I looked up and saw a windstorm coming from the north. Lightning was flashing from a huge cloud, and the sky around it was glowing. Where the lightning was flashing, something shone like bronze. At the center of the storm I saw what looked like four living creatures in human form, but each of them had four faces and four wings. Their legs were straight, and they had hoofs like those of a bull. They shone like polished bronze. In addition to their four faces and four wings, they each had four human hands, one under each wing. Two wings of each creature were spread out so that the creatures formed a square, with their wing tips touching. When they moved, they moved as a group without turning their bodies.
