Munich, Bayerische Staadtsbibliothek Ms. C.L.M. 4643 contains a curious commentary on Boethius's Arithmetica, which deals very fully with some passages in the work and totally neglects a great many others. The principal interest of the piece lies in the fact that the parts of the Arithmetica it selects for consideration are exactly those which were of special interest to twelfth- and early-thirteenth-century students, and in particular to the successors of Hugh of St. Victor who continued to draw on the Victorine (...) tradition.
