Mārtiņi or Mārtiņdiena (Martin's Day) is the name of the festival in Latvia celebrated on November 10, marking the end of the fall and the beginning of winter. In ancient Latvia the festival marked the passage from Ūsiņš to Mārtiņš, two horse deities. Ūsiņš is invoked during the summer, while Mārtiņš 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. Mārtiņi also marked the beginning of masquerading and sledding, among other winter activities. Nowadays, Mārtiņi is commemorated by young people and rural Latvians as a way to be connected with Latvian traditions.
