Шапур I
Mani composed seven works, six of which were written in the Syriac language, a late variety of Aramaic. The seventh, the "Shabuhragan", was written by Mani in Middle Persian and presented by him to the Sasanian emperor, Shapur I. Although there is no proof Shapur I was a Manichaean, he tolerated the spread of Manichaeism and refrained from persecuting it within his empire's boundaries.
