Pantaenus, a philosopher of the stoic school, according to some old Alexandrian custom, where, from the time of Mark the evangelist the ecclesiastics were always doctors, was of so great prudence and erudition both in scripture and secular literature that, on the request of the legates of that nation, he was sent to India by Demetrius bishop of Alexandria, where he found that Bartholomew, one of the twelve apostles, had preached the advent of the Lord Jesus according to the gospel of Matthew, and on his return to Alexandria he brought this with him written in Hebrew characters. Many of his commentaries on Holy Scripture are indeed extant, but his living voice was of still greater benefit to the churches. He taught in the reigns of the emperor Severus and Antoninus surnamed Caracalla.
