In the ancient Celtic world, time as they knew it, was divided into two halves. A dark half and a light half, expressing the cycle of life and death. The light half of the year was that of the people and the living and growing, the dark half belonged to the earth and to the spirit world and sleep. Samhain was celebrated as the beginning of a new year in the Celtic calendar. For the Celts, the dark always preceded the light instead of following it. Day began at dusk, not dawn. On this the last evening of the month of October, a seasonal feast marked the end of the “light half” of the year and the beginning of the “dark half” when it was believed that the veil between the world of the living and the spirit world was the thinnest. This season was thought to be the ideal time to contact and receive wisdom from deceased ancestors, and therefore a time for solitary introspection and reflection, a time to stretch the worldly boundaries by assuming a different identity to welcome the supernatural.
