Fire is periphrased as brother of the wind and of Ægir, bane of wood and houses, Hálfr's bane and 'sun of the houses'.
Hvernig skal kenna eld? Svá, at kalla hann bróður vinds ok Ægis, bana ok grand viðar ok húsa, Hálfs bani, sól húsanna.
How shall fire be periphrased? Thus: by calling it brother of the wind and of Ægir, bane and destroyer of wood and houses, Hálfr's bane, sun of the houses.
