In 586 B.C. the prophet Ezekiel mentions the famed wine of Izlo, on the southern edge of the plateau of Tur Abdin, in his prophecy against Tyre. The Mor Gabriel Monastery, the oldest Syriac Orthodox church in the world, was founded in 397 by the ascetic Mor Shmu'el (Samuel) and his student Mor Shem'un (Simon). According to tradition, Shem'un had a dream in which an Angel commanded him to build a House of Prayer in a location marked with three large stone blocks. When Shem'un awoke, he took his teacher to the place and found the stone the angel had placed. At this spot Mor Gabriel Monastery was built.
