The Gosforth Cross is a large stone monument in St Mary's churchyard at Gosforth in the English county of Cumbria, dating to the first half of the 10th century AD. Formerly part of the kingdom of Northumbria, the area was settled by Scandinavians some time in either the 9th or 10th century. It has gained reputation for its combination of Christian symbols with Nordic symbols, being a tangible piece of evidence of the impact of the Christianization of Scandinavia. The Gosforth Cross has elaborate carvings which have been interpreted as representing characters and scenes from Norse mythology, similarly to how the Jelling stones in Denmark depict Jesus with other Norse mythological characters. Its design is modelled after the cross design that originated during the Christianization of Ireland. The Gosforth Cross was first identified in 1886 by the amateur antiquarian Charles Arundel Parker in his book The Ancient Crosses at Gosford and Cumberland. He demonstrated that the cross showed scenes described in the Poetic Edda. Those include images identified as: Loki bound with his wife Sigyn protecting him. The god Heimdallr holding his horn. The god Víðarr tearing the jaws of Fenrir. Thor's failed attempt to catch Jörmungandr, the Midgard Serpent. It is currently debated amongst scholars whether the sources were added to the Cross out of reverence for Viking beliefs and still clinging to their own identity or as a way to parallel Norse mythology (i.e. Ragnarök, the death of Baldr) with Christian beliefs (i.e. the Apocalypse, the crucifixion of Christ). Among the parallels is Loki being bound is allegorical for Satan being bound, the death of Baldr accompanied by Hod and Nanna interchangeable with Christ's death as witnessed by Longinius and Mary Magdalene, and the battle Odin has with Surtr similar to how Christ ultimately conquers the Devil. Another is how the base of the cross has a tree-like design, looking like bark. This is a possible parallel between Yggsdrasil and the Tree of Life; both featured heavily in their respective mythologies.
