Titus Flavius Clemens was born in Athens of pagan parents, converted to Christianity, and studied and later taught at Alexandria. His Protrepticus or ‘Address to the Greeks’ (c.190) was designed to prove the superiority of Christianity to pagan cults and way of life, and is a copious (but biased) source of information about the pagan mysteries. He supported a fusion of Platonism and Christianity and saw pagan philosophy and the Old Testament as preparation for Christianity which is an ascent to perfect gnosis with Christ as logos.
