[8] blôm eldi ‘blue fire’: The reference is probably to the blue flame emitted on combustion of sulphur. In a fragment of Barth extant in the mid-C13th Norwegian ms. AM 237 b fol (Loth 1969, 233), the phrase blár loge ‘blue flame’ is used to translate Lat. flamma sulphurea ‘sulphurous flame’ (cf. ONP: blár 3; Loth 1969, 221).
