According to the Gesta Danorum, Alfhild,[a] daughter of the Geatish king Siward, was a shieldmaiden who had her own fleet of longships with crews of young female pirates and raided along the coasts of the Baltic Sea.
Alf and his Scanian comrade, Borgar, together with their Danish sea-warriors, searched for and eventually found Alfhild and her fleet by the coast of southern Finland.
Some years later, in a war fought against a revolting Danish clan, Alf and his brothers and their father king Sigar were killed.
The account in Saxo Grammaticus' Gesta Danorum[1] is the original story of Alf and Alfhild, based on one of the old folktales or songs he gathered for his work.
Italian poet Torquato Tasso writes his most famous tragedy on her story, called Il re Torrismondo, where Alvida is promised in marriage to the king of Sweden, Germondo, but falls in love with Torrismondo, so she decides to commit suicide in order not to choose between love and honor.
