The opening as it read in 2005
Isaac Ben Solomon Israeli (circa 850 - 950 ) was a Jewish philosopher who wrote Kitab al Istiksat in Arabic . It was translated into Hebrew under the title Sefer Hayesodoth and into Latin as De Elementis . He also wrote a treatise on definitions and commentaries on the biblical Book of Genesis and the mystical Sefer Yetzirah , the oldest Kabbalistic work in known existence. The Christian monk Constantine of Carthage translated several of Israeli's medical treatises into Latin in 1087 , using them as textbooks at the University of Salerno , the earliest university in Western Europe , but omitted the real author's name, which remained unknown to the public until 1515 when Opera Omnia Isaci was put into print at Lyons , France .1
