Professor Demus describes how, by a combination of historical and archaeological method, h: recently discovered a hitherto unknown cultural and artistic movement that swept through Venice in the thirteenth century. In th; light of this discovery a number of famous Venetian works of art, mainly in St. Mark's itself, can be re-dated, and take on a new aspect.
