Ezekiel makes reference to "ring" and "wheel" symbols. In his vision he saw "one wheel upon the earth by the living creatures, with his four faces. The appearance of the wheels and their work was like unto the colour of beryl; and they four had one likeness; and their appearance and their work was as it were a wheel in the middle of a wheel.... As for their rings, they were so high that they were dreadful; and their rings were full of eyes round about them four. And when the living creatures went, the wheels went by them; and when the living creatures were lifted up from the earth, the wheels were lifted up. Whithersoever the spirit was to go, they went, thither was their spirit to go; and the wheels were lifted up over against them; _for the spirit of the living creature was in the wheels_....[388] And the likeness of the firmament upon the heads of the living creature was as the colour of terrible crystal, stretched forth over their heads above.... And when they went I heard the noise of their wings, like the noise of great waters, as the voice of the Almighty, the voice of speech, as the noise of an host; when they stood they let down their wings...."[389] Another description of the cherubs states: "Their whole body, and their backs, and their hands, and their wings, and the wheels, were full of eyes (? stars) round about, even the wheels that they four had. As for the wheels, it was cried unto them in my hearing, O wheel!"--or, according to a marginal rendering, "they were called in my hearing, wheel, or Gilgal," i.e. move round.... "And the cherubims were lifted up."[390] It would appear that the wheel (or hoop, a variant rendering) was a symbol of life, and that the Assyrian feather-robed figure which it enclosed was a god, not of war only, but also of fertility. His trident-headed arrow resembles, as has been suggested, a lightning symbol. Ezekiel's references are suggestive in this connection. When the cherubs "ran and returned" they had "the appearance of a flash of lightning", and "the noise of their wings" resembled "the noise of great waters". Their bodies were "like burning coals of fire". Fertility gods were associated with fire, lightning, and water. Agni of India, Sandan of Asia Minor, and Melkarth of Phoenicia were highly developed fire gods of fertility. The fire cult was also represented in Sumeria (pp. 49-51).
