Next to their edifices, the most remarkable of the remains which the Chaldaeans have left to after-ages, are their burial-places. While ancient tombs are of very rare occurrence in Assyria and Upper Babylonia, Chaldaea Proper abounds with them. It has been conjectured, with some show of reason, that the Assyrians, in the time of their power, may have made the sacred land of Chai the general depository of their dead, much in the same way as the Persians even now use Kerbela and Nedjif or Meshed Ali as special cemetery cities, to which thousands of corpses are brought annually. At any rate, the quantity of human relics accumulated upon certain Chaldaean sites is enormous, and seems to be quite beyond what the mere population of the surrounding district could furnish. At Warka, for instance, excepting the triangular space between the three principal ruins, the whole remainder of the platform, the whole space within the walls, and an unknown extent of desert beyond them, are everywhere filled with human bones and sepulchres. In places coffins are piled upon coffins, certainly to the depth of 30, probably to the depth of 60 feet; and for miles on every side of the ruins the traveller walks upon a soil teeming with the relics of ancient, and now probably extinct, races. Sometimes these relics manifestly belong to a number of distinct and widely separate eras; but there are places where it is otherwise. However we may account for it--and no account has been yet given which is altogether satisfactory--it seems clear, from the comparative homogeneousness of the remains in some places, that they belong to a single race, and if not to a single period, at any rate to only two, or, at the most, three distinct periods, so that it is no longer very difficult to distinguish the more ancient from the later relics. Such is the character of the remains at Mugheir, which are thought to contain nothing of later date than the close of the Babylonian period, B. C. 538; and such is, still more remarkably, the character of the ruins at Abu-Shahrein and Tel-el-Lahm, which seem to be entirely, or almost entirely, Chaldaean. In the following account of the coffins and mode of burial employed by the early Chaldaeans, examples will be drawn from these places only; since otherwise we should be liable to confound together the productions of very different ages and peoples.
