The Law Code of Simeon of Rev-Ardashir, originally written in Persian, was translated into Syriac by a monk of Bēt-Qaṭrāyē. The Code's author, possibly the early 7th century Metropolitan mentioned in the letters of Patriarch Īšoʿ-yahb III, aims to clarify the origins of the Christian legal system, and to address family matters, including inheritance and the role of slaves.
