Miscellanies 1.23.153

It is clear, then, that earlier, when the child was circumcised, his parents gave him a name, and he was called Joachim. He also had a third name in heaven after his assumption, as the initiated say: Melchi. When he came of age, he was taught arithmetic, geometry, rhythm, harmony, and further meter and music by the most distinguished of the Egyptians, and besides the philosophy expressed through symbols, which they display in hieroglyphic letters. The rest of the general education Greeks taught him in Egypt, as a royal child, as Philo says in the Life of Moses; and he also learned the letters of the Assyrians and the knowledge of heavenly things from the Chaldeans and the Egyptians; hence in the Acts he is said to have been “educated in all the wisdom of the Egyptians.” Eupolemus, in his work on the kings in Judea, says that Moses was the first wise man, and first handed on grammar to the Jews, that the Phoenicians received it from the Jews, and the Greeks from the Phoenicians. When he reached manhood, he increased his prudence, zealous for the education of his kin and ancestors, even to striking and killing the Egyptian who was unjustly attacking the Hebrew.
