One of the most iconic and enduring customs of Mārtiņi is the appearance of Mārtiņbērni—costumed mummers who travel from house to house, much like carolers or trick-or-treaters. Dressed as animals, spirits, or exaggerated characters from village life, they perform songs, dances, and humorous skits in exchange for food or drink. Their arrival is boisterous, playful, and symbolic: they represent the spirits of fertility, abundance, and transition, ensuring that each household remains protected and prosperous through the winter.
Masks were—and still are—a key part of the tradition. Often handmade from wood, straw, or fabric, they blur the line between human and spirit, allowing the wearer to embody forces greater than themselves. To open one’s door to the Mārtiņbērni is to welcome fortune, creativity, and a bit of controlled chaos into the home—a necessary disruption before the calm of winter.
