Time and the Crystal

"A brilliant achievement. The range of learning is enormous, both in medieval scientific and philosophical lore and poetry and in the vast secondary literature on Dante. The authors bring the best traditions of Anglo-American formal analysis to bear upon the petrose and produce powerful and original interpretations. . . . This is a book that all serious readers of Dante's poetry--both of the petrose and the Comedy --will want to read."--David Quint, author of Origin and Originality in Renaissance Literature
