Origen; Oregenes Adamantius is considered the most important theologian in the early church. He was born c. 185 probably in Alexandria and died c. 254. Porphyry and Eusebius of Caesarea wrote about Origin presenting different accounts of his early life. Eusebius said Origen became a student of Clement of Alexandria, following him as the head of a catechetical school. Porphyry said he attended Neo-Platonist lectures delivered by Ammonius Saccas. A wealthy Christian provided Origen with people to take down dictation while Origen wrote his treatises. Origen wrote Miscellanies (Stromateis), On the Resurrection (Peri anastaseos), and On First Principles (De principiis), Hexapla, commentaries, homilies, and scholia.
