Heiðr

Heiðr (from the Old Norse adjective meaning "bright" or the noun meaning "honour") is the seeress and witch (völva) mentioned in one stanza of Völuspá, related to the story of the Æsir-Vanir war:

Heith they named her

who sought their home,

The wide-seeing witch,

in magic wise;

Minds she bewitched

that were moved by her magic,

To evil women

a joy she was.

—Völuspá (22), Bellows’ translation

The general assumption is that Heiðr is an alternate name for the witch Gullveig, mentioned in the previous stanza, who, in turn, is often thought to be a hypostasis of Freyja. But it is sometimes argued that the völva who recites the poem refers to herself.

Heiðr is also a seeress in several works such as Landnámabók (S 179 / H 45), Hrólfs saga kraka (3) and Örvar-Odds saga (2), where she predicts Örvar's death.

Heiðr is lastly a child of the giant Hrímnir according to Völuspá hin skamma (Hyndluljóð, 32).
