The Ivory Workers of the Middle Ages by Anna Maria Cust

This little book can do no more than humbly touch the fringe of a large subject; but if it leads the reader to a further study of this beautiful craft, it will have amply fulfilled its duty.
I must express my deep obligation to the magnificent volume on ivories by M. Emile Molinier, whose masterly arrangement of a very fragmentary and scattered subject is a model of lucidity; and also to Dr. Hans Graeven, whose scholarly researches and excellent photographs are indispensable for a real study of the craft.
