In the Icelandic Völsunga saga, Sigurd’s horse is named Grani.
Grani is a powerful gray horse descended from Odin’s eight-legged steed, Sleipnir. Sigurd receives him after choosing from a herd, and the horse proves worthy of the hero’s legendary status. The saga emphasizes that Grani is not merely a means of transport: he shares in Sigurd’s adventures and is strong enough to carry the immense treasure taken from the dragon Fáfnir.
Readers sometimes confuse Grani with Sleipnir because both horses belong to the same mythic lineage. Sleipnir is Odin’s supernatural mount, while Grani is the horse associated specifically with Sigurd in the Völsung tradition. Grani also appears in later retellings of the legend, including versions connected with Wagner’s Ring cycle, although Wagner changes several names and relationships.
The Völsunga saga was written in medieval Iceland and preserves stories about the Völsung family, Sigurd, the dragon Fáfnir, and the cursed treasure that drives the tragedy.
