Barsimaeus z Edessy was a bishop of Edessa, located in present-day Şanlıurfa, who is honored as a martyr. According to traditional accounts, he served as the third bishop of the region and lived during the early second century. He is said to have been executed around 114 AD during the reign of Emperor Trajan. While some historical analyses suggest his story might actually refer to a later bishop from the mid-third century, he remains a significant figure in the Christian tradition of Edessa.
