Hello! Got a late start for Beltane this year! Here’s a little history of this holiday, from wikipedia:
Beltane is mentioned in some of the earliest Irish literature and it is associated with important events in Irish mythology. It marked the beginning of summer and was when cattle were driven out to the summer pastures. Rituals were performed to protect the cattle, crops and people, and to encourage growth. Special bonfires were kindled, and their flames, smoke and ashes were deemed to have protective powers. The people and their cattle would walk around the bonfire, or between two bonfires, and sometimes leap over flames or embers. All household fires would be doused and then re-lit from the Beltane bonfire. Doors, windows, byres and the cattle themselves would be decorated with yellow May flowers, perhaps because they evoked fire. In parts of Ireland, people would make a May Bush; a thorn bush decorated with flowers, ribbons and bright shells. Holy wells were also visited, while Beltane dew was thought to bring beauty and maintain youthfulness. Many of these customs were part of May Day or Midsummer festivals in other parts of Great Britain and Europe.
I personally found the “May bush” part interesting, so here’s some more information on that, same source:
Flowers and May Bushes
Yellow flowers such as primrose, rowan, hawthorn, gorse, hazel and marsh marigold were set at doorways and windows in 19th century Ireland, Scotland and Mann. Sometimes loose flowers were strewn at the doors and windows and sometimes they would be made into bouquets, garlands or crosses and fastened to them. They would also be fastened to cows and equipment for milking and butter making. It is likely that such flowers were used because they evoked fire. Similar May Day customs are found across Europe.
The May Bush was popular in parts of Ireland until the late 19th century. This was small tree, typically a thorn tree, that would be decorated with bright flowers, ribbons, painted shells, and so forth. There were household May Bushes (which would be set outside each house) and communal May Bushes (which would be set in a public spot or paraded around the neighbourhood). In Dublin and Belfast, May Bushes were brought into town from the countryside and decorated by the whole neighbourhood. Each neighbourhood vied for the most handsome tree and, sometimes, residents of one would try to steal the May Bush of another. This led to the May Bush being outlawed in Victorian times. In some places, it was customary to dance around the May Bush, and at the end of the festivities it was burnt in the bonfire. Thorn trees were seen as special trees and were associated with the sí or fairies. The custom of decorating a May Bush or May Tree was found in many parts of Europe. Frazer believes that such customs are a relic of tree worship and writes: “The intention of these customs is to bring home to the village, and to each house, the blessings which the tree-spirit has in its power to bestow.” Emyr Estyn Evans suggests that the May Bush custom may have come to Ireland from England, because it seemed to be found in areas with strong English influence and because the Irish saw it as unlucky to damage certain thorn trees. However, “lucky” and “unlucky” trees varied by region, and it has been suggested that Beltane was the only time when cutting thorn trees was allowed. The practice of bedecking a May Bush with flowers, ribbons, garlands and coloured shells is found among the Gaelic diaspora, most notably in Newfoundland, and in some Easter traditions on the East Coast of the United States.
