“May we not conclude, then, that originally Merodach also was a solar deity, the particular Sun-god, in fact, whose worship was carried on at Babylon?
The conclusion is verified by the express testimony of the ritual belonging to Merodach’s temple E-Sagila. Here we read that
“In the month Nison, on the second day, two hours after nightfall, the priest must come and take of the waters of the river, must enter into the presence of Bel; and putting on a stole in the presence of Bel, must say this prayer:
“0 Bel, who in his strength has no equal! O Bel, blessed sovereign, lord of the world, seeking after the favour of the great gods, the lord who in his glance has destroyed the strong, lord of kings, light of mankind, establisher of faith!
0 Bel, thy sceptre is Babylon, thy crown is Borsippa, the wide heaven is the dwelling-place of thy liver. …0 lord of the world, light of the spirits of heaven, utterer of blessings, who is there whose mouth murmurs not of thy righteousness, or speaks not of thy glory, and celebrates not thy dominion?
0 lord of the world, who dwellest in the temple of the Sun, reject not the hands that are raised to thee; be merciful to thy city Babylon, to E-Sagila thy temple incline thy face; grant the prayers of thy people the sons of Babylon.”
Nothing can be more explicit than the statement that E-Sagila, the temple of Merodach, was also the temple of the Sun. We thus come to understand the attributes that are ascribed to Merodach and the language that is used of him.
He is “the light of the spirits of heaven,” even as the Son-god, … is “the illuminator of darkness” whose face is beheld by the spirits of the earth. The wide heaven is naturally his dwelling-place, and he raises the dead to life as the sun of spring revivifies the dead vegetation of winter.
The part that he plays in the old mythological poems, in the poems, that is, which embody the ancient myths and legends of Babylonia, is now fully explained. One of the most famous of these was the story of the combat between Merodach and Tiamat, the dragon of darkness and chaos.”
