Tyr was the Nordic god of war, a son of Odin and one of the twelve gods of Asgard. Tuesday was named after him, as another variant of his name was Tiu.

Tyr had but one hand, as he lost his right hand to a wolf called Fenris, one of Loki's children, but he killed his enemies with his left hand with an equal success.
