One goddess you should never cross, quick to rouse to wrath and terrible in her exactions. Divinely, drop-dead gorgeous, of course.
There are several heart- prefixed triologisms in Homer, emphasizing the human pain, terror and sorrow of war and hostility; see, for example, Hector’s description of the hatred between him and Ajax.
Here the effect is of freezing the heart; compare Charlotte Bronte’s equally frozen reaction.
‘And across her shoulders she threw the betassled, terrible
aegis, all about which Terror hangs like a garland,
and Hatred is there, and Battle Strength, and heart-freezing Onslaught
and thereon is set the head of the grim gigantic Gorgon,
a thing of fear and horror, portent of Zeus of the aegis.’
