[1] Heiðrún: The mythical she-goat that stands on the roof of Valhǫll and from whose udder the mead of the gods flows (see Grí 25, Hyndl 46/8, 47/8 and Gylf, SnE 2005, 33). The meaning of the cpd depends on the interpretation of the first element heið- (cf. the adj. heiðr ‘bright’ and the nouns heiðr m. ‘honour’ and heiðr f. ‘heath’). In this cpd name, heið- has been interpreted as a ritual word for mead used during sacrifice, i.e. heið ‘shining mead’ (see Höckert 1926-30, I, 53-4 and ARG II, 384). Cf. also the pers. n. Heiðdraupnir in Sigrdr 13/9. The second element, ‑rún f. ‘secret, hidden lore, mystery’, is frequently found as a part of f. personal names (cf. the Frankish f. pers. n. Chaiderūna). See also haidʀrūnō f. gen pl. ‘of shining runes’ in the Björketorp inscription (Run S Blekinge 1/1VI (KJ97)). Heiðrún does not occur in skaldic verse.
