The mysterious biblical book of Ezekiel, with its enigmatic visions, has mystified millions since it was composed. In his account, the heavens open, and Ezekiel sees "visions of God." The word and hand of the Lord are upon the prophet, who recounts at 1:4-6:
As I looked, behold, a stormy wind came out of the north, and a great cloud, with brightness round about it, and fire flashing forth continually, and in the midst of the fire, as it were gleaming bronze.
And from the midst of it came the likeness of four living creatures. And this was their appearance: they had the form of men, but each had four faces, and each of them had four wings.
Ezekiel's "four living creatures" are described as having the faces of a man, lion, ox and eagle (1:10ff):
As for the likeness of their faces, each had the face of a man in front; the four had the face of a lion on the right side, the four had the face of an ox on the left side, and the four had the face of an eagle at the back....
As for the appearance of the wheels and their construction: their appearance was like the gleaming of a chrysolite; and the four had the same likeness, their construction being as it were a wheel within a wheel.
To this day, much speculation is bandied about as to what his "wheel within a wheel" with the merkabah or chariot and four-faced creatures truly signify. Some have claimed that this bizarre description represents a "spacecraft" and that Yahweh is an "alien."
However, scrutinizing the text and placing it in the context of its milieu reveals that Ezekiel's vision was of the zodiac, with Yahweh as the typical sun god in his chariot, surrounded by the four fixed signs representing the equinoxes and solstices.
