 Both Latin versions were published by J.T. Muckle, “Issac Israeli, Liber de Definicionibus” in Archives d’histoire doctrinale et litteraire du moyen age, 1937–8. The longer version was translated by Gerard of Cremona (1114–1187), and appears in manuscripts (Paris B.N. 14,700; Paris B.N. 6443; Vatican Lat. 2186) as well as a printed edition Omnia opera Ysaac, from Lyons in 1515. M. Alonso speculated that the shorter version (MS Munich Lat. 8001) is a translation by Domingo Gundissalinus and predated the longer version (Alonso, 1947, pp. 295, 325) (See “Traducciones del arcediano Domingo Gundisalvo” in Al-Andalus, 1947, pp. 295, 325). Altmann and Stern challenge this hypothesis, arguing that the shorter version is an epitome of the longer version, improving the translation at points (Isaac Israeli, p. 5).
