I saw a windstorm blowing in from the north. Lightning flashed from a huge cloud and lit up the whole sky with a dazzling brightness. The fiery center of the cloud was as shiny as polished metal, and in that center I saw what looked like four living creatures. They were somewhat like humans, except that each one had four faces and four wings. Their legs were straight, but their feet looked like the hoofs of calves and sparkled like bronze. Under each of their wings, these creatures had a human hand. The four creatures were standing back to back with the tips of their wings touching. They moved together in every direction, without turning their bodies.
