Theodosius Romanus, Syriac Orthodox patriarch of Antioch

Theodosius Romanus was the Patriarch of Antioch and head of the Syriac Orthodox Church from 887 until his death in 896.

The Syriac Orthodox Church, also informally known as the Jacobite Church, is an Oriental Orthodox denomination that originated from the Church of Antioch. The church currently has around 1.5 million followers worldwide. The church upholds the Miaphysite doctrine in Christology and employs the Liturgy of Saint James, associated with James the Just. Classical Syriac is the official and liturgical language of the church.

Antioch on the Orontes was a Hellenistic Greek city founded by Seleucus I Nicator in 300 BC. One of the most important Greek cities of the Hellenistic period, it served as the capital of the Seleucid Empire and later as regional capital to both the Roman and Byzantine Empire. During the Crusades, Antioch served as the capital of the Principality of Antioch, one of four Crusader states that were founded in the Levant. Its inhabitants were known as Antiochenes. The remains of the ancient city of Antioch are mostly buried beneath alluvial deposits from the Orontes River. The modern city of Antakya, in Hatay Province of Turkey, lies in its place.
