It is customary also to solemnize in Uppsala, at nine-year intervals, a general feast of all the provinces of Sweden. From attendance at this festival no one is exempted Kings and people all and singly send their gifts to Uppsala and, what is more distressing than any kind of punishment, those who have already adopted Christianity redeem themselves through these ceremonies. The sacrifice is of this nature: of every living thing that is male, they offer nine heads with the blood of which it is customary to placate gods of this sort. The bodies they hang in the sacred grove that adjoins the temple. Now this grove is so sacred in the eyes of the heathen that each and every tree in it is believed divine because of the death or putrefaction of the victims. Even dogs and horses hang there with men. A Christian told me that he had seen 72 bodies suspended promiscuously. Furthermore, the incantations customarily chanted in the ritual of a sacrifice of this kind are manifold and unseemly; therefore, it is better to keep silent about them.
