In ancient Latvia
was the name of a festival, celebrated on November 10
, marking the end of the fall and the beginning of winter. The festival marks the transfer from Usins
, two deities of horses. Usins is invoked during the summer, while Martins is a winter god. The festival marked the end of the preparations for winter, such as salting meat and fish, storing the harvest and making preserves. Martini also marked the beginning of masquerading and sledding, among other wintry activities.
