Hildisvini

Hildisvíni is in Norse mythology, is a large boar (literally "battle boar") that the goddess Freya uses from time to time as a mount, as she usually uses a chariot pulled by cats.

Hildisvíni is also the name of King Áli's helmet, taken from rival King Adils following the ice battle at Lake Vänern: on that helmet is effigy of a boar, which, according to the Beowulf saga, would act as a guardian to the warrior wearing it.

Among the Old Norse, the boar was considered an omen for protection and a symbol of fertility.
