"Now in turn Athene, daughter of Zeus of the aegis, beside the threshold of her father slipped off her elaborate
dress which she herself had wrought with her hands' patience, and now assuming the war tunic of Zeus who gathers
the clouds, she armed in her gear for the dismal fighting.
And across her shoulders she threw the betasselled, a terrible
aegis, all about which Terror hands 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.
he took up the man-enclosing elaborate start shield,
a thing of splendour. There were ten circles of bronze upon up,
and set about it were twenty knobs of tin, pale-shining,
and in the very centre another knob of dark cobalt.
And circled in the midst of all was the blank-eyed face of the Gorgon
with her stare of horror, and Fear was inscribed upon it, and Terror.
The strap of the shield has silver upon it, and there also on it
was coiled a cobalt snake, and there were three heads upon him
twisted to look backward and grown from a single neck, all three."
— Homer, The Iliad
