Thor, in Norse mythology, is a hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, the protection of mankind, and also hallowing and fertility. He is prominently mentioned throughout the recorded history of the Germanic peoples and is described as relentlessly slaughtering his foes and having fierce battles with the monstrous serpent Jörmungandr. Symbols of Thor were worn in defiance during the Christianization of Scandinavia, and today his influence is found in the names of cities and a day of the week as well as popular culture. He is shown here in Thor's Fight with the Giants, an 1872 painting by Mårten Eskil Winge which depicts the deity in battle with a jötunn.Painting: Mårten Eskil Winge
