Gražiškiai, Lithuania

The Dance of Šyvis (Lithuanian: Šyvio šokdinimas) is a celebration resembling a carnival of Užgavėnės, during which a group of masqueraders led by Šyvis (white horse) visits the homesteads of the town and surrounding villages to wish their hosts a good year. The tradition, which may have originated in Prussia, is celebrated only in Gražiškiai. The first mention of the Dance of Šyvis was in 18th-century written sources. In the past, this custom was practised in many villages in south-western Lithuania, but only in Gražiškiai has it survived to this day. The Dance of Šyvis is depicted in the town's coat of arms.
