Both at Euyuk and Yasili Kaya reliefs in one and the same series are widely separated in artistic conception and execution, some showing the utmost naiveté, others expressing both outline and motion with fair success.
Sultan Berkat built a mosque and enforced Mahommedan law, and with the assistance of the Chinese built the stone wall, which is still in existence between the islands of Kaya Orang and Chermin, by sinking forty junks filled with rock across the mouth of the Brunei river.
Near the site are the rock reliefs of Yasili Kaya in two hypaethral galleries, showing, in the one, two processions composed of over sixty figures meeting at the head of the gallery; in the other, isolated groups of figures, fifteen in number (see for detailed description Murray's Guide to Asia Minor, 18 95, pp. 23 ff.).
