"I was in a Printing house in Hell & saw the method in which knowledge is transmitted from generation to generation.
In the first chamber was a Dragon-Man, clearing away the rubbish from a cave's mouth; within, a number of Dragons were hollowing the cave.
In the second chamber was a Viper folding round the rock & the cave, and others adorning it with gold silver and precious stones.
In the third chamber was an Eagle with wings and feathers of air: he caused the inside of the cave to be infinite, around were numbers of Eagle like men, who built palaces in the immense cliffs."
