 The period of greatest innovation and sophistication in the medieval insolubilia-literature seems to have been the second quarter of the fourteenth century. After about 1350, less original work is known. Insolubles continued to be discussed, but it seems that for the most part the theories adopted were variations or elaborations of the ones already seen. Paul of Venice (1499), writing in about 1396–7, in the final section of his Logica Magna, lists fifteen theories in addition to his own, supplementing Bradwardine’s list of nine with later developments, but most from before 1350 (see Spade 1973: 82–4). This later period is not yet fully researched, however, so it is too early for a clear verdict.
