Debussy’s creative world was deeply enmeshed in the cultural field of the French capital. Steeped in a post-Enlightenment worldview centred on exploration, accumulation of knowledge, and scientific discovery, no aspect of human experience and its habitats was deemed out of bounds in this path to creative accretion. Like many of his contemporaries, Debussy became fascinated by a wealth of new ideas about the world and the human condition that exploded onto the scene during his lifetime. Mysticism and occultism expanded the horizon within which to understand the mind and its creative potential; archaeological discoveries from Greece and Rome brought alive a past that belied the bland classicism so revered only decades earlier; and a rich smorgasbord of historical research – one that encompassed music and its practice – provided new materials from the foreign worlds of medieval, if not mythical, pasts. Over the course of Debussy’s life, these currents were woven together into the conceptual framework that sustained his creative world and that he claimed continually to renew rather than reproduce.
