Didymus, [2539] of Alexandria, becoming blind while very young, and therefore ignorant of the rudiments of learning, displayed such a miracle of intelligence as to learn perfectly dialectics and even geometry, sciences which especially require sight. He wrote many admirable works: Commentaries on all the Psalms, Commentaries on the Gospels of Matthew and John, On the doctrines, also two books Against the Arians, and one book On the Holy Spirit, which I translated in Latin, eighteen volumes On Isaiah, three books of commentaries On Hosea, addressed to me, and five books On Zechariah, written at my request, also commentaries On Job, and many other things, to give an account of which would be a work of itself. [2540] He is still living, and has already passed his eighty-third year.
