The date of the epoch in which this writing first began to be used was probably about 4500 B.C. and it persisted until the first century B.C. The Assyrians employed it from about 1500 B.C. until about the beginning of the sixth century B.C. This ancient form of writing was thus used first by the Sumerians, then by their Babylonian and Assyrian conquerors, then by those Persians who finally overthrew the Babylonian and Assyrian empire. The Sacred Literature of Babylonia The literature which this peculiar and individual script has brought down to us is chiefly religious, magical, epical, and legendary. The last three categories are dealt with elsewhere, so that it only falls here to consider the first class, the religious writings. These are usually composed in Semitic Babylonian without any trace of Akkadian influence, and it cannot be said that they display any especial natural eloquence or literary distinction. In an address to the sun-god, which begins nobly enough with a high apostrophe to the golden luminary of day, we find ourselves descending gradually into an atmosphere of almost ludicrous dullness. The person praying desires the sun-god to free him from the commonplace cares of family and domestic annoyances, enumerating spells against all of his relatives in order that they may not place their 'ban' upon him. In another, written in Akkadian, the penitent addresses Gubarra, Merodach, and other gods, desiring that they direct their eyes kindly upon him and that his supplication may reach them. Strangely enough the prayer fervently pleads that its utterance may _do good to the gods!_ that it may let their hearts rest, their livers be quieted, and gladden them like a father and a mother who have begotten children. This is not so strange when we come to consider the nature of these hymns, many of which come perilously near the border-line of pure magic--that is, they closely resemble spells. We find, too, that those which invoke the older deities such as Gibi the fire-god, are more magical in their trend than those addressed to the later gods when a higher sense of religious feeling had probably been evolved. Indeed, it does not seem too much to say that some of these early hymns may have served the purpose of later incantations. Most of those 'magical' hymns appear to have emanated from that extremely ancient seat of religion, Eridu, and are probably relics of the time when as yet magic and religion were scarcely differentiated in the priestly or the popular mind. Hymn to Adar A fine hymn to Adar describes the rumbling of the storm in the abyss, the 'voice' of the god: The terror of the splendour of Anu in the midst of heaven. The gods, it is said, urge Adar on, he descends like the deluge, the champion of the gods swoops down upon the hostile land. Nusku, the messenger of Mul-lil, receives Adar in the temple and addresses words of praise to him:
