Acemhöyük, which is located within the boundaries of Yeşilova Town, approximately 18 km to the northwest of Aksaray, one of the most important archaeological centers of Anatolia. As a result of excavations carried out here until the present-day, many archaeological findings have been uncovered that shed light on ancient Anatolian history. Two more documents written in Old Assyrian were acquired for the Acemhöyük cuneiform written record archives in the excavation activities realized in 2012 and 2013. The first of these two documents was a label found in 2012. The other was a tablet, which was awaited for a long time from Acemhöyük and found in 2013. These two documents once again show that Acemhöyük, one of the main cities of Anatolia in the last periods of the Old Assyrian Period, preserved its importance when the economic relations between Anatolia and Northern Mesopotamia decreased. Furthermore, this ancient settlement place displays once again what an important archaeological center it is for Ancient Anatolian history.

From the west wing of the Sarıkaya palace at Acemhöyük have come objects of a variety of precious materials, including gold, ivory, rock crystal and obsidian. Before the systematic excavations of the site began, much damage had been done in this area by villagers in search of stone or clay. Although the disturbed condition of the palace remains has thus prevented a clear understanding of the provenience of these objects, recent excavations have contributed new information for this inquiry. Investigations at the palace, in particular in Room 17, have established that the ground floor of this two-story structure served for storage purposes. That the second floor was used at least in part to protect valuable possessions is indicated by the provenience of the obsidian plate and the radiolarium plate with stand which form the subject of this discussion. They were recovered from the collapsed ceiling debris in Room 17 of the Sarıkaya palace, at a height of 2.5 m. above the floor level.

During the 1978 excavation campaign at Acemhöyük, sponsored by the Turkish Historical Society, the General Directorate of Antiquites and Museums and Ankara University, the Sarıkaya palace and its vicinity were investigated. Finds of interest and relevance to the subject of this article were recovered from excavations of the palace foundations and contemporar building levels, where the effects of weathering had removed some of the mudbrick walls not taken down during earlier campaigns. Among these finds are bullae with seal impressions, and large fragments of a painted vase, which provide new evidence for aspects of Anatolian art and architecture of the 18th century B.C.
