Eusebius says that Clement, having succeeded Pantaenus, had charge at that time of the catechetical instruction in Alexandria, so that Origen also, while still a boy, was one of his pupils — and by at that time he means the reign of Severus. Jerome says he led the school after the death of his master, and Jerome's own editor puts Pantaenus' death about 216, which cannot be squared with a school Clement had already left by 203. The two cannot both be right and this dataset does not pretend to choose: the event runs from 190 to 202, which is the span inside which every account puts him teaching, and the disagreement is stated rather than resolved. What he taught is not in doubt. The Stromateis argue that philosophy was given to the Greeks as the law was given to the Jews, a schoolmaster to bring them to Christ, and that a Christian has no business being afraid of a book.
