THREE:Subsequently, with the revival of Hellenism, the Greek oracles broke silence, and regained even more than their ancient reputation, as the increased facilities for locomotion now rendered them accessible from the remotest regions.343 Sometimes the miraculous character of their responses resulted in the conversion of hardened infidels. In this connexion, the following anecdote is related by Plutarch. A certain governor of Cilicia entertained serious doubts about the gods, and was still further confirmed in his impiety by the Epicureans who surrounded him. This man, for the purpose of throwing discredit on the famous oracle of Mopsus, sent a freedman to consult it, bearing a sealed letter containing a question with whose purport neither he nor any one else except the sender was acquainted. On arriving at the oracle, the messenger was admitted to pass a night within the temple, which was the method of consultation usually practised there. In his sleep a beautiful figure appeared to him, and after uttering the words ��a black one,�� immediately vanished. On hearing this answer the governor fell on his knees in consternation, and, opening the sealed tablet, showed his friends the question which it contained, ��Shall I sacrifice a white or a black bull to thee?�� The Epicureans were confounded; while the governor offered up the prescribed sacrifice, and became thenceforward a constant adorer of Mopsus.344The general kept his own counsel then, but afterward, when it was all over, he confessed,��not to the rejoicing reporter who was making columns out of him for the papers of this, and even of many another, land,��but to the friends who had in some measure understood and believed in him, that the strain and responsibility had all but worn him out. And he was no frail man, this mighty hunter of the plains. THREE:��Ask��questions?��How far Plotinus was indebted to Ammonius Saccas for his speculative ideas is another question with respect to which the Pythagoreanising tendencies of his biographer may282 possibly have contributed to the diffusion of a serious misconception. What Porphyry tells us is this. Before leaving Alexandria, Plotinus had bound himself by a mutual agreement with two of his fellow-pupils, Herennius and Origines (not the Christian Father, but a pagan philosopher of the same age and name), to keep secret what they had learned by listening to the lectures of Ammonius. Herennius, however, soon broke the compact, and Origines followed his example. Plotinus then considered that the engagement was at an end, and used the results of his studies under Ammonius as the basis of his conversational lectures in Rome, the substance of which, we are left to suppose, was subsequently embodied in his published writings. But, as Zeller has pointed out, this whole story bears a suspicious resemblance to what is related of the early Pythagorean school. There also the doctrines of the master were regarded by his disciples as a mystery which they pledged themselves to keep secret, and were only divulged through the infidelity of one among their number, Philolaus. And the same critic proves by a careful examination of what are known to have been the opinions of Origines and Longinus, both fellow-pupils of Plotinus, that they differed from him on some points of essential importance to his system. We cannot, therefore, suppose that these points were included in the teaching of their common master, Ammonius.425 But if this be so, it follows that Plotinus was the real founder of the Neo-Platonic school; and, in all cases, his writings remain the great source whence our knowledge of its first principles is derived.
