But the history of the dragon's evolution and transmission to other countries is full of complexities; and the dragon-myth is made up of many episodes, some of which were not derived from Babylonia.
In Egypt we do not find the characteristic dragon and dragon-story. Yet all of the ingredients out of which both the monster and the legends are compounded have been preserved in Egypt, and in perhaps a more primitive and less altered form than elsewhere. Hence, if Egypt does not provide dragons for us to dissect, it does supply us with the evidence without which the dragon's evolution would be quite unintelligible.
Egyptian literature affords a clearer insight into the development of the Great Mother, the Water God, and the Warrior Sun God than we can obtain from any other writings of the origin of this fundamental stratum of deities. And in the three legends: The Destruction of Mankind, The Story of the Winged Disk, and The Conflict between Horus and Set, it has preserved the germs of the great Dragon Saga. Babylonian literature has shown us how this raw material was worked up into the definite and familiar story, as well as how the features of a variety of animals were blended to form the composite monster. India and Greece, as well as more distant parts of Africa, Europe, and Asia, and even America have preserved many details that have been lost in the real home of the monster.
In the earliest literature that has come down to us from antiquity a clear account is given of the original attributes of Osiris. "Horus comes, he recognizes his father in thee [Osiris], youthful in thy name of 'Fresh Water'." "Thou art indeed the Nile, great on the fields at the beginning of the seasons; gods and men live by the moisture that is in thee." He is also identified with the inundation of the river. "It is Unis [the dead king identified with Osiris] who inundates the land." He also brings the wind and guides it. It is the breath of life which raises the king from the dead as an Osiris. The wine-press god comes to Osiris bearing wine-juice and the great god becomes "Lord of the overflowing wine": he is also identified with barley and with the beer made from it. Certain trees also are personifications of the god.
But Osiris was regarded not only as the waters upon earth, the rivers and streams, the moisture in the soil and in the bodies of animals and plants, but also as "the waters of life that are in the sky".
"As Osiris was identified with the waters of earth and sky, he may even become the sea and the ocean itself. We find him addressed thus: 'Thou art great, thou art green, in thy name of Great Green (Sea); lo, thou art round as the Great Circle (Okeanos); lo, thou art turned about, thou art round as the circle that encircles the Haunebu (Ægeans)."
This series of interesting extracts from Professor Breasted's "Religion and Thought in Ancient Egypt" (pp. 18-26) gives the earliest Egyptians' own ideas of the attributes of Osiris. The Babylonians regarded Ea in almost precisely the same light and endowed him with identical powers. But there is an important and significant difference between Osiris and Ea. The former was usually represented as a man, that is, as a dead king, whereas Ea was represented as a man wearing a fish-skin, as a fish, or as the composite monster with a fish's body and tail, which was the prototype of the Indian makara and "the father of dragons".
In attempting to understand the creation of the dragon it is important to remember that, although Osiris and Ea were regarded primarily as personifications of the beneficent life-giving powers of water, as the bringers of fertility to the soil and the givers of life and immortality to living creatures, they were also identified with the destructive forces of water, by which men were drowned or their welfare affected in various ways by storms of sea and wind.
Thus Osiris or the fish-god Ea could destroy mankind. In other words the fish-dragon, or the composite monster formed of a fish and an antelope, could represent the destructive forces of wind and water. Thus even the malignant dragon can be the homologue of the usually beneficent gods Osiris and Ea, and their Aryan surrogates Mazdah and Varuna.
By a somewhat analogous process of archaic rationalization the sons respectively of Osiris and Ea, the sun-gods Horus and Marduk, acquired a similarly confused reputation. Although their outstanding achievements were the overcoming of the powers of evil, and, as the givers of light, conquering darkness, their character as warriors made them also powers of destruction. The falcon of Horus thus became also a symbol of chaos, and as the thunder-bird became the most obtrusive feature in the weird anatomy of the composite Mesopotamian dragon and his more modern bird-footed brood, which ranges from Western Europe to the Far East of Asia and America.
