Samhain: Season of Death and Renewal [View all]

As the nights lengthen and the leaves take on their autumn colours, many of our cities prepare for a seasonal festival dominated by dark and frightening imagery. Ghosts, skeletons, hags, nocturnal creatures such as cats and bats, and grinning monster faces peer out at us from shop windows. Much of it is just commercialism, yet there is no denying that the atmosphere of the holiday still has a profound effect on the modern psyche -- as we can see from the spontaneous outrageousness of Hallowe'en parades, the creative expressions of death-related themes, and the general surge in mischief-making. All these customs, however, are a diffuse reflection of the beliefs and practices of the Celtic populations of Europe, for whom this feast was a crucial turning-point in the flow of time.
