CHALDÆA, BABYLONIA, AND ASSYRIA.
THE traditional culture of the land of the Euphrates and Tigris is not younger than that of the Nile. Though the third dynasty (commencing, according to Berosos, with the twenty-third century B.C.) is the first of which we have monumental remains, it cannot be denied that long before that time an important people had inhabited the country, a nation very different from the nomadic hordes which then, as to-day, roved through the neighboring deserts. Several races of antiquity were conscious that the most primitive people of civilization had lived in the land of the two streams. The Jews considered that to have been their original home. The Patriarch Abraham had emigrated from Chaldæan Ur to Canaan. The Greek legend of Deucalion points to the history of Mesopotamia in the same manner as does the Jewish myth of the Deluge; the oldest Greek knowledge of astronomy, astrology, and the calculation of time seems to have been derived from the same source. The tale of the division of the nations in Babel, and their spreading over the face of the earth from that point, is certainly based upon the existence of a most ancient centre of civilization upon the banks of the Euphrates.
The land offered no materials for monuments which, like those of Egypt, could stand uninjured through thousands of years. The narrow valley of the Nile is enclosed by the cliffs of the desert border, which seemed directly to encourage, by the excellence of the building-stone there procured, the erection of immense and indestructible works. The plain of Mesopotamia, on the other hand, spread far beyond the courses of the two streams, losing itself in deserts without any line of eminences as a demarcation. The remote mountains offered no quarries at all comparable to those of Egypt. The soil was of good clay for the manufacture of bricks, but fuel was lacking with which to burn and harden them. The inhabitants of the land were generally obliged to content themselves with drying the clay in the sun, making up by the great thickness of the masonry for the firmness lacking to the material. They further strengthened the massive walls with a facing, or with buttress-like piers of burnt brick, or solidified the interior with alternate courses of this harder substance. The bitumen which still flows at Hit, on the Euphrates, north of Bagdad at the southern border of the higher alluvial terrace of Assyria, was an excellent substance for cementing the bricks; in more important works it was used alternately with lime-mortar: in common buildings, or in the interior of the thickest walls, clay kneaded with straw answered the purpose of a cement.
It is natural that little should now remain of such structures. They could only survive the thousands of years that have elapsed since their building, when an immense thickness secured at least the kernel of the wall, or when the ruins of other buildings early covered and protected them. The remains of ancient Chaldæa are generally nothing more than formless heaps of rubbish, many of which have not yet been opened. Taylor, Loftus, and their predecessors, Ainsworth, Chesney, and Layard, discovered the ruins of over thirty cities in the lower half of the Mesopotamian plain. Of these, Mugheir (the ancient Ur), Warka (Erech), Niffer (Nipur), and Abou-Sharein offered the most important remains of great age; while the ruins of Sura, Tel Sifr, Calvadha, and Ackercuf are mainly of the later Chaldæan period.
