The number of instances in which it is possible in this country to assign, even tentatively, particular groups of medieval works of art to particular craftsmen is not so great that the addition of another such group can be without interest, or even without importance. Certain evidence exists which may justify the addition, to the list of recognized craft-centres, of a group of woodcarvers working originally at Ripon and dwelling there, but executing work widely distributed, and also imitated, over Northern England. That evidence must first be examined in order to establish the use of such a title as ‘The Ripon School’.
