Wynebgwrthucher

Wynebgwrthucher was the name given to King Arthur's shield in the 11th century Welsh prose work, Culhwch and Olwen. The shield and Arthur’s weapons are named when Arthur says to Culhwch:

You shall have the request that head and tongue name, as far as the wind dries, as far as the rain wets, as far as the sun rises, as far as the sea stretches, as far as the earth extends, excepting only my ship, my mantle, my sword Caledfwlch, my spear Rhongomyniad, my shield Wynebgwrthucher, my knife Carnwennan and my wife Gwenhwyvar.
