"What is inspiration?" is a question that is continually asked. The derivation of the word supplies two related answers. "Inspiration" may be the breathing-in by the poet of intoxicating fumes from an intoxicating cauldron, ...containing probably a mash of barley, acorns, honey, bull's blood and such sacred herbs as icy, hellebore and laurel, or mephitic fumes from an underground vent as at Delphi, or the fumes that rise to the nostrils when toadstools are chewed. These fumes induce the paranoid trance in which time is suspended, though the mind remains active and can relate its proleptic or analeptic apprehensions in verse.
But "inspiration" may also refer to the inducement of the same poetic condition by the act of listening to the wind, the messenger of the Goddess Cardea in a sacred grove.
