The Poetic Structure of the World is a major reconsideration of a crucial turning point in Western thought and culture: the heliocentric revolution of Copernicus and Kepler. Conceiving of their work not in terms of a history of science or astronomy, but as events embedded in a wider field of images, symbols, texts, and practices, Fernand Hallyn insists that these new representations of the universe cannot be explained by recourse to theories of "genius" and "intuition." The scientific imagination is not fundamentally different from a mythic or poetic imagination, and the work of Copernicus and Kepler, Hallyn contends, must be examined on the level of rhetorical structure. Thus the new sun-centered universe is shown to be inseparable from the aesthetic, epistemological, theological, and social imperatives of both Neoplatonism and Mannerism in the sixteenth century.
