Reference has already been made to the gorgon in a quotation from Milton.
The name now denotes anything unusually hideous. In classic story there
were three gorgons, with serpents on their heads instead of hair. Medusa
was the chief of the three, and the only one that was mortal. So hideous
was her face that whoever set eyes on it was instantly turned to stone.
She was slain by Perseus, and her head placed upon _the shield of Minerva_
(termed the Ægis of Minerva). Homer, in the "Odyssey," Book xi. thus
alludes to the dread creature:
"Lest Gorgon rising from the infernal lakes
With horrors armed, and curls of hissing snakes,
Should fix me stiffened at the monstrous sight,
A stony image in eternal night."
And Shakespeare, in _Macbeth_, Act ii. sc. 3, uses the name to picture, in
a word, the horrible discovery of the murdered Duncan:
"Approach the chamber, and destroy your sight
With a new gorgon."
