The ruddy colour which the swollen river derived from the soil at a certain season was ascribed to the blood of the god, who received his death wound in Lebanon at that time of the year, and lay buried beside the sacred source."[55] In Babylonia the river was regarded as the source of the life blood and the seat of the soul. No doubt this theory was based on the fact that the human liver contains about a sixth of the blood in the body, the largest proportion required by any single organ. Jeremiah makes "Mother Jerusalem" exclaim: "My liver is poured upon the earth for the destruction of the daughter of my people", meaning that her life is spent with grief. Inspiration was derived by drinking blood as well as by drinking intoxicating liquors--the mead of the gods. Indian magicians who drink the blood of the goat sacrificed to the goddess Kali, are believed to be temporarily possessed by her spirit, and thus enabled to prophesy.[56] Malayan exorcists still expel demons while they suck the blood from a decapitated fowl.[57] Similar customs were prevalent in Ancient Greece. A woman who drank the blood of a sacrificed lamb or bull uttered prophetic sayings.[58] But while most Babylonians appear to have believed that the life principle was in blood, some were apparently of opinion that it was in breath--the air of life. A man died when he ceased to breathe; his spirit, therefore, it was argued, was identical with the atmosphere--the moving wind--and was accordingly derived from the atmospheric or wind god. When, in the Gilgamesh epic, the hero invokes the dead Ea-bani, the ghost rises up like a "breath of wind". A Babylonian charm runs: The gods which seize on men Came forth from the grave; The evil wind gusts Have come forth from the grave, To demand payment of rites and the pouring out of libations They have come forth from the grave; All that is evil in their hosts, like a whirlwind, Hath come forth from the grave.[59] The Hebrew "nephesh ruach" and "neshamah" (in Arabic "ruh" and "nefs") pass from meaning "breath" to "spirit".[60] In Egypt the god Khnumu was "Kneph" in his character as an atmospheric deity. The ascendancy of storm and wind gods in some Babylonian cities may have been due to the belief that they were the source of the "air of life". It is possible that this conception was popularized by the Semites. Inspiration was perhaps derived from these deities by burning incense, which, if we follow evidence obtained elsewhere, induced a prophetic trance. The gods were also invoked by incense. In the Flood legend the Babylonian Noah burned incense. "The gods smelled a sweet savour and gathered like flies over the sacrificer." In Egypt devotees who inhaled the breath of the Apis bull were enabled to prophesy.
