Atle Mjove

Atli the Slender (Old Norse: Atli hinn Mjovi) was a ninth-century Norwegian jarl mentioned in several Old Norse sources, including Heimskringla and Egils saga.

Atli was the son of Hundolf, a jarl of Gaular in Fjordane. His sister was Solvor Hundolfsdottir, the wife of King Harald Goldbeard of Sogn. He became friends with King Halfdan the Black of Vestfold and accompanied him on a number of his expeditions. In particular, Atli accompanied Halfdan when, following the death of Halfdan's father in law Harald Goldbeard and Halfdan's son Harald, the Vestfolder king led an expedition to take possession of Sogn as their heir. Halfdan made Atli jarl over all of Sogn.

Atli continued to govern Sogn into the reign of Halfdan's son Harald Fairhair. He is mentioned in Egils saga in connection with the famous skald Olvir Hnufa, the eponymous Egill's great-uncle. At a thing in Gaular, Olvir fell in love with Solveig Atladottir, Atli's daughter. The jarl refused Olvir permission to marry the girl, but he was so smitten that he abandoned his Viking life to be near her. A skald of some talent, he composed a number of love poems for Solveig. For reasons not revealed in the saga, but probably related to his courtship of Solveig, Olvir was attacked and nearly killed in his home by Solveig's brothers shortly after King Harald's conquest of Møre.

Atli's sons, Hallstein, Holmstein and Herstein, were famous Norsemen who sailed with the foster brothers Hjörleifr Hróðmarsson and Ingólfr Arnarson. They fell out, however, over Ingolfur's sister Helga, who married Hjörleifur. In the ensuing blood feud two of Atli's sons were killed and their erstwhile allies fled Norway for Iceland, becoming the first permanent settlers there.
