Demetrius Pepanus a Greek theologian, was born on the island of Chios about 1620. He was sent to Rome to finish his studies, and entered into orders, but was released from his vows on account of his health. He returned to his native land, but left the island of Chios with his wife and children in 1655, and it is supposed that he perished in a shipwreck. All his theological writings were intended to bring back the Greek schismatics to the Catholic Church. They were discovered at Chios by the English consul Steflio Rafaelli, and were published under the title Demetrii Pepani Domestici Chii Opera quae Reperiuntur (Rome, 1781, 2 volumes).
