“Hrungnir had the heart which is no- torious, of hard stone and spiked with three corners, even as the written character is since formed, which men call Hrungnir's Heart. His head also was of stone; his shield too was stone, wide and thick, and he had the shield before him when he stood at Grjotunagard and waited for Thor. Moreover he had a hone for a weapon, and brandished it over his shoulders, and he was not a pretty sight.”
