I looked: I saw an immense dust storm come from the north, an immense cloud with lightning flashing from it, a huge ball of fire glowing like bronze. Within the fire were what looked like four creatures vibrant with life. Each had the form of a human being, but each also had four faces and four wings. Their legs were as sturdy and straight as columns, but their feet were hoofed like those of a calf and sparkled from the fire like burnished bronze. On all four sides under their wings they had human hands. All four had both faces and wings, with the wings touching one another. They turned neither one way nor the other; they went straight forward.
