Hati's surname is Hróðvitnisson, attested in both Grímnismál and Gylfaginning, which indicates that he is the son of Fenrir, whose alternate name is Hróðvitnir ("Famous Wolf"). Hati's mother is the giantess, not named but mentioned in Völuspá and Gylfaginning, who dwells to the east of Midgard in the forest of Járnviðr ("Ironwood"). Snorri Sturluson states that this giantess and witch bears many giants for sons, all in the form of wolves including one named Mánagarm ("Moon Hound") who shall swallow the Moon and is thus identified with Hati. From this passage it is also presumed that Sköll is Hati's brother. Hati is the god of solar eclipses as well.
