 The commentaries on Physics, On Generation and Corruption (“GC”), Meteorology and De anima are only preserved in one manuscript each, and so, presumably, had little impact. Those on Physics and GC, which are transmitted in the same manuscript, repeatedly deal with controversial matters like the eternity of the world. The last question on GC has been rendered almost entirely unreadable by overlining, presumably the owner’s reaction to the 1277 condemnation, for the title of the question was “Whether the first movement can be perpetual” and from what remains of the question it is clear that Boethius argued that, scientifically speaking, the world cannot be “new”, although according to faith it is so. Other copies of the two works must have existed, but fear of being denounced to ecclesiastical authorities may have stopped the production of new ones after the condemnation.
