Didymus the Blind

Didymus (Latin; Didymos gr, * 310 or 313 in Alexandria; † around 398 ibid ), called the blind man, was an ancient Christian writer.

Although Didymus at the age of four years, even before he had learned to read, was blind, he acquired all the knowledge of his time. When he entered the service of the Church, he was employed as a teacher in the catechetical school of Alexandria, where he lived until a ripe old age and worked. Among his pupils were Jerome and Rufinus.

Didymus was a faithful follower of Origen, but also fought strongly against the views of the Arians and against those of the Manicheans.

His surviving writings show a comprehensive knowledge of the Bible and are of high theological level. Among them are the title De Trinitate, De Spiritu Sancto ( by Jerome translated into Latin ), Adversus Manichaeos, and notes and interpretations on various books of the Bible, especially the Psalms, and the Catholic Epistles.
