In Babylon, in the sixth century b.c., under the reign of Nebuchadnezzar, the art of tile-painting reached a high state of perfection. The Babylonians had no such splendid alabaster as had the Assyrians, neither had they lime-stone; so they could not make fine sculptured slabs, such as are found at Nineveh and in other Assyrian ruins. But the Babylonians had a fine clay, and they learned how to use it to the best advantage.
