Happy Beltane. The Gaelic May Day festival is about halfway between the equinox and the solstice. Along with Samhain (Nov 1), Imbolc (feb 1) and Lughnasadh (Aug 1), it is one of the four Gaelic seasonal festivals and is widely observed as the “first of summer”. In the agricultural cycle, it was when the cattle were driven out to the summer pastures and rituals were performed to protect them (from both natural and supernatural harm, e.g. warding off or appeasing the fairies who had a predilection to steal dairy products) and promote growth, including bonfires whose ashes and smoke were construed to have protective powers. Sometimes the cattle would be driven around a bonfire or be made to leap over flames or embers. The people themselves would do likewise. Household hearth fires and candle flames would be doused and rekindled from the Beltane bonfire. Holy wells were visited, as the first water drawn on Beltane was thought to bring good fortune. Beltane morning dew was also thought to bring good luck, maintain youthfulness, health and fertility. Yellow flowers traditionally decorated doorways and windows. Nearby small trees or bushes — “May bushes” — were decorated with yellow flowers, ribbons and other ornaments, left up for the entire month of May. At times, there were entire community Bushes and communities would vie with one another for the most handsome trees. Sometimes residents of one neihgborhood would try to steal the May Bush of another. There is probably some connection to the more commonly-known European maypole.
