All the knowledge which we in reality possess regarding the ancient palatial architecture of the Euphrates valley[77] is derived from the exploration of the palaces erected by the great Assyrian dynasty of Nineveh during the two centuries and a half of its greatest prosperity. Fortunately it is a period regarding the chronology of which there is no doubt, since the discovery of the Assyrian Canon by Sir Henry Rawlinson,[78] extending up to the year 900 B.C.: this, combined with Ptolemy’s Canon, fixes the date of every king’s reign with almost absolute certainty. It is also a period regarding which we feel more real interest than almost any other in the history of Asia. Almost all the kings of that dynasty carried their conquering arms into Syria, and their names are familiar to us as household words, from the record of their wars in the Bible. It is singularly interesting not only to find these records so completely confirmed, but to be able to study the actual works of these very kings, and to analyse their feelings and aspirations from the pictures of their actions and pursuits which they have left on the walls of their palaces. From the accounts left us by the Greeks we are led to suppose that the palaces of Babylon were superior in beauty and magnificence to those of Nineveh; and, judging from the extent and size of the mounds still remaining there, it is quite possible that such may have been the case; but they are so completely ruined, and have been so long used as quarries, that it is impossible to restore, even in imagination, these now formless masses. One thing seems nearly certain, which is, that no stone was used in their construction. If, consequently, their portals were adorned with winged bulls or lions, they must have been in stucco. If their walls were covered with scenes of war or the chase, as those of Nineveh, they must have been painted on plaster; so that, though their dimensions may have been most imposing and their splendour dazzling, they must have wanted the solidity and permanent character so essential to true architectural effect. It is the employment of stone which alone has enabled us to understand the arrangements of the Assyrian palaces. Had not their portals been marked by their colossal genii, we should hardly have known where to look for them; and if the walls of their apartments had not been wainscoted with alabaster slabs, we should never have been able to trace their form with anything like certainty. Practically, all we know of Assyrian art is due to the fact of their having so suitable a material as alabaster close at hand, and to the skill with which they knew how to employ it. Had their walls only been plastered, the mounds of Khorsabad and Nimroud would have remained as mysterious now as they were before Layard and Botta revealed to us their splendours. NINEVEH.
