The Night of the Witches. In the Teutonic calendar, April 30, not October 31, was the night that the witches congregated to celebrate their Work through ecstatic dance, wild music and revelry. The witches fêted with spirits, fairies, and a bevy of otherworldy creatures atop Brockenberg peak in the Harz region of Germany, where they lit an enormous bonfire and cavorted naked until midnight... at which point they donned their robes, boarded their brooms, flying rams and sacred goats, scooped up their cat familiars, and sped off into the night. In later days, it was believed that on this night the witches conjured the devil, who would then select one of them for his bride. This perfume is the scent of the witches' revel: German fir and forest herbs, incense and bonfire smoke, infernal flora, glowing amber, and the wet, glimmering scent of skin warmed by dance.
