Babylonia is a treeless country, and timber had to be imported from the earliest times. The date palm was probably introduced by man, as were certainly the vine and the fig tree, which were widely cultivated, especially in the north. Stone, suitable for building, was very scarce, and limestone, alabaster, marble, and basalt had to be taken from northern Mesopotamia, where the mountains also yield copper and lead and iron. Except Eridu, where ancient workers quarried sandstone from its sea-shaped ridge, all the cities were built of brick, an excellent clay being found in abundance. When brick walls were cemented with bitumen they were given great stability. This resinous substance is found in the north and south. It bubbles up through crevices of rocks on river banks and forms small ponds. Two famous springs at modern Hit, on the Euphrates, have been drawn upon from time immemorial. "From one", writes a traveller, "flows hot water black with bitumen, while the other discharges intermittently bitumen, or, after a rainstorm, bitumen and cold water.... Where rocks crop out in the plain above Hit, they are full of seams of bitumen."[30] Present-day Arabs call it "kiyara", and export it for coating boats and roofs; they also use it as an antiseptic, and apply it to cure the skin diseases from which camels suffer.
Sumeria had many surplus products, including corn and figs, pottery, fine wool and woven garments, to offer in exchange for what it most required from other countries. It must, therefore, have had a brisk and flourishing foreign trade at an exceedingly remote period. No doubt numerous alien merchants were attracted to its cities, and it may be that they induced or encouraged Semitic and other raiders to overthrow governments and form military aristocracies, so that they themselves might obtain necessary concessions and achieve a degree of political ascendancy. It does not follow, however, that the peasant class was greatly affected by periodic revolutions of this kind, which brought little more to them than a change of rulers. The needs of the country necessitated the continuance of agricultural methods and the rigid observance of existing land laws; indeed, these constituted the basis of Sumerian prosperity. Conquerors have ever sought reward not merely in spoil, but also the services of the conquered. In northern Babylonia the invaders apparently found it necessary to conciliate and secure the continued allegiance of the tillers of the soil. Law and religion being closely associated, they had to adapt their gods to suit the requirements of existing social and political organizations. A deity of pastoral nomads had to receive attributes which would give him an agricultural significance; one of rural character had to be changed to respond to the various calls of city life. Besides, local gods could not be ignored on account of their popularity. As a result, imported beliefs and religious customs must have been fused and absorbed according to their bearing on modes of life in various localities. It is probable that the complex character of certain deities was due to the process of adjustment to which they were subjected in new environments.
The petty kingdoms of Sumeria appear to have been tribal in origin. Each city was presided over by a deity who was the nominal owner of the surrounding arable land, farms were rented or purchased from the priesthood, and pasture was held in common. As in Egypt, where we find, for instance, the artisan god Ptah supreme at Memphis, the sun god Ra at Heliopolis, and the cat goddess Bast at Bubastis, the various local Sumerian and Akkadian deities had distinctive characteristics, and similarly showed a tendency to absorb the attributes of their rivals. The chief deity of a state was the central figure in a pantheon, which had its political aspect and influenced the growth of local theology. Cities, however, did not, as a rule, bear the names of deities, which suggests that several were founded when Sumerian religion was in its early animistic stages, and gods and goddesses were not sharply defined from the various spirit groups.
A distinctive and characteristic Sumerian god was Ea, who was supreme at the ancient sea-deserted port of Eridu. He is identified with the Oannes of Berosus,[31] who referred to the deity as "a creature endowed with reason, with a body like that of a fish, with feet below like those of a man, with a fish's tail". This description recalls the familiar figures of Egyptian gods and priests attired in the skins of the sacred animals from whom their powers were derived, and the fairy lore about swan maids and men, and the seals and other animals who could divest themselves of their "skin coverings" and appear in human shape. Originally Ea may have been a sacred fish. The Indian creative gods Brahma and Vishnu had fish forms. In Sanskrit literature Manu, the eponymous "first man", is instructed by the fish to build a ship in which to save himself when the world would be purged by the rising waters. Ea befriended in similar manner the Babylonian Noah, called Pir-napishtim, advising him to build a vessel so as to be prepared for the approaching Deluge. Indeed the Indian legend appears to throw light on the original Sumerian conception of Ea. It relates that when the fish was small and in danger of being swallowed by other fish in a stream it appealed to Manu for protection. The sage at once lifted up the fish and placed it in a jar of water. It gradually increased in bulk, and he transferred it next to a tank and then to the river Ganges. In time the fish complained to Manu that the river was too small for it, so he carried it to the sea. For these services the god in fish form instructed Manu regarding the approaching flood, and afterwards piloted his ship through the weltering waters until it rested on a mountain top.[32]
If this Indian myth is of Babylonian origin, as appears probable, it may be that the spirit of the river Euphrates, "the soul of the land", was identified with a migrating fish. The growth of the fish suggests the growth of the river rising in flood. In Celtic folk tales high tides and valley floods are accounted for by the presence of a "great beast" in sea, loch, or river. In a class of legends, "specially connected with the worship of Atargatis", wrote Professor Robertson Smith, "the divine life of the waters resides in the sacred fish that inhabit them. Atargatis and her son, according to a legend common to Hierapolis and Ascalon, plunged into the waters--in the first case the Euphrates, in the second the sacred pool at the temple near the town--and were changed into fishes". The idea is that "where a god dies, that is, ceases to exist in human form, his life passes into the waters where he is buried; and this again is merely a theory to bring the divine water or the divine fish into harmony with anthropomorphic ideas. The same thing was sometimes effected in another way by saying that the anthropomorphic deity was born from the water, as Aphrodite sprang from sea foam, or as Atargatis, in another form of the Euphrates legend, ... was born of an egg which the sacred fishes found in the Euphrates and pushed ashore."[33]
As "Shar Apsi", Ea was the "King of the Watery Deep". The reference, however, according to Jastrow, "is not to the salt ocean, but the sweet waters flowing under the earth which feed the streams, and through streams and canals irrigate the fields".[34] As Babylonia was fertilized by its rivers, Ea, the fish god, was a fertilizing deity. In Egypt the "Mother of Mendes" is depicted carrying a fish upon her head; she links with Isis and Hathor; her husband is Ba-neb-Tettu, a form of Ptah, Osiris, and Ra, and as a god of fertility he is symbolized by the ram. Another Egyptian fish deity was the god Rem, whose name signifies "to weep"; he wept fertilizing tears, and corn was sown and reaped amidst lamentations. He may be identical with Remi, who was a phase of Sebek, the crocodile god, a developed attribute of Nu, the vague primitive Egyptian deity who symbolized the primordial deep. The connection between a fish god and a corn god is not necessarily remote when we consider that in Babylonia and Egypt the harvest was the gift of the rivers.
The Euphrates, indeed, was hailed as a creator of all that grew on its banks.
O thou River who didst create all things,
When the great gods dug thee out,
They set prosperity upon thy banks,
Within thee Ea, the King of the Deep, created his dwelling...
Thou judgest the cause of mankind!
O River, thou art mighty! O River, thou art supreme!
O River, thou art righteous![35]
