 A single Hebrew translation (Shacar ha-Yesodot le-Aristo) is extant in manuscript Mantua 28c, folios 16r–18r. This unsigned work was initially regarded as an anonymous commentary on Aristotle. Altmann, developing a hypothesis first proposed by Gershom Scholem, argues that this text is the work of Isaac Israeli. Also called the Mantua Text, it is available in English translation by Altmann in two publications—Journal of Jewish Studies, vii (1956) pp. 31–57 and in Altmann and Stern’s Isaac Israeli, pp. 119–32.
