The Pagan Saxons celebrated the feast of Yule with plenty of ale and blazing fires, of which our Yule log is the last relic. The Yule log is actually an indoor equivalent of the outdoor bonfire of Midwinter Eve.
It is said that the Yule log must never be bought but should be received as a gift, found or taken from your own property. during medieval times, the decorated log was ceremoniously carried into the home on Christmas Eve, and placed in the fireplace. Traditionally the Yule log was lit with the saved stump of last year’s log, and then it was burnt over the twelve days of the winter celebration, and its ashes and stump were kept until the following year to sprinkle on the new log, so that the fortune would be passed on from year to year.
In France and Germany ashes from the Yule log were mixed with the cattle feed to ensure their health and in other regions, the ash was sprinkled around fruit trees to increase their yield of fruit.
