I would like to confess that at eighteen I suddenly fell in love with Romanesque architecture, and the passion has stayed with me forever. Unfortunately, while the last part of this statement may be true, the first part, however romantic, is fundamentally distorted. The under- graduate art-history teachers at Columbia University initiated and nourished my interest in Romanesque architecture, and thoroughly shaped my approach to it. I must begin a book on this subject by thank- ing them.
