In Germanic mythology, Thor is a hammer-wielding god associated with lightning, thunder, storms, sacred groves and trees, strength, the protection of mankind and also hallowing and fertility. Besides Old Norse Þórr, the deity occurs in Old English as Þunor, in Old Frisian as Thuner, in Old Saxon as Thunar, and in Old High German as Donar, all ultimately stemming from the Common Germanic theonym *Þunraz, meaning 'thunder'.
