About Călușari
The Călușari (Romanian: Călușarii, Romanian pronunciation: [kəluˈʃarʲ]; singular: Călușar) are the participants to an old traditional Romanian dance known as the căluș. "Căluș" translates to horse, but in an endearing form. From three weeks after Easter until Pentecost, called Rusalii in Romanian, for around two weeks they have traditionally travelled to all their local communities where they would dance, accompanied by a few fiddlers.
