and the hellenism of Tiberius and of his younger brother Caius, though deep and far-reaching, was of a kind less violent than would have been gained by transportation to Alexandria. They were trained in rhetoric by Diophanes an exile from Mitylene, and in philosophy by Blossius of Cumae, a stoic of the school of Antipater of Tarsus.[304] Many held the belief that Tiberius was spurred to his political enterprise by the direct exhortation of these teachers; but, even if their influence was not of this definite kind, there can be little doubt that the teaching of the two Greeks exercised a powerful influence on the political cast of his mind. Ideals of Greek liberty, speeches of Greek statesmen who had come forward as champions of the oppressed, stories of social ruin averted by the voice and hand of the heaven-sent legislator, pictures of self-sacrifice and of resigned submission to a standard of duty--these were lessons that may have been taught both by rhetorician and philosopher. Nor was the teaching of history different. In the literary environment in which the Gracchi moved, ready answers were being given to the most vital questions of politics and social science. Every one must have felt that the approaching struggle had a dual aspect, that it was political as well as social. For social conservatism was entrenched behind a political rampart: and if reform, neglected by the senate, was to come from the people, the question had first to be asked, Had the people a legal right to initiate reform? The historians of that and of the preceding generation would have answered this question unhesitatingly in the affirmative. The _de facto_ sovereignty of the senate had not even received a sanction in contemporary literature, while to that of the immediate past it was equally unknown. The Roman annalists from the time of the Second Punic War had revealed the sovereignty of the people as the basis of the Roman constitution,[305] and the history of the long struggle of the Plebs for freedom made the protection of the commons the sole justification of the tribunate. From the lips of Polybius himself Tiberius may have heard the impression which the Roman polity made on the mind of the educated Greek: and the fact that this was a Greek picture did not lessen its validity; for the Greek was moulding the orthodox history of Rome, and the victims of his genius were the best Roman intellects of the day. He might have learnt how in this mixed constitution the people still retained their inalienable rights, how they elected, ratified, and above all how they punished.[306] He might have gathered that the identification of the tribunate with the interests of the nobility was a perversion of its true and vital function: that the tribune exists but to assist the commons and can be
