Calan Gaeaf

Dancing

On Nos Calan Gaeaf, women and children would dance around a bonfire and everyone would write their names on, or otherwise mark, rocks and place them in and around said fire. When the fire started to die out,^[5] they would all run home, believing if they stayed, Yr Hwch Ddu Gwta (a bad omen that took the form of a tailless black sow with a headless woman) or Y Ladi Wen ("the white lady", a ghostly apparition often said to be headless) would chase them or devour their souls.^[6]

One particular rhyme shows how the last child out on Nos Calan Gaeaf was at risk of being eaten by the fearsome beast:^[5]

The following morning, all the stones containing villagers' names would be checked, and finding one's stone burned clean was believed to be good luck. If, however, a stone was missing, the person who wrote their name on the absent stone would be believed to die within one year.^[5]

Harvest mare

Calan Gaeaf is a harvest festival and many games would be played involving the harvest. When the last corn stalk was harvested, workers would leave a few stalks uncut and then play a game with the uncut stalks to see who could reap them. Once the final corn stalks were cut, the stalks were twisted into something called a "harvest mare." The winner would stuff the harvest mare inside his clothing and try to sneak it into the house while the women worked on the feast.^{[7][better source needed]} If the reaper successfully got the harvest mare into the house, he was rewarded. If he was unsuccessful, he was mocked.^[8]

Feast

After the harvest was gathered and the livestock was slaughtered, a large feast would be held that was cooked by all the women in the village.^[9][8]

Seeing the future

• The boys were instructed to cut 10 leaves of ivy, throw one away and put the other nine under their pillows. Apparently, this allowed the boys to see the future, and if they touched the ivy then they could see witches while asleep.
• The girls were instructed to grow a rose in the shape of a large hoop, go through the circle three times prior to cutting a rose, and then place the rose under their pillow. This allowed the girls to see into the future.
• Unmarried women were instructed to darken their rooms during Nos Calan Gaeaf, and then an unmarried woman could look into the mirror to see the face of the future groom. If a skull appeared in the mirror, the unmarried woman was meant to die within the year. If a future groom could not be seen, unmarried women were instructed to peel an apple and throw the skin over their shoulders. Apparently, the shape the apple skin made would show the first initial of her future husband.^[9]
