This is a nonchronological introduction to Baroque, one of the great periods of European art. John Martin's descriptions of the essential characteristics of the Baroque help one to gain an understanding of the style. His illustrations are informative and he has clearly looked with a fresh eye at the works of art themselves. In addition to the more than 200 illustrations, the volume contains an appendix of translated documents.
