Basil of Caesarea, on Exod 34:29

“And when Moses came down from the mount Sinai, he held the two tables of the testimony, and he knew not that his face was horned from the conversation of the Lord.”

“Every soul is beautiful which is considered by the standard of its own virtues. But most beautiful, true and lovely, which can be contemplated by him alone who has purified his mind, is that of the divine and blessed nature. He who gazes steadfastly at the splendor and graces of it receives some share from it, as if from an immersion, tinging his own face with a sort of brilliant radiance. Whence Moses also was made resplendent in face by receiving some share of beauty when he held converse with God. Therefore he who is conscious of his own beauty utters this act of thanksgiving: "O Lord, in your favor, you gave strength to my beauty."”
