Edgar Allen Poe's influence on the twentieth century French writer Paul Valery was profound, much more so than on Baudelaire and Mallarme. This book is the first comprehensive study of Poe's influence of Valery and is based on Valery's own concept of literary influence. Valery discovered in Poe's tales and literary essays a Drama of the intellect that was to inspire his Evening with Monsieur teste, Agathe, and Introduction to the method of Leonardo Da Vinci. Valery's poetics and approach to literary criticism have direct connections to Poe's Philosophy of Composition and Poetic Principle. Valery's only essay devoted to his American mentor, On Poe's Eureka, recognizes the importance of the cosmological poem in Valery's intellectual development. Eureka awakened in him an interest in science and mathematics that lasted a lifetime and inspired him to apply scientific analysis to literary genius, the first writer to place creative work on an analytical basis and explore the psychological aspects of literature.
