" A couple of hours after Sunset Michael Robartes returned and told me that I would have to learn the steps of an exceedingly antique dance, because before my initiation could be perfected I had to join three times in a magical dance, for rhythm was the wheel of Eternity, on which alone the transient and accidental could be broken, and the spirit set free. "

― W.B. Yeats , Rosa Alchemica
