The work was originally composed in Arabic, of which no copies are extant. It was preserved for the ages by a translation into Latin in the year 1150 by Abraham ibn Daud and Dominicus Gundissalinus, who was the first official director of the Toledo School of Translators, a scholastic philosopher, and the archdeacon of Segovia, Spain. In the 13th century, Shem Tov ibn Falaquera wrote a summary of "Fons" "Vitæ" in Hebrew, and only in 1926 was the full Latin text translated into Hebrew.
