From the court of Gloriana, Queen of Faery, the gallant Sir Guyon
sets out on adventure bent, and with him is a holy Palmer, or
pilgrim, to protect him from the evil that lurks by every wayside.
Hardly have the two entered the first wood when they fall into the
hands of the wicked Archimago, who spends his time in devising
spells or enchantments for the purpose of leading honest folk
astray.

For all he did was to deceive good knights,
And draw them from pursuit of praise and fame.

Escaping from the snare, Guyon hears a lamentation, and turns aside
to find a beautiful woman dying beside a dead knight. Her story is,
that her man has been led astray by the Lady Acrasia, who leads
many knights to her Bower of Bliss, and there makes them forget
honor and knightly duty. Guyon vows to right this wrong, and
proceeds on the adventure.

With the Palmer and a boatman he embarks in a skiff and crosses the
Gulf of Greediness, deadly whirlpools on one side, and on the other
the Magnet Mountain with wrecks of ships strewed about its foot.
Sighting the fair Wandering Isles, he attempts to land, attracted
here by a beautiful damsel, there by a woman in distress; but the
Palmer tells him that these seeming women are evil shadows placed
there to lead men astray. Next he meets the monsters of the deep,
"sea-shouldering whales," "scolopendras," "grisly wassermans,"
"mighty monoceroses with unmeasured tails." Escaping these, he
meets a greater peril in the mermaids, who sing to him alluringly:

This is port of rest from troublous toil,
