+68+. These pictures of the future world are crude, and usually stand side by side with others; they are experiments in eschatology. But the constructive imagination moved more and more toward an organized underground hades as the sole abode of the dead--the place to which all the dead go. Such a hades is found among the civilized peoples of antiquity, Egyptians, Semites, Hindus, Greeks, and Romans, and, in more recent times, among the Teutons (Scandinavians). The suggestion for this position may have come from the grave (though it does not appear that the grave was regarded as the permanent abode of the dead), and from caverns that seemed to lead down into the bowels of the earth. The descent of souls into a subterranean world offered no difficulties to early imagination: ghosts, like the Australian ancestors, could move freely where living men could not go; where there was no cavern like that by which Æneas passed below,[137] they could pass through the ground. +69+. A lower region offered a wide land for the departed, with the possibility of organization of its denizens. Ghosts gradually lost their importance as a factor in everyday life; sights and sounds that had been referred to wandering souls came to be explained by natural laws. Wider geographical knowledge made it difficult to assign the ghosts a mundane home, and led to their relegation to the sub-mundane region. Further, the establishment of great nations familiarized men with the idea that every large community should have its own domain. The gods were gradually massed, first in the sky, the ocean, and hades, and then in heaven. For the dead the first organization (if that term may be allowed) was in hades; the separation into heaven and hell came later. A specific divine head of the Underworld is found in Egypt, Babylonia and Assyria, India, Greece, Rome, but not in Israel. Such a definite system of government could exist only when something approaching a pantheon had been established; the Babylonians, for example, whose pantheon was vague, had also a vague god of hades. +70+. Theories of the occupations of the dead varied in the early civilized stage, before the rise of the idea of ethical retribution in the other life. In the absence of earthly relations, imagination could conceive of nothing for them to do, and hence an ardent desire for the continuance of earthly life.[138] For the Hebrews the Underworld was without pursuits; the shades sat motionless, in the dress and according to the rank of the upper world, without emotions or aims (except a sparkle of malicious satisfaction when some great man came down from earth), and without religious worship.[139] A similar view was held by the Greeks and the Romans. Certain Egyptian documents speak of mundane occupations for the dead, but these documents belong to a comparatively late stage of culture, and what the earlier view was we do not know.[140] Of Hindu ideas, also, on this point we have only relatively late notices.
