Originally published in 1963, this is a study of the greatness of Dante, Michelangelo and Milton, and of the differences in the power and effect of their work. This book shows how differing philosophical commitments help explain differences in the character of their greatness. The ancient treatise On the Sublime provides the starting point for these studies and in an introductory essay the author examines Longinus' obligations to Platonic and Stoic philosophy. In the essays which relate the critical doctrines of Dante, Michelangelo and Milton to philosophy, he shows how far their thought accords with Longinus' and to what degree they depend upon the same philosophic traditions. The final emphasis, however, is upon the relation of their ideas to the distinctive elements of their greatness.
