The Greek legend of "Barlaam and Ioasaph", sometimes mistakenly attributed to the 7th century John of Damascus <ref>Proved by Zotenberg in "Notices sur le livre de Barlaam et Josaphat" (Paris, 1886) and by Hammel in "Verhandl. des 7 interneat. Orientalisten Congresses", Semit. Section (Vienna, 1888).</ref> but actually written by the Georgian monk Euthymios in the 11th century <ref>First published by Boissonade in "Anecdota Graeca" (paris, 1832), IV, and is reproduced in Migne, PG, XCVI, among the works of St. John Damascene</ref>, Oriental Buddhists say was ultimately derived, through a variety of intermediate versions (Arabic and Georgian) from the life story of the Buddha. The king-turned-monk Ioasaph (Georgian Iodasaph, Arabic Yūdhasaf or Būdhasaf) ultimately derives his name from the Sanskrit Bodhisattva, the name used in Buddhist accounts for Gautama before he became a Buddha. Barlaam and Ioasaph were placed in the Greek Orthodox calendar of saints on [[August 26]], and in the West they were entered as "Barlaam and Josaphat" in the Roman Martyrology on the date of [[November 27]].
