This hypothesis would explain two things that need explanation--the absence from Assyria of such tombs as are found in every other country of the Ancient World, and the great size of the Chaldaean cemeteries. Both Loftus and Taylor received the same impression, that the assemblages of coffins, still huge in spite of the numbers that have been destroyed during the last twenty centuries, can never have been due entirely to the second and third rate cities in whose neighbourhood they occur. Piled one upon another they form mounds covering wide spaces of ground, and so high that they may be seen for many miles across the plain.[427] This district must have been the common cemetery of Chaldaea and perhaps of Assyria; the dead of Babylon must have been conveyed there. Is it too much to suppose that by means of rivers and canals those of Nineveh may have been taken there too? Was it not in exactly that fashion that mummies were carried by thousands from one end of the Nile valley to the other, to the places where they had to rejoin there ancestors?[428] But we need not go back to Ancient Egypt to find examples of corpses making long journeys in order to reach some great national burying-place. Loftus received the first hint of his suggestion from what he himself saw at Nedjef and at Kerbela, where he met funeral processions more than once on the roads of Irak-Arabi. From every town in Persia the bodies of Shiite Mussulmans, who desire to repose near the mortal remains of Ali and his son, are transported after death into Mesopotamia.[429] According to Loftus the cemetery of Nedjef alone, that by which the mosque known as _Meched-Ali_ is surrounded, receives the bodies of from five to eight thousand Persians every year. Now the journey between Nineveh and Calah and the plains of Lower Chaldaea was far easier than it is now--considering especially the state of the roads--between Tauris, Ispahan, and Teheran, on the one hand and Nedjef on the other. The transit from Assyria to Chaldaea could be made, like that of the Egyptian mummy, entirely by water, that is to say, very cheaply, very easily, and very rapidly. We are brought up, however, by one objection. Although as a rule subject to the Assyrians, the Chaldaeans were from the eleventh to the seventh century before our era in a constant state of revolt against their northern neighbours; they struggled hard for their independence and waged long and bloody wars with the masters of Nineveh. Can the Assyrian kings have dared to confide their mortal remains to sepulchres in the midst of a people who had shown themselves so hostile to their domination? Must they not have trembled for the security of tombs surrounded by a rebellious and angry populace? And the furious conflicts that we find narrated in the Assyrian inscriptions, must they not often have interrupted the transport of bodies and compelled them to wait without sepulture for months and even years?
