Peter Lasko is the leading authority on the luxury arts of the Middle Ages. His book, Ars Sacra, has become the standard reference work on the subject. This collection of twenty-one papers by Professor Lasko contains two studies on sculpture, as well as a number of studies on the arts of the metalworker and ivory carver for which he is best known. There is also an essay on the ethics of restoration, and three studies on the discipline of art history.
