[5] hǫlfu hæra ‘twice as high’: The normal sense of hǫlfu, despite its literal sense ‘higher by half’. The comp. has nothing obvious to compare with, and may be simply an intensive, unless Bjarni Aðalbjarnarson’s theory about af hróka landi is correct (see Note to l. 1 above), or Finnur Jónsson’s suggestion that hǫlfu hæra means that the flame was twice the height of the burning building itself (Hkr 1893-1901, IV, 200).
