Historical Context
The early Christian community in Edessa is attested from the late second and early third centuries, and the figure of Bishop Barsimaeus is associated with the consolidation of that community. The Edessene martyrology preserves accounts of several converts who suffered under the Roman administration of the region. Thathuil's story belongs to this cluster: a prominent pagan cult-official whose conversion represented both a personal transformation and a public rupture with the religious establishment of the city.
The sources for Thathuil and Bebaia are hagiographic rather than archival, and some details — including the precise relationship between Thathuil and Bebaia and the exact form of torture — vary across textual traditions. Their commemoration on September 4 is attested in the Orthodox synaxarion.
