Gundissalinus’s Shadows on the Summa Halensis

Abstract

Dominicus Gundissalinus’s contribution to the history of medieval philosophy has been meaningful especially in reason of its originality and syncretism. However, scholarship has only partially explored the explicit reception of Gundissalinus’s works in the 13^th century. This article discusses this aspect from a methodological point of view and through the examination of a specific case: the influence of Gundissalinus’s works on the Summa Halensis. After having discussed the main problems related to assessing Gundissalinus’s impact on the 13^th century, the article details some meaningful examples of explicit influence on Roger Bacon and Thomas of York. The last part of the article examines how the authors of the Summa Halensis used Gundissalinus’s De unitate et uno and a possible example of implicit influence of other works by Gundissalinus on the Summa.
