Curdie was the son of Peter the miner. He lived with his father and mother in a cottage built on a mountain, and he worked with his father inside the mountain. A mountain is a strange and awful thing. In old times, without knowing so much of their strangeness and awfulness as we do, people were yet more afraid of mountains. But then somehow they had not come to see how beautiful they are as well as awful, and they hated them-and what people hate they must fear. Now that we have learned to look at them with admiration, perhaps we do not feel quite awe enough of them. To me they are beautiful terrors.
