Michael Syncellus was a 9th-century Greek Orthodox monk, priest, and abbot of Arab origin. Born in Jerusalem around 761, he served as a synkellos for the patriarchates of both Jerusalem and Constantinople. He is primarily remembered for his steadfast opposition to iconoclasm, which resulted in decades of imprisonment and exile. A prolific scholar, he authored significant works on Greek syntax, theology, and hagiography. Following the end of iconoclasm, he helped restore the Chora monastery before his death in 846.
