Teacher of Apollonius of Tyana, from Tarsus of Cilicia.[1] "For Apollonius, advancing into the age for learning grammar, was showing strength in memory and fortitude in studying, and his language was Attic, and he was not corrupted in his speech by his countrymen; and all eyes were directed towards him, for he was also conspicuous in his appearance. When he was 14 years old [his father] brought him to Tarsus of Cilicia, to Euthydemos, who became his teacher.[2] He became attached to his teacher, but he considered the character of the city strange and not good for pursuing philosophy in. For nowhere were people more addicted to luxury -- jokers and brutes all -- and they were more interested in their linens than the Athenians were in wisdom. A river, the Kydnos, flowed through the city, and they used to sit alongside it just like water birds getting drunk on the water.[3] Therefore he transported his teacher, after obtaining leave from his father, to Aigai nearby, where there was peace and quiet conducive to someone intending to philosophize, and the studies more vigorous, and a shrine [sacred] to Asclepius manifest to humans.[4] Here the Platonists began to study philosophy with him, and the followers of Chrysippus and the Peripatetics;[5] nor did he avoid study of the works of Epicurus." And his teacher of the works of Pythagoras [was] Euxenus.[6]
