Prof. Mark Gossiaux is working to produce a book-length study of the metaphysical thought of the late thirteenth century philosopher-theologian James of Viterbo. Since only some of James’ writings are available in a critical edition, Dr. Gossiaux must make use of fourteenth century manuscripts to recover the unedited parts of James’ works. These manuscripts, written in a highly abbreviated Latin, require careful and meticulous study if their secrets are to be revealed. Dr. Gossiaux’s book, which aims to provide a complete historical reconstruction of James’ metaphysics, will make an important contribution to the scholarly understanding of late medieval philosophy.
