When in the end Pythagoras thought himself fully qualified for the task he had all along had in view, he was no less strict in prescribing ample preliminaries to his own scholars. At the time that a pupil was proposed to him, the master, we are told, examined him with multiplied questions as to his principles, his habits and intentions, observed minutely his voice and manner of speaking, his walk and his gestures, the lines of his countenance, and the expression and management of his eye, and, when he was satisfied with these, then and not till then admitted him as a probationer. [58] It is to be supposed that all this must have been personal. As soon however as this was over, the master was withdrawn from the sight of the pupil; and a noviciate of three and five, in all eight years, [59] was prescribed to the scholar, during which time he was only to hear his instructor from behind a curtain, and the strictest silence was enjoined him through the whole period. As the instructions Pythagoras received in Egypt and the East admitted of no dispute, so in his turn he required an unreserved submission from those who heard him: autos iphae "the master has said it," was deemed a sufficient solution to all doubt and uncertainty. [60] To give the greater authority and effect to his communications Pythagoras hid himself during the day at least from the great body of his pupils, and was only seen by them at night. Indeed there is no reason to suppose that any one was admitted into his entire familiarity. When he came forth, he appeared in a long garment of the purest white, with a flowing beard, and a garland upon his head. He is said to have been of the finest symmetrical form, with a majestic carriage, and a grave and awful countenance. [61] He suffered his followers to believe that he was one of the Gods, the Hyperborean Apollo, [62] and is said to have told Abaris that he assumed the human form, that he might the better invite men to an easiness of approach and to confidence in him. [63] What however seems to be agreed in by all his biographers, is that he professed to have already in different ages appeared in the likeness of man: first as Aethalides, the son of Mercury; and, when his father expressed himself ready to invest him with any gift short of immortality, he prayed that, as the human soul is destined successively to dwell in various forms, he might have the privilege in each to remember his former state of being, which was granted him. From, Aethalides he became Euphorbus, who slew Patroclus at the siege of Troy. He then appeared as Hermotimus, then Pyrrhus, a fisherman of Delos, and finally Pythagoras. He said that a period of time was interposed between each transmigration, during which he visited the seat of departed souls; and he professed to relate a part of the wonders he had seen. [64] He is said to have eaten sparingly and in secret, and in all respects to have given himself out for a
