Mardistan
The district of Mardistan, in historic Armenia, corresponds to Artaz, west of the modern Maku, Iranian Azerbaijan. The district of Mardali (Mardaghi) must have been located to the south of Erzerum, north of the Bingöl sources. The Mards of this section of the country were evidently immigrants from the South, says Adontz. The bulk of the tribe occupied one of the southern areas of Vaspurakan (Van), near the upper course of the Centrides River. Xenophon mentioned particularly the extremely fierce and hardy Chalyb tribe, called Chaldaioi by Strabo, living in the Pontic Mountains, and mostly engaged in iron mining and forging. (The Greek marchers covered the distance through this coastal area — 50 parasangs or 150 miles — in seven days.) Several authors classify this people as being of the same stock as the Khaldi-Urarteans. The Taochi and the Phasian tribes, neighbors of the Chalybs, who likewise offered stiff resistance to the Greeks, are represented in the Taiq and Pasian districts of Armenia.
