Another account of the early seventh century comes from Sebeos who was an Armenian bishop of the House of Bagratuni. His account indicates he was writing at a time when memories of sudden eruption of the Arabs were fresh. He knows Muhammad's name, that he was a merchant by profession, and hints that his life was suddenly changed by a divinely inspired revelation. Sebeos is the first non-Muslim author to present us with a theory for the rise of Islam that pays attention to what the Muslims themselves thought they were doing.
