"And the serpent cast out of his mouth, after the woman water as a river, that he might cause her to be carried away by the stream. And the earth helped the woman, and the earth opened her mouth, and swallowed up the river which the dragon cast out of his mouth."
This appears to be precisely the action which is presented to us in the three constellations of Andromeda, Cetus, and Eridanus. Andromeda is always shown as a woman in distress, and the Sea-monster, though placed far from her in the sky, has always been understood to be her persecutor. Thus Aratus writes—
"Andromeda, though far away she flies,
Dreads the Sea-monster, low in southern skies."
The latter, baffled in his pursuit of his victim, has cast the river, Eridanus, out of his mouth, which, flowing down below the southern horizon, is apparently swallowed up by the earth.
It need occasion no surprise that we should find imagery used by St. John in his prophecy already set forth in the constellations nearly 3,000 years before he wrote. Just as, in this same book, St. John repeated Daniel's vision of the fourth beast, and Ezekiel's vision of the living creatures, as he used the well-known details of the Jewish Temple, the candlesticks, the laver, the altar of incense, so he used a group of stellar figures perfectly well known at the time when he wrote. In so doing the beloved disciple only followed the example which his Master had already set him. For the imagery in the parables of our Lord is always drawn from scenes and objects known and familiar to all men.
In two instances in which leviathan is mentioned, a further expression is used which has a distinct astronomical bearing. In the passage already quoted, where Job curses the day of his birth, he desires that it may not "behold the eyelids of the morning." And in the grand description of leviathan, the crocodile, in chapter xli., we have—
"His neesings flash forth light,
And his eyes are like the eyelids of the morning."
Canon Driver considers this as an "allusion, probably to the reddish eyes of the crocodile, which are said to appear gleaming through the water before the head comes to the surface." This is because of the position of the eyes on the animal's head, not because they have any peculiar brilliancy.
"It is an idea exclusively Egyptian, and is another link in the chain of evidence which connects the author of the poem with Egypt. The crocodile's head is so formed that its highest points are the eyes; and when it rises obliquely to the surface the eyes are the first part of the whole animal to emerge. The Egyptians observing this, compared it to the sun rising out of the sea, and made it the hieroglyphic representative of the idea of sunrise. Thus Horus Apollo says: When the Egyptians represent the sunrise, they paint the eye of the crocodile, because it is first seen as that animal emerges from the water."[209:1]
In this likening of the eyes of the crocodile to the eyelids of the morning, we have the comparison of one natural object with another. Such comparison, when used in one way and for one purpose, is the essence of poetry; when used in another way and for another purpose, is the essence of science. Both poetry and science are opposed to myth, which is the confusion of natural with imaginary objects, the mistaking the one for the other.
