Fjölvar is a being inNorse mythology, possibly ajötunn, with whomOdin spends time fighting and seducing women with on the island of Algrœn ("All-green").[1][2]
Fjölvar is anOld Norse name still used today; it was used in Old Norse as an adjective meaning 'very wary, very cautious'.[3][4]
Fjölvar is only attested once inHárbardsljód (The lay of Hárbarð), which tells of Hárbarð (the god Odin in disguise) spending time with Fjölvar on the island of Algrœn ("All-green").[5]
I [Odin] was with Fjölvar all of five winters [five years],
In that island, which is called Algrœn [All-green];
We could fight and fell carrion,
To test much, to try our luck with a maiden.
— Hárbardsljód, 17, trans.J. Lindow, 2002.
This episode was recounted by Odin himself who alone slept with seven sisters on Algrœn in the poemHárbardsljód(18), written in the 13th century and included in thePoetic Edda.[1]
According to scholarJohn Lindow, since theþulur list Fjölvör among thejötnar, it is likely that Fjölvar would have been her male counterpart, and therefore also a jötunn.[1]
