Francesco d'Appignano and the Non-Existent Canon: Tracing Francesco d'Appignano's scientific legacy in Francesc Marbres, alias Johannes Canonicus, and fragments discovered along the way. (original) (raw)

In Atti del VII Convegni Internazionale su Francesco d'Appignano, a cura di Domenico Priori and Fabio Zanin, Appignano del Tronto [2018], 103-132. This paper uses Bert Roest's recent and provocative essay in Franciscan Studies 74 (2016) as a frame to talk about how the physics of Francesco d'Appignano (Francis of Marchia) became part of the work by the author known to posterity as John the Canon and to his contemporaries as Francesc Marbres. It also reports the discovery of two fragments of Francesco's Reportatio IIA and integrates them into the stemma codicum. Neither I nor Chris remember seeing proofs, so we hope the text is legible.
