Equestrian seal

An equestrian seal is a type of seal used in the European Middle Ages, characterized by the depiction of the owner as a mounted warrior in full armour. Originating in the high medieval period (late 11th to early 12th century), the type was frequently used throughout the 13th to 14th centuries. Continued use into the 15th and 16th centuries was mostly limited to high nobility, especially royalty, while lower nobility switched to the use of simple heraldic seals.
