Did you know?

A ballista (a large missile-thrower in the form of a crossbow) that defended Windsor Castle in the 14th century was named in Latin Domina Gunilda, or “Lady Gunilda.” Gunilda is an Old Norse name and is a compound of gunnr and hildr, both words meaning “battle.” The English may have learned the name from early Norsemen who knew its etymological significance, or its use by the English may have been a coincidence. However, the use of this name for the Windsor ballista was not an isolated incident. Gonnylyde was the name of a cannon in a 14th century song. Our word gun, which also traces back to the 14th century, is probably a shortening of Gunilda.
