This Sabbat is celebrated on the foreevening of 1 May. The ritual alchemy belonging to this Sabbat is Air Alchemy which is an alchemy of the Left Hand Path. It changes fire and air, calling air in the south and places the fire altar in the east. It is a ritual to empower and enchant the land and the universe. I give 4 lectures about card 32 of the Major Arcane, Air- or Summoning Alchemy, also called Morallthach, the Sword named "Great Fury". I will tell about Diarmuid, the Cherry, the Bat and the meaning of the card and the belonging rune and ogham Ghee, the lettercombination EE.
