The praises bestowed upon the hieroglyphics of Egypt by Winkleman and others, must be restricted to the mere workmanship; and even then, are exaggerated or misplaced. Considered as works of art, if indeed they can be elevated to that rank, they will be found entirely destitute of accurate discrimination of form, and are more properly conventional representations, dependent upon modes and principles at once limited and arbitrary. These labours, the probable records of primitive history, and of earliest superstition, are of different kinds. The first in use, though not afterwards superseded, were anaglyphics, in which objects are represented by a simple outline, often traced to the depth of several inches. An obvious improvement upon this was to round the angles, and to relieve the figures upon themselves; a mode which very generally obtains. To this manner much ingenuity and forethought has inconsiderately been ascribed, as if adopted against the attacks of time, and to cast a deeper shadow on the symbols. It is, on the contrary, to be judged merely as the resource of an imperfect art. A third, but comparatively rare method, was to elevate the contour, by reducing the surface both within and without. The last and most laborious plan, was to remove the ground entirely, leaving the figures in proper relief. This, the true relievo, was unknown to or unpractised in the ancient arts of Egypt. Even the historical and monumental sculptures just described, partake more of the anaglyphical than of the elevated relievo. Indeed every specimen of this latter is to be assigned to a later period than the first and genuine age. By attending to this, and to the costume of the figures in the most ancient works, data of importance might be discovered, throwing valuable light on the eras of Egypt's mysterious monuments.
The expression, mixed art, selected to discriminate the second epoch, has been adopted, to mark the successive changes in the ancient modes induced by the Persians and the Greeks. The influence exerted upon art by the dominion of the former, amounted merely to a negative,--to the prohibition of its exercise; which, with the destruction of many of its best monuments, produced a deterioration in the few and feeble attempts during the latter years of that dynasty. Mythraism, in which elemental fire was the symbol of the Deity, proscribed the imitative arts in that service, whence, in all other countries, they have sprung. The Persians, says the father of history, have neither temples nor statues. Or, if architecture was encouraged by these conquerors, evidence still remains that their erections were but modifications of materials torn from the mighty structures of past ages. In little more than a century and a half, the Persian was subverted by the Macedonian empire. Yet even in Alexander, the ancient and native arts of Egypt obtained not a patron. The majestic range of temples, palaces, and cities, which bordered the sacred stream of the Nile, furnished so many quarries, of tempting access, whence Alexandria was reared; and the mightiest, as well as most rational trophy of Grecian superiority, received its grandest and most enduring monuments from the stupendous labours of the first age. His successors followed the example; and although, under them, the polished literature of Greece, united with her own subtile philosophy, constituted Alexandria the Athens of the East, yet in sculpture, in architecture, and in religion, to which both were subordinate, the character remained essentially Egyptian, but with certain deviations and additions.
