m., gen. surts and surtar, [svartr], the Black, the name of a fire-giant, the world-destroyer, Vsp. 52, 54, Vþm. 17, 18; Surta(r)-logi, the flame of Surt, the last destruction of the world by fire, Vþm. 50: curious is the phrase, gott er þá á Gimli með Surti, Edda (Cod. Ups. ii. 292). surtar-brandr, m. ‘surts-brand,’ is the common Icel. word for jet, see Eggert Itin. The word is found on vellum MS. of Bret. (1849) 116, and is therefore old, and interesting because the name of the mythical fire-giant and destroyer is applied to the prehistoric fire as a kind of heathen geological term.
