Question

Which symbol was on Arthur's coat of arms?

Answer 1

In a manuscript from the later 13th century, Arthur's shield has three gold leopards, a likely heraldic flattery of Edward I of England (Brault, 22). Geoffrey of Monmouth assigned Arthur a dragon on his helmet and standard, which is possibly canting arms on Arthur's father's name, Uther Pendragon (Brault, 23).
