(Perp. Fest. Cal) "March 13. Diotima, teacher of Socrates."
(Plato, Symposium, 201 d.) Socrates describes his teacher: "Diotima of Mantinea, a woman wise in this (i.e. love) and in many other kinds of knowledge. . She was my instructress."
(Lucian, Portraiture, 18) "Diotima shall be still another [model] and Diotima shall be copied not only in those qualities for which Socrates commended her, but in her general intelligence and power to give counsel".
