The arms of Stephen as King of England. These show two golden lions with blue tongues and claws in the pose known as “passsant gaurdant” on a red field. At this date heraldry was being codified and systemised as knights used emblems on their shields to identify themselves in battle. Earlier kings had used two lions in a variety of poses and colours. The familiar third lion was added by King Richard I in about 1095.
