“Among the traditions concerning his birth is one related by Ælian (Historia Animalium, XII, 21) of Gilgamos (Gilgamesh), the grandson of Sokkaros. Sokkaros, who, according to Berossus, was the first king to reign in Babylonia after the deluge, was warned by means of divination that his daughter should bear a son who would deprive him of his throne.
Thinking to frustrate the designs of fate he shut her up in a tower, where she was closely watched. But in time she bore a son, and her attendants, knowing how wroth the King would be to learn of the event, flung the child from the tower.
But before he reached the ground an eagle seized him up and bore him off to a certain garden, where he was duly found and cared for by a peasant. And when he grew to manhood he became King of the Babylonians, having, presumably, usurped the throne of his grandfather.
Here we have a myth obviously of solar significance, conforming in every particular to a definite type of sun-legend. It cannot have been by chance that it became attached to the person of Gilgamesh.
Everything in the epic, too, is consonant with the belief that Gilgamesh is a sun-god—his connexion with Shamash (who may have been his father in the tradition given by Ælian, as well as the eagle which saved him from death), the fact that no mention is made of his father in the poem, though his mother is brought in more than once, and the assumption throughout the epic that he is more than human.
Given the key to his mythical character it is not hard to perceive in his adventures the daily (or annual) course of the sun, rising to its full strength at noonday (or mid-summer), and sinking at length to the western horizon, to return in due time to the abode of men.
Like all solar deities—like the sun itself—his birth and origin are wrapped in mystery. He is, indeed, one of the ‘fatal children,’ like Sargon, Perseus, or Arthur. When he first appears in the narrative he is already a full-grown hero, the ruler and (it would seem) oppressor of Erech.
His mother, Rimat-belit, is a priestess in the temple of Ishtar, and through her he is descended from Ut-Napishtim, a native of Shurippak, and the hero of the Babylonian flood-legend. Early in the narrative he is brought into contact with the wild man Eabani, originally designed for his destruction by the gods, but with whom he eventually concludes a firm friendship.
The pair proceed to do battle with the monster Khumbaba, whom they overcome, as they do also the sacred bull sent against them by Anu. Up to the end of the Vlth tablet their conquering and triumphant career is without interruption; Gilgamesh increases in strength as does the sun approaching the zenith.
At the Vllth tablet, however, his good fortune begins to wane. Eabani dies, slain doubtless by the wrath of Ishtar, whose love Gilgamesh has rejected with scorn; and the hero, mourning the death of his friend, and smitten with fear that he himself will perish in like manner, decides to go in search of his ancestor, Ut-Napishtim (who, as sole survivor of the deluge, has received from the gods deification and immortality), and learn of him the secret of eternal life.
His further adventures have not the triumphal character of his earlier exploits. Sunwise he journeys to the Mountain of the Sunset, encounters the scorpion-men, and crosses the Waters of Death. Ut-Napishtim teaches him the lesson that all men must die (he himself being an exception in exceptional circumstances), and though he afterwards gives Gilgamesh an opportunity of eating the plant of life, the opportunity is lost.
However, Ut-Napishtim cures Gilgamesh of a disease which he has contracted, apparently while crossing the Waters of Death, and he is finally restored to Erech.
In these happenings we see the gradual sinking of the sun into the underworld by way of the Mountain of the Sunset. It is impossible for the sun to attain immortality, to remain for ever in the land of the living; he must traverse the Waters of Death and sojourn in the underworld.
Yet the return of Gilgamesh to Erech signifies the fresh dawning of the day. It is the eternal struggle of day and night, summer and winter; darkness may conquer light, but light will emerge again victorious. The contest is unending.
Some authorities have seen in the division of the epic into twelve tablets a connexion with the months of the year or the signs of the zodiac. Such a connexion probably exists, but when we consider that the artificial division of the epic into tablets scarcely tallies with the natural divisions of the poem, it seems likely that the astrological significance of the former was given to the epic by the scribes of Nineveh, who were evidently at some pains to compress the matter into twelve tablets.
Of the astro-theological significance of the narrative itself (one of its most important aspects), we shall perhaps be better able to judge when we have considered it in detail.”
