Gabriel of Sinjar

Gabriel of Sinjar (Classical Syriac: ܓܒܪܐܝܠ ܕܫܝܓܪ, Gaḅriyel d'Šiggar) was a court physician (drustbed) of the Sasanian shah Khosrow II (r. 590–628).

According to one account he became a court physician (drustbed) after curing the sterility of the shah's favourite wife, Shirin, who eventually gave birth to a son named Mardanshah.

Shirin also influenced by Gabriel, tried to replace Dyophysitism (Church of the East) with Miaphysitism as the official form of Christianity in the Iranian empire.

[2][3] In the 612 disputation, Babai the Great presented the Sasanians' first clear and "official" Miaphysite christology which did as expected cause schisms amongst members of his church.

[2][5] The news of this event circulated widely across the elites of Ctesiphon, and demonstrated that the court was willing to exert violence in order to preserve the Zoroastrian religion.
