Dionysian

The Apollonian and the Dionysian are philosophical and literary concepts represented by a duality between the figures of Apollo and Dionysus from Greek mythology. Its popularization is widely attributed to the work The Birth of Tragedy by Friedrich Nietzsche, though the terms had already been in use prior to this, such as in the writings of poet Friedrich Hölderlin, historian Johann Joachim Winckelmann, and others. The word Dionysian occurs as early as 1608 in Edward Topsell's zoological treatise The History of Serpents. The concept has since been widely invoked and discussed within Western philosophy and literature.
