Beltane, or Bealtaine, is the Gaelic May Day festival marking the start of summer, traditionally celebrated on May 1 in Ireland, Scotland, and the Isle of Man. It is one of the four main Gaelic seasonal festivals, alongside Samhain, Imbolc, and Lughnasadh. Historically, Beltane involved rituals to protect livestock, people, and crops, often using symbolic bonfires whose flames, smoke, and ashes were believed to have protective powers. Cattle were driven between fires, homes decorated with yellow May flowers, and offerings made to the aos sí. Modern revivals continue as cultural events and in Celtic-inspired neopagan and Wiccan traditions. https://en.wikipedia.org/wiki/Beltane#:~:text=It is one of the,bring beauty and maintain youthfulness.
