monsters whose head Perseus could possibly cut off. As for the other
two, let him have the sharpest sword that ever was forged, and he might
have hacked away by the hour together, without doing there the least
harm.

"Be cautious," said the calm voice which had before spoken to him. "One
of the Gorgons is stirring in her sleep, and is just about to turn over.
That is Medusa. Do not look at her! The sight would turn you to stone!
Look at the reflection of her face and figure in the bright mirror of
your shield."

Perseus now understood Quicksilver's motive for so earnestly exhorting
him to polish his shield. In its surface he could safely look at the
reflection of the Gorgon's face. And there it was,--that terrible
countenance,--mirrored in the brightness of the shield, with the
moonlight falling over it, and displaying all its horror. The snakes,
whose venomous natures could not altogether sleep, kept twisting
themselves over the forehead. It was the fiercest and most horrible
face that ever was seen or imagined, and yet with a strange, fearful,
and savage kind of beauty in it. The eyes were closed, and the Gorgon
was still in a deep slumber; but there was an unquiet expression
disturbing her features, as if the monster was troubled with an ugly
dream. She gnashed her white tusks, and dug into the sand with her
brazen claws.

The snakes, too, seemed to feel Medusa's dream, and to be made more
restless by it. They twined themselves into tumultuous knots, writhed
fiercely, and uplifted a hundred hissing heads, without opening their
eyes.
