But not only did Apollonius vivify and reconsecrate the old centres of religion for some inscrutable reason, and do what he could to help on the religious life of the time in its multiplex phases, but he took a decided, though indirect, part in influencing the destinies of the Empire through the persons of its supreme rulers. This influence, however, was invariably of a moral and not of a political nature. It was brought to bear by means of philosophical converse and instruction, by word of mouth or letter. Just as Apollonius on his travels conversed on philosophy, and discoursed on the life of a wise man and the duties of a wise ruler, with kings,[108] rulers, and magistrates, so he endeavoured to advise for their good those of the emperors who would listen to him. Vespasian, Titus, and Nerva were all, prior to their elevation to the purple, friends and admirers of Apollonius, while Nero and Domitian regarded the philosopher with dismay. During Apollonius’ short stay in Rome, in 66 A.D., although he never let the slightest word escape him that could be construed by the numerous informers into a treasonable utterance, he was nevertheless brought before Tigellinus, the infamous favourite of Nero, and subjected to a severe cross-examination. Apparently up to this time Apollonius, working for the future, had confined his attention entirely to the reformation of religion and the restoration of the ancient institutions of the nations, but the tyrannical conduct of Nero, which gave peace not even to the most blameless philosophers, at length opened his eyes to a more immediate evil, which seemed no less than the abrogation of the liberty of conscience by an irresponsible tyranny. From this time onwards, therefore, we find him keenly interested in the persons of the successive emperors. Indeed Damis, although he confesses his entire ignorance of the purpose of Apollonius’ journey to Spain after his expulsion from Rome, would have it that it was to aid the forthcoming revolt against Nero. He conjectures this from a three days’ secret interview that Apollonius had with the Governor of the Province of Bætica, who came to Cadiz especially to see him, and declares that the last words of Apollonius’ visitor were: “Farewell, and remember Vindex” (v. 10). It is true that almost immediately afterwards the revolt of Vindex, the Governor of Gaul, broke out, but the whole life and character of Apollonius is opposed to any idea of political intrigue; on the contrary, he bravely withstood tyranny and injustice to the face. He was opposed to the idea of Euphrates, a philosopher of quite a different stamp, who would have put an end to the monarchy and restored the republic (v. 33); he believed that government by a monarch was the best for the Empire, but he desired above all other things to see the “flock of mankind” led by a “wise and faithful shepherd” (v. 35).
