A winged helmet is a helmet decorated with wings, usually one on each side. Ancient depictions of the god Hermes, Mercury and of Roma depict them wearing winged helmets, and in the 19th century the winged helmet became widely used to depict the Celts. It was also used in romantic illustrations of legendary Norse gods and heroes. The motif, along with the horned helmet, became a clichéd signifier of the Northern warrior.
