Happy May eve.
"In modern British and American popular culture, Halloween is the night most associated with the nocturnal activities of witches and the souls of the dead. But in much of Europe the 30 April or May Eve, otherwise known as Walpurgis Night, was another moment when spirits and witches were thought to roam about.
The life and death of Saint Walpurga, who was born in Dorset, England, in the eight century, has nothing to do with witchcraft or magic, though. She travelled to Germany on missionary work, and became abbess of a nunnery at Heidenheim, dying there in the late 770s.
The 1 May became her feast day because it was when her relics were transferred to Eichstätt in the 870s. The association of witchcraft with May Eve is actually to do with venerable rituals for protecting livestock at a time in the agricultural calendar when animals were traditionally moved to summer pastures. Bonfires were lit by communities across Europe to scare aware predators. In sixteenth-century Ireland, hares were killed on May Day, in the belief that they were shape-shifting witches bent on sucking cows dry and stealing butter. In Scotland, pieces of Rowan tree were placed above the doors of cow byres to keep witches away."
