[1, 2, 3, 4] ins gjalla baugnafaðs hjóls meyjar Hǫgna ‘the resounding boss-hubbed wheel of the maid of Hǫgni <legendary king> [= Hildr > SHIELD]’: This extended kenning, like that in st. 1, includes an adjectival element formed from a p. p., baugnafaðr ‘boss-hubbed’ (from baugr ‘boss, circle’ and nǫf ‘nave, hub’), that both continues and draws attention to the analogy between a shield and a wheel that forms the basis of the kenning. This adj. is a hap. leg. and caused the scribes difficulty. A second adj., gjallr ‘ringing, resounding’, has a similar effect, as it can apply both to the noise of a cart-wheel turning and the striking of weapons on the metal boss of a wooden shield. Hǫgni was the father of Hildr, a valkyrie-like figure central to the story of the Everlasting Battle (Hjaðningavíg) that forms the subject of Rdr 9-12 (q. v.). In skaldic poetry Hildr may be a proper name (and thus the basis of a woman- or valkyrie-kenning), but carries with it some semantic resonance from its meaning as the common noun hildr ‘battle’.
