which was Error; it was steep on the far off side, and they bade
them look down to the foot of it. So Christian and Hopeful cast
their eyes down, and saw there some men who had lost their lives
by a fall from the top; men who had been made to err, for they
had put their trust in false guides.

Have you not heard of them? said the men.

Christian.--Yes, I have.

Men.--These are they, and to this day they have not been put in a
tomb, but are left here to warn men to take good heed how they
come too near the brink of this hill.

Then I saw that they had led them to the top of Mount Caution,
and bade them look far off. From that stile, said they, there
goes a path to Doubting Castle, which is kept by Giant Despair,
and the men whom you see there came as you do now, till they got
up to that stile; and, as the right way was rough to walk in,
they chose to go through a field, and there Giant Despair took
them, and shut them up in Doubting Castle, where they were kept
in a den for a while, till he at last sent them out quite blind,
and there they are still. At this Christian gave a look at
Hopeful, and they both burst out with sobs and tears, but yet
said not a word.

Then the four men took them up a high hill, the name of which was
Clear, that they might see the gates of The Celestial City, with
the aid of a glass to look through, but their hands shook, so
they could not see well.
