Rock reliefs form a large part of the extant artistic remains of the Anatolian Hittite Empire (c. 14th century BC).
[1] At Yazılıkaya, just outside the capital of Hattusa, a series of reliefs of Hittite gods in procession decorate open-air "chambers" made by adding barriers among the natural rock formations.
Herodotus, in the Histories (written c. 430 BC), describes the Karabel relief, which he attributes to the legendary Egyptian pharaoh Sesostris:
Also, there are in Ionia two figures of this man [i.e., Sesostris] carved in rock, one on the road from Ephesus to Phocaea, and the other on that from Sardis to Smyrna.
In both places, the figure is over twenty feet high, with a spear in his right hand and a bow in his left, and the rest of his equipment proportional; for it is both Egyptian and Ethiopian; and right across the breast from one shoulder to the other a text is cut in the Egyptian sacred characters, saying: “I myself won this land with the strength of my shoulders.” There is nothing here to show who he is and whence he comes, but it is shown elsewhere.
