Bicycle

Huginn: It was slim, and of an alloy I had only seen once before. It had wheels, and wheels within wheels, and men feared its coming.

Muninn: If I had not known what you had seen, I would have thought you had seen the wrath of God, whose mills grind slow but exceedingly fine.

H: These wheels were exceedingly fast. And upon them was a man, whose head was as that of an eagle.

M: No doubt. But it was only a bicycle, a velocipede, a machine for magnifying and harnessing the muscles of the human leg.

H: Non-polluting. Non-blaspheming. Non-magical. Two major wheels, a model of what is, in earth and heaven.

M: Go to, old man. You have heard enough.
