MARTINUS GLOSSATOR. - This name recurs several times in the glosses to the Decretum Gratiani and the Compilaciones antiquae (Cod. Vat. lat. 1367; Cod. Halen. Ye. 52, Ioh. Galensis Apparatus, Laurentii Hispanii Apparatus) and is cited by later glossators and canonists (Ugolino, Poggio, Hostiensis), but it has not been possible to identify him.
Identity with Martinus Florentinus must be ruled out, as Genzmer has proven the baselessness of Riedner's assertion that Poggio was a disciple of M. G., demonstrating that the latter died between 1158 and 1166, whereas Martinus Florentinus, canon in Bologna, appears in the Chapter acts from 1195 to 1233, is known as a canonist in 1207, and is found among the Bolognese crusaders at Damietta in 1230. For the same reason, Laspeyres' hypothesis that he is Martinus Hispanus (known between 1274 and 1298) falls away, leaving the one concerning Martinus Zamorensis (Gillmann).
