Includes bibliographical references and index.

The study of the heavens is holy: the cosmos, the creator, vision, and the soul -- Let there be light: rays in the macrocosm -- Celestial rays and the earthly world of change -- The physical nature of vision, the material image, and the soul -- Early modern ecosystems: the city, the building, the person -- Architectural theory and astrological foundations: three case studies -- The hidden power in a picture: how celestial rays are trapped in images -- Look, reflect, be changed: the great astrological vaults of the Italian Renaissance -- Conclusion.

Today few would think of astronomy and astrology as fields related to theology. Fewer still would know that physically absorbing planetary rays was once considered to have medical and psychological effects. But this was the understanding of light radiation held by certain natural philosophers of early modern Europe, and that, argues Mary Quinlan-McGrath, was why educated people of the Renaissance commissioned artworks centered on astrological themes and practices. Influences is the first book to reveal how important Renaissance artworks were designed to be.
