Unaós, the outermost farm in Hjaltastaðarþinghá settlement, at the mouth of the Selfljót river, named for Uni Garðarsson the Dane. Uni was the son of Garðar Svavarsson, who discovered Iceland and called it Garðarshólmi (“Garðar’s isle”). Harold Fairhair king of Norway sent Uni to Iceland to colonise it, for which he was to receive an earldom. From there he went south along the east of Iceland, staying with Úlfljótur in Skaftafell County. Úlfljótur slew Uni at his second attempt to escape after having got his host´s daughter with child. Therefore this first attempt of a Nor­we­g­ian king to seize Iceland failed because Uni was slain by Ice­land­ers.
