11066 Sigurd           Discovered 1992 Feb. 9 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Sigurd was the most famous of all Norse heroes and played the principal part in the Volsungasaga. He rides through a ring of fire to awaken Brynhild twice, once for himself and once for the king Gunnar, in a complicated tale of love and deception and treachery.
