As the tablet poetically puts it, "he lit up the sky establishing the upper firmament, and caused Anu, Bel, and Ea to inhabit it." He then founded the constellations as stations for the great gods, and instituted the year, setting three constellations for each month, and placing his own star, Nibiru, as the chief light in the firmament. Then he caused the new moon, Nannaru, to shine forth and gave him the rulership of the night, granting him a day of rest in the middle of the month. There is another mutilation at this point, and we gather that the net of Merodach, with which he had snared Tiawath, was placed in the heavens as a constellation along with his bow. The winds also appear to have been bound or tamed and placed in the several points of the compass; but the whole passage is very obscure, and doubtless information of surpassing interest has been lost through the mutilation of the tablet. We shall probably not be far in error if we regard the myth of the combat between Merodach and Tiawath as an explanation of the primal strife between light and darkness. Among the most primitive peoples, the solar hero has at one stage of his career to encounter a grisly dragon or serpent, who threatens his very existence. In many cases this monster guards a treasure which mythologists of a generation ago almost invariably explained as that gold which is spread over the sky at the hour of sunset. The assigning of solar characteristics to all slayers of dragons and their kind was a weakness of the older school of mythology, akin to its deductions based on philological grounds; but such criticism as has been directed against the solar theory--and it has been extensive--has not always been pertinent, and in many cases has been merely futile. In fact the solar theory suffered because of the philological arguments with which it was bound up, and neither critics nor readers appeared to discriminate between these. But we should constantly bear in mind that to attempt to elucidate or explain myths by any one system, or by one hard and fast hypothesis, is futile. On the other hand nearly all systems which have yet attempted to elucidate or disentangle the terms of myth are capable of application to certain types of myth. The dragon story is all but universal: in China it is the monster which temporarily swallows the sun during eclipse; in Egypt it was the great serpent Apep, which battled with Ra and Horus, both solar heroes; in India it is the serpent Vritra, or Ahi, who is vanquished by Indra; in Australia and in some parts of North America a great frog takes the place of the dragon. In the story of Beowulf the last exploit of the hero is the slaying of a terrible fire-breathing dragon which guards a hidden treasure-hoard; and Beowulf receives a mortal wound in the encounter. In the Volsung Saga the covetous Faffnir is turned into a dragon and is slain by Sigurd. These must not be confounded with the monsters which cause drought and pestilence.
