Legend tells us that the High King of Tara, who ruled supreme over all the Kings of Ireland, looked out from his castle one day during the festival of Eostre and saw a fire blazing away on a far hillside. Furious with this obvious disregard for the law, for which the penalty was death, he sent out soldiers to arrest the guilty party. When the soldiers arrived at the hillside they found St Patrick, the patron Saint of Ireland, piling wood onto his fire and immediately seized him. Standing before the King he was asked why he disobeyed the law, and he explained that his fire was a sign that Christ had risen from the dead and was the light of the world. The King so admired Patrick’s courage that he forgave him and became a convert to Christianity!

At Bealltainn, or May Day, every effort was made to scare away the fairies, who were particularly dreaded at this season. In the West Highlands charms were used to avert their influence. In the Isle of Man the gorse was set alight to keep them at a distance. In some parts of Ireland the house was sprinkled with holy water to ward off fairy influence. These are only a mere handful out of the large number of references available, but they seem to me to reveal an effort to avoid the attentions of discredited deities on occasions of festival once sacred to them. The gods duly return at the appointed season, but instead of being received with adoration, they are rebuffed by the descendants of their former worshippers, who have embraced a faith which regards them as demons.In like manner the fairies in Ireland were chased away from the midsummer bonfires by casting fire at them. At the first approach of summer, the fairy folk of Scotland were wont to hold a "Rade," or ceremonial ride on horseback, when they were liable to tread down the growing grain.
