The Celtic people, who lived more than 2000 years ago feared the evening of Oct. 31 more than any other day of the year. It was the eve of their festival of Samhain. Samhain was a joyful harvest festival that marked the death of the old year and the beginning of a new one. The day itself was a time for paying homage to the sun god Baal who had provided the people with the ripened grain for use in the upcoming winter. Come evening evil spirits were everywhere.
