A famed knight from the city of Kesarija in the Serbo-Russian Povest’ o Tryshchane.
His famous brothers were Igurn and Marko.
He hadn’t lifted a lance in forty years when Lancelot and Tristan visited his city and demanded to sleep with his wife, Cvitazija, but he dutifully saddled up, swiftly defeated both knights at the same time, and let them go after slapping them each across the face.
