History of Calan Gaeaf

Calan Gaeaf is often believed to be the predecessor of the U.S. festival of Halloween. Celebrated at the very beginning of winter, Calan Gaeaf was a way of getting people ready to prepare for short and cheerless days ahead. The longer nights and cool air turned out to be the perfect setting for a spooky festival. The night before Calan Gaeaf is known as ‘Nos Galan Gaeaf,’ where spirits are abroad and yet to visit people. On the night before, people stay away from churchyards, stiles, and crossroads to avoid running into spirits.

Like festivals that have to do with spirits and ghosts, Calan Gaeaf is also deeply rooted in superstitions. In the early practice of the festival, villagers would dance around a bonfire and everyone would write their names and carve a mark on rocks. These rocks were later placed in the fire. When the fire died out, the villagers would all run home, thinking that if they stayed, ‘Yr Hwch Ddu Gwta’’ (a spirit in the shape of a tailless black sow with a headless woman) or ‘Y Ladi Wen’ (a headless ghost apparition) would chase them and devour their souls.

The next morning, the villagers would return to see if the rocks still contained their mark. If the mark was wiped clean, it was considered good luck. If, however, a stone was missing, the person to whom it originally belonged was believed to be cursed with bad luck that would result in them dying within a year!
