The shepherds then answered, "Did you not see a little below these mountains a stile that led into a meadow on the left hand side of this way?" They answered, "Yes." Then said the shepherds, "From that stile there goes a path that leads directly to Doubting Castle, which is kept by Giant Despair; and these men" (pointing to them among the tombs) "came once on pilgrimage, as you do now, even until they came to that same stile. And because the right way was rough in that place, they chose to go out of it into that meadow, and there were taken by Giant Despair, and cast into Doubting Castle, where, after they had been kept a while in the dungeon, he at last did put out their eyes, and led them among those tombs, where he has left them to wander to this very day, that the saying of the Wise Man might be fulfilled, 'He that wandereth out of the way of knowledge, shall remain in the congregation of the dead.'" Then Christian and Hopeful looked upon one another with tears gushing out, but yet said nothing to the shepherds. Then I saw in my dream, that the shepherds had them to another place in a bottom, where was a door on the side of a hill; and they opened the door, and bid them look in. They looked in, therefore, and saw that within it was very dark and smoky; they also thought that they heard there a rumbling noise, as of fire, and a cry of some tormented, and that they smelt the scent of brimstone. Then said Christian, "What means this?" The shepherds told them, "This is a by-way to hell, a way that hypocrites go in at: namely, such as sell their birthright, with Esau; such as sell their master, with Judas; such as blaspheme the Gospel, with Alexander; and that lie and deceive with Ananias and Sapphira his wife." HOPE. Then said Hopeful to the shepherds, "I perceive that these had on them, even every one, a show of pilgrimage, as we have now; had they not?" SHEP. Yes, and held it a long time too. HOPE. How far might they go on in pilgrimage in their day, since they notwithstanding were thus miserably cast away? SHEP. Some farther, and some not so far as these mountains. Then said the pilgrims one to another, "We have need to cry to the Strong for strength." SHEP. Ay, and you will have need to use it when you have it, too. [Sidenote: GATE OF THE CELESTIAL CITY] By this time the pilgrims had a desire to go forward, and the shepherds a desire they should; so they walked together towards the end of the mountains. Then said the shepherds one to another, "Let us here show to the pilgrims the gate of the Celestial City, if they have skill to look through our perspective glass."[6] The pilgrims then lovingly accepted the motion; so they had them to the top of a high hill called Clear, and gave them their glass to look. [6] "Perspective glass" is an old name for a telescope or spy-glass.
