W. B. Yeats is arguably the greatest English-language poet of the Twentieth Century, yet the majority of his work is little known today outside of academia. He was also a playwright, novelist, author of a psycho-spiritual history of thought, Irish patriot, occult master, and creator of a religious/philosophical mythology. His beautiful, mystical, difficult works span (and indeed, define) at least three phases of late-19th- and early-to-mid-20th-century literature, providing an inescapable influence on authors of his time and thereafter. This module provides an overview of his poetry, from his early "Celtic twilight" phase through his modernist explorations to his late, great final works. We'll also glance at his drama and literary networks. Along the way, we'll explore a little bit about his life, social context, politics, spiritual explorations, and practical magic.
