"He preached to the people of Athens and other cities the purest and noblest ethics, and the phenomena he produced were as wonderful as they were numerous and well attested.... After crossing the Hindu Kush, Appollonius had been directed by a king to the abode of the Sages, ... by whom he was taught unsurpassed knowledge. His dialogues with the Corinthian Menippus indeed give us the esoteric catechism and disclose many an important mystery of nature. Appollonius was the friend, correspondent and guest of kings and queens, and no marvelous or "magic" powers are better attested than his. At the end of his long and wonderful life he opened an esoteric school at Ephesus, and died aged almost one hundred years."
