Origen of Alexandria
Origen Adamantius was an early Christian scholar, theologian, and one of the most distinguished of the early fathers of the Christian Church. According to tradition, he is held to have been an Egyptian who taught in Alexandria, reviving the Catechetical School of Alexandria where Clement of Alexandria had taught.
Using his knowledge of Hebrew, he produced a corrected Septuagint. He wrote commentaries on most of the books of the Bible. In De principiis (On First Principles), he articulated one of the first philosophical expositions of Christian doctrine.
