This book presents four case studies that interrogate how German fifteenth-century painted triptychs engage with, and ultimately blur various boundaries. Some of the boundaries are internal to the triptych format, for example, transgressed frames between narratives scenes on triptychs’ interiors, or interconnections between imagery on triptychs’ interiors and exteriors. Other blurred boundaries are regional ones between the Netherlands and Cologne; metaphysical ones between heaven and earth; and artistic distinctions between the media of painting and sculpture.
