Traditionally, people avoid churchyards, stiles, and crossroads, since spirits are thought to gather there.
[4] 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.
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.
[8] 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.
