Titus Flavius Clemens (; c. 150 – c. 215), known as
Clement of Alexandria to distinguish him from the earlier
Clement of Rome, was a
Christian theologian who taught at the
Catechetical School of Alexandria. A convert to Christianity, he was an educated man who was familiar with
classical Greek philosophy and
literature. As his three major works demonstrate, Clement was influenced by Hellenistic philosophy to a greater extent than any other Christian thinker of his time, and in particular by
Plato and the
Stoics. His secret works, which exist only in fragments, suggest that he was also familiar with pre-Christian
Jewish esotericism and
Gnosticism. In one of his works he argued that Greek philosophy had its origin among non-Greeks, claiming that both Plato and
Pythagoras were taught by Egyptian scholars. Among his pupils were
Origen and
Alexander of Jerusalem.
