On October 31st after the crops were all harvested and stored for the long winter the cooking fires in the homes would be extinguished (消失). The Druids, the Celtic priests, would meet in the hilltop in the dark oak forest (oak trees were considered sacred). They would light new fires and offer sacrifices of crops and animals. As they danced around the fires, the season of the sun passed and the season of darkness would begin.
When the morning arrived the Druids would give an ember from their fires to each family who would then take them home to start new cooking fires. These fires would keep the homes warm and free from evil spirits.
The November 1st festival was called Samhain (pronounced "sow-en"). The festival would last for 3 days. Many people would parade in costumes made from the skins and heads of their animals. This festival would become the first Halloween.
