Nisibis Baptistery inscription
I have been searching for the Greek text of the inscription from the baptistery in Nisibis. I know that it is translated by Sebastian Brock in the introduction to his volume of the Hymns on Paradise from SVS Press, but I have not been able to find a citation for the Greek text. Does anyone know where that can be found or, even better, a photograph or drawing of the inscription in situ?
Any help would be most appreciated.
