Raven banner
The raven banner (Old Norse: hrafnsmerki [ˈhrɑvnsˌmerke]; Middle English: hravenlandeye) was a flag, possibly totemic in nature, flown by various Viking chieftains and other Scandinavian rulers during the 9th, 10th and 11th centuries. Period description simply describes it as a war banner with a raven mark on it, although no complete visual description or depiction of the raven banner is known from the time.
