Another turn of the Great Wheel and the first harvest is upon us. This Sabbat is known as Lammas or Lughnassadh depending on where and how it is celebrated. Lammas is derived from the words “loaf mass” and refers to the harvesting of the grains, preparation and baking of bread in celebration of the gifts of the season. The God may take the form of the Green Man, the Harvest King or Grain Father. Lughnassadh gives honor to the Celtic Solar God, Lugh and his cycle of waxing and waning energy. It is his willing sacrifice that ensures that this and the subsequent harvests will be prolific in their bounty. Regardless of what title is given to this Sabbat the themes of gathering what has come to peak, the sacrificing of what must be offered for continued survival and the carrying forward of what has been purposefully selected are prevalent.
