Thor (from Old Norse: Þórr) is a prominent god in Germanic paganism. In Norse mythology, he is a hammer-wielding god associated with thunder, storms, strength, protection, fertility, farmers, and free people. Besides Old Norse Þórr, the deity occurs in Old English as Thunor, in Old Frisian as Thuner, in Old Saxon as Thunar, and in Old High German as Donar, all ultimately stemming from the Proto-Germanic theonym *Þun(a)raz, meaning 'Thunder'.

Thor is a prominently mentioned god throughout the recorded history of the Germanic peoples, from the Roman occupation of regions of Germania, to the Germanic expansions of the Migration Period, to his high popularity during the Viking Age, when, in the face of the process of the Christianization of Scandinavia, emblems of his hammer, Mjölnir, were worn and Norse pagan personal names containing the name of the god bear witness to his popularity.

Blood brother can refer to two or more people not related by birth who have sworn loyalty to each other. This is in modern times usually done in a ceremony, known as a blood oath, where each person makes a small cut, usually on a finger, hand, or the forearm, and then the two cuts are pressed together and bound, the symbolism being that each person's blood now flows in the other participant's veins.

The act carries a risk due to blood-borne diseases. The process usually provides a participant with a heightened symbolic sense of attachment with the other participant.

Thor's Fight with the Giants (Swedish: Tors strid med jättarna) is an 1872 painting by the Swedish artist Mårten Eskil Winge. It depicts the Norse god Thor in a battle against the jötnar. The thunder god rides his chariot pulled by the goats Tanngrisnir and Tanngnjóstr, wears his belt Megingjörð, and swings his hammer Mjölnir, which is wreathed in lightning. The painting was made using oil on canvas, has the dimensions 484 x 333 centimeters, and belongs to Nationalmuseum in Stockholm.

Fyrisvellir, Fyris Wolds, or Fyrisvallarna, was the marshy plain (vellir) south of Gamla Uppsala where travellers had to leave the ships on the river Fyris (Fyrisån) and walk to the Temple at Uppsala and the hall of the Swedish king.

Sigyn (Old Norse "(woman) friend of victory") is a deity from Norse mythology. She is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In the Poetic Edda, little information is provided about Sigyn other than her role in assisting her husband Loki during his captivity. In the Prose Edda, her role in helping Loki through his time spent in bondage is reiterated, she appears in various kennings, and her status as a goddess is mentioned twice. Sigyn may appear on the Gosforth Cross and has been the subject of an amount of theory and cultural references.
