St. Barsimæus, Bishop and Martyr
[Called by the Syrians Barsaumas.] HE was the third bishop of Edessa from St. Thaddaeus, one of the seventy-two disciples. St. Barsaumas was crowned with martyrdom, being condemned to die for his zeal in converting great multitudes to the faith, by the president Lysias, in the reign of Trajan, when that prince having passed the Euphrates, made the conquest of Mesopotamia in 114. St. Barsimæus is mentioned on the 30th of January in the Roman Martyrology, and in the Greek Mænology.
