Abstract

This article examines the authenticity of an anonymous question on local motion extant in manuscript Madrid, Biblioteca Nacional, 4229. This quaestio discusses the motion of three types of mobile objects, namely celestial bodies, heavy and light bodies, and projectiles. A comparison of this anonymous text with three questions from the Sentences commentary of Giraldus Odonis shows that this Franciscan theologian is very likely to be the author of the anonymous question found in the Madrid manuscript, even if the precise relation between Giraldus's questions, on the one hand, and the anonymous question De motu, on the other, remains uncertain. An edition of the anonymous question is given in an appendix
