We can see, however, that there was a civilized race in Babylonia before the Median Conquest, the progress of which must have received a rude shock when the country was overrun by the uncivilized Eastern borderers.
Among the fragmentary notices of this semi-mythical period is the portion of the inscription describing the building of the Tower of Babel and the dispersion.
It is probable from the fragments of Berosus that the incursions and dominion of the Median Elamites lasted about two hundred years, during which the country suffered greatly from them.
The legends of Izdubar or Nimrod commence with a description of the evils brought upon Babylonia by foreign invasion, the conquest and sacking of the city of Erech being one of the incidents in the story. Izdubar, a famous hunter, who claimed descent from a long line of kings, reaching up to the time of the Flood, now comes forward; he has a dream, and after much trouble a half-human creature named Hea-bani is persuaded by Zaidu, the hunter, and two females, to come to Erech and interpret the dream of Izdubar. Hea-bani, having heard the fame of Izdubar, brings to Erech a midannu or tiger to test his strength, and Izdubar slays it. After these things, Izdubar and Hea-bani become friends, and, having invoked the gods, they start to attack the tyrant Khumbaba. Khumbaba dwelt in a thick forest, surrounded by a wall, and here he was visited by the two friends, who slew him and carried off his spoils.
Izdubar was now proclaimed king, and extended his authority over the Babylonian world, his court and palace being at Erech. The goddess Istar, daughter of Anu according to one myth, of Bel according to another, of Sin, the moon god, according to a third, who had loved the shepherd Tammuz, the Sun-god, fell in love with Izdubar. He refused her offers, and the goddess, angry at his answer, ascended to heaven and petitioned her father Anu to create a bull for her, to be an instrument of her vengeance. Anu complied, and created the bull, on which Izdubar and Hea-bani collected a band of warriors and went against it. Hea-bani took hold of the animal by its head and tail, while Izdubar slew it.
Istar on this cursed Izdubar, and descended to Hades to attempt once more to summon unearthly powers against the hero. She descends to the infernal regions, which are vividly described, and, passing through their seven gates, is ushered into the presence of the queen of the dead. The world of love goes wrong in the absence of Istar, and on the petition of the gods she is once more brought to the earth, ultimately Anatu, her mother, satisfying her vengeance by striking Izdubar with a loathsome disease.
