English: The black bull's head, the supposed symbol of the Slavic Obotrites and their princes-chieftains in the form of a hypothetical flag or banner of arms. The black bull's head was later adopted by the dukes of Mecklenburg. According to some sources, the bull's head was also used by Redarians, one of the four major Lutician tribes, and associated with their main deity Swarożyc-Radegast. This picture was created based on Stemma degli Obodriti of armoriale.it, but the head is in black.
