Myths of the Norsemen From the Eddas and Sagas

Nevertheless, he assembled the people near Thor’s statue, and after secretly bidding his principal attendant to smash the idol with his battle-axe if the people turned their eyes away but for a moment, he began to address them. Suddenly, while all were listening to him, Olaf pointed to the horizon, where the sun was slowly breaking its way through the clouds, and exclaimed, “Behold our God!” The people one and all turned to see what he meant, and the attendant seized this opportunity for attacking the idol, which yielded easily to his blows, and a host of mice and other vermin scattered hastily from its hollow interior. Seeing now that the food placed before their god had been devoured by noxious animals only, the people ceased to revere Thor, and definitely accepted the faith which King Olaf had so long and vainly pressed upon them. 
Chapter V: Tyr
The God of War
Tyr Tiu, or Ziu was the son of Odin, and, according to different mythologists, his mother was Frigga, queen of the gods, or a beautiful giantess whose name is unknown, but who was a personification of the raging sea. He is the god of martial honour, and one of the twelve principal deities of Asgard. Although he appears to have had no special dwelling there, he was always welcome to Vingolf or Valhalla, and occupied one of the twelve thrones in the great council hall of Glads-heim.
