Hárbarðsljóð[1] (Old Norse: 'The Lay of Hárbarðr')[2] is one of the poems of the Poetic Edda, found in the Codex Regius and AM 748 I 4to manuscripts.
The ferryman Hárbarðr (Greybeard) is rude and obnoxious towards Thor who is returning to Asgard after a journey in Jötunheimr, the land of the jötnar.
In the last decade, several scholars have concluded that the poem is an intentionally stylized version of the traditional flyting structure.
Although the name Hárbarð means "Grey beard," in the opening exchange of insults Thor addresses the ferryman as one would speak to a youthful servant.
Loki in Lokasenna and Hárbarð in Hárbarðsljóð both accuse Thor's wife Sif of adultery, a charge that is never denied and may have been commonly known.
