The Mari Lwyd, meaning 'Gray Horse', is a Welsh tradition. Mari Lwyd would try and gain entry to houses via song. The accompanist would explain why they needed to enter and the occupant of the house would sing why they can't be let in. This would go back and forth until the occupant didn't have any more reasons to not let them in. When inside, Mari Lwyd and the accompanist would eat food and drink ale. When leaving the Mari Lwyd would wish everyone a Happy New Year.
To see the Mari Lwyd approaching a home, inn or pub is to be seen as good luck. Many owners still welcome the tradition, even though they initially have to deny her entry. It’s seen as a blessing to witness the movement and to be a part of the songs. She brings an air of optimism for a positive and fortuitous new year.
