"One way leads to sea jutting boulders
where break the roaring waves of dark-eyed Amphitrite.
The other sets a perilous course between two cliffs,
one a sharp-topped mountain, so high in the heavens
that never dispersing black clouds surround it.
Shrouded in summer and autumn, the smooth peak is unclimbable,
and on the other side, there a dark ominous cave."
Homer, The Odyssey, Book XII
