Paul of Antioch (Arabic: Būlus al-Rāhib al-Anṭākī) was a Melkite Christian monk, bishop and author who lived between the 11th and 13th centuries.
[1][2] In his Letter to a Muslim Friend, Paul claims to have travelled to "the homelands of the Romans [i.e., the Byzantines], Constantinople, the country of Amalfi, some Frankish provinces, and Rome."
Many commentators view them as a literary device, a fiction that allows Paul to distance himself from the objections to Islam expressed by his European interlocutors.
David Thomas and Sidney Griffith suggest a late date, around 1200, as more likely, on the grounds that his polemical writings are unlikely to have gone unnoticed for long.
[1] The Responses to a Muslim Sheikh is a letter intending to refute moral relativism and theological determinism and defend the miracles of Jesus.
