I have termed this second period that of indirect
influence, because the arts did not then penetrate directly into Asia Minor from Assyria, but were conveyed thither through the Persians. The Assyrian Empire had already existed for centuries, and had exercised the supreme power over Asia, before it was disputed by the kingdoms of Persia and Media, united under one monarch. The Persians were probably a rude people, possessing neither a literature nor arts of their own, but deriving what they had from their civilised neighbours. We have no earlier specimen of Persian writing than the inscription containing the name of Cyrus, on the ruins supposed to be those of his tomb, at Murghaub [Pasargarda]; nor any earlier remains of Persian art than the buildings and sculptures of Persepolis, and other monuments to be attributed beyond a question to the kings of the Achæmenian dynasty. It has already been shown that the writing of the Persians was imitated from the Assyrians, and it can as easily be proved that their sculptures were derived from the same source. The monuments of Persepolis establish this beyond a doubt. They exhibit precisely the same mode of treatment, the same forms, the same peculiarities in the arrangement of the bas-reliefs against the walls, the same entrances formed by gigantic winged animals with human heads, and, finally, the same religious emblems. Had this identity been displayed in one instance alone, we might have attributed it to chance, or to mere casual intercourse; but when it pervades the whole system, we can scarcely doubt that one was a close copy, an imitation, of the other. That the peculiar characteristics of the Persepolitan sculptures were derived from the monuments of the second Assyrian dynasty—that is, from those of the latest Assyrian period—can be proved by the similarity of shape in the ornaments and in the costume of many of the figures. Thus, the head-dress of the winged monsters forming the portals is lofty, squared, and richly ornamented at the top, resembling those of Khorsabad and Kuyunjik, and differing from the round, unornamented cap of the older figures at Nimrud.The processions of warriors, captives, and tribute-bearers at Persepolis are in every respect similar to those on the walls of Nimrud and Khorsabad; we have the same mode of treatment in the figures, the same way of portraying the eyes and hair. The Persian artist introduced folds into the draperies; but, with this exception, he certainly did not improve upon his Assyrian model. On the contrary, his work is greatly inferior to it in the general arrangement of the groups and in the elegance of the details.
From whence the Persians obtained the column and other architectural ornaments used at Persepolis, it may be more difficult to determine. We have seen that the column was not unknown to the later Assyrians, although it does not appear to have been employed in the construction of their palaces. The Persians, therefore, may have partly derived their knowledge from them; and partly, perhaps principally, from the Egyptians, whom, before the foundation of Persepolis, they had already conquered. It will be observed that the capitals of their columns frequently assume the shape of Assyrian religious types, the bull for instance; whilst other portions of them nearly resemble in the form of their ornaments, though not in their proportions, those of Egypt.
The Persians introduced into Asia Minor the arts and religion which they received from the Assyrians. Thus the Harpy Tomb and the monument usually attributed to Harpagus at Xanthus, and other still earlier remains, show all the peculiarities of the sculpture of Persepolis, and at the same time that gradual progress in the mode of treatment—the introduction of action and sentiment, and a knowledge of anatomy—which marks the distinction between Asiatic and Greek art. Whilst there was a manifest improvement in the disposition of the draperies and in the delineation of the human form, we still remark, even in the latest works of the Persian period in Asia Minor, the absence of all attempt to impart sentiment to the features, or even to give more than the side view of the human face.
