The work of Louis Zukofsky has been gaining exposure as a new generation of poets and scholars rediscover the American avant-garde tradition. Concurrently, interest in Guillaume Apollinaire's work has grown in recent years as English departments re-explore international modernism. In this extended essay, one of the American literary giants of the 20th Century provides deep readings of the French modernist's entire oeuvre and provides insight into his own formative aesthetic. Two sections of the essay were published in Westminster Magazine in 1932; the complete book is available here for the first time in English. The book builds its arguments with extensive quotations from Apollinaire's poems in their orignal French; this bilingual edition is the latest offering in what Publisher's Weekly has hailed as an essential series.
