Zincirli is located in Turkey near the Syrian border and a mountain once called Amanus. It was excavated during years 1888 to 1902 by a German team led by Felix von Luschan and Robert Koldewey. There was found a double walled city and giant statues of lions guardian of the gates of the town. Texts in Akkadian, Phoenician, Aramaic and Luwian allowed to know a few generations of kings of Yadiya and Samal countries.
For example, an inscription of Tiglath-Pileser III, of the 8th century BC, mentions one of them. Panamu, king of Samal, who became one of his subjects.
According to the excavations, which were done again from 2006 to 2009 by the Oriental Institute of the University of Chicago under the direction of David Schloen, the city has been inhabited since the beginning of the Bronze Age. The town was part of Yamhad before being integrated into the Hittites Empire, and becoming an autonomous "Neo-Hittite" stade.
According to the discoverers, Zincirli was the capital of Samal and Yadiya. This toponym was already in use by the Palaeo-Assyrian merchants of Kanes: it appears on some tablets of Kültepe.
The name of Zincirli was Siri'laya, finded with a name of a king : “Ahabbu from Siri'laya”.
My notes of veracity :
Zincirli was the capital of Samal and Yadiya: 4/5
Zincirli was Siri'laya : 3/5
