Biblical descriptions of the different angel classes can get rather wild indeed. Like the cherubim: "Cherubim have four faces: one of a man, an ox, a lion, and an eagle (later adopted as the symbols of the four evangelists). They have four conjoined wings covered with eyes (although Revelation 4:8 appears to describe them with six wings like the seraphim), a lion's body, and the feet of oxen." Or the aforementioned wheels, which are apparently called ophanim: "They appear as a beryl-coloured wheel-within-a-wheel, their rims covered with hundreds of eyes. "
