Book excerpt: This publication accompanies an exhibition of approximately 120 works of art and science loaned mostly from the Royal Collection of Spain (Patrimonio Nacional) to the Seattle Art Museum. Featuring the work of such artists as Bosch, Titian, El Greco, Bernini, Vel¾zquez, Murillo, Zubar¾n, and Goya, this publication includesøpaintings, sculpture, tapestries, scientific instruments, maps, armor, books, and documents. Eight essays provide historical context and artistic explication. Chronologically organized, the book charts the evolution of Spanish attitudes toward knowledge, exploration, and faith during three dynasties of Spain?s golden age, when the fervor for scientific and geographical knowledge coexisted with the expansion of empire and promotion of Christianity. The four themes of the exhibition are: The Image of Empire; Spirituality and Worldliness; Encounters across Cultures; Science and the Court. Spain in the Age of Exploration, 1492?1819, presents art and science from one of the most ambitious, magnificent, and complex enterprises in history.
