Severus Sebokht (Classical Syriac: ܣܐܘܝܪܐ ܣܝܒܘܟܬ),[1] also Seboukt of Nisibis, was a Syriac scholar and bishop who was born in Nisibis, Syria in 575 and died in 667.
Although little is known about his early life, he was one of the leading figures in Syria in the 7th century.
In 612, he left the post because of a doctrinal dispute with the Church of the East.
[2] His student, Jacob of Edessa (d. 708), was the major representative of “Christian Hellenism".
His treatise contained 25 chapters and provided detailed explanations of the measurements of the movements of heavenly bodies.
