Beltane is a Pagan holiday, and one of the eight Sabbats. It falls about halfway between the spring equinox (Ostara) and the coming summer solstice, Litha. The holiday celebrates spring at its peak, and the coming summer. Beltane also sometimes goes by the name May Day. This holiday is associated very strongly with fertility for pagans.
This festival is often commemorated with bonfires, maypoles, dancing, and performing fertility rituals. Beltane is a Celtic word, meaning “the fires of Bel.” Bel, likely referred to the Celtic sun god, Belenus. The Celts used to light two bonfires because they believed it would purify themselves, as well as increase their fertility. They would pass cattle between the two fires, with the belief that it would purify the cattle, and ensure the fertility of the herd. Although this is not a ritual that is practiced now, modern pagans still light bonfires and practice fertility rituals on this day.
