ELESBAAN (Saint) King (October 27) (6th century) A Christian King of Ethiopia (Abyssinia) in the first half of the sixth century, who distinguished himself by his warlike and successful expeditions in Arabia, where a Jewish usurper had almost exterminated the Christianity of the Southern part of the Peninsula. In these wars he was supported by the Byzantine Emperors, Justin I and Justinian. At the close of a long and memorable reign Saint Elesbaan abdicated and ended his life as a hermit in the exercises of prayer and penance. He died about A.D. 555. His real name seems to have been Caleb. Hence, the Abyssinians style him Calam-Negus.
