At this point I shall say a few words about the religious beliefs of the Swedes. That nation has a magnificent temple, which is called Uppsala, located not far from the city of Sigtuna. In this temple, built entirely of gold, the people worship the statues of three gods. The mightiest of them, Thor, occupies a throne in the middle of the chamber; Odin and Freyr have places on either side. . . . Thor, they say, presides over the air and governs thunder and lightning, winds and rains, and fair weather for crops. Odin, that is, the Mad One, carries on war and gives men strength against their enemies. Freyr bestows peace and pleasure on mortals; his likeness they fashion with an immense phallus. Odin they sculpt armed, as the Romans represented Mars. Thor with his scepter resembles Jove, they say.
Near that temple is a very large tree with widespread branches which are always green both in winter and summer. What kind of tree it is nobody knows. There is also a spring there where the pagan are accustomed to perform sacrifices and to immerse a human being alive. As long as his body is not found, the request of the people will be fulfilled. A golden chain encircles that temple and hangs over the gables of the building.When the Swedes converted to Christianity, the Uppsala temple was destroyed and the sacred grove cut down. Their first bishop took his seat at Uppsala, building the country's first cathedral near the burial mounds of Sweden's pagan kings.
