This major publication sheds new light on one of the most important artworks produced in late fifteenth century Spain. The twenty-six panels of the altarpiece of the cathedral of Ciudad Rodrigo (Castile) rank among the most beautiful and ambitious works by two of Castile’s gifted late medieval painters, Fernando Gallego and the virtually unknown Master Bartolomé. Accompanying a major new exhibition of their work, this extensively illustrated volume includes full catalog entries for each of the panels, as well as a collection of essays exploring both their cultural and artistic significance. Ranging in subject matter from the physical life and composition of the altarpiece itself, to Fernando Gallego, the Hispano-Flemish tradition in Spain and millennialism in late fifteenth-century Castile, these essays highlight individual techniques and workshop practices in the context of the cosmopolitan communities of a gothic city.
