 The Sagbita mentioned by Assyrian sources was located in the proximity of the cities Kishesim (Kar-Nergal) and Harhar (Kar-Sharrukin).It is now proposed that the absence of any mention of Ecbatana in Assyrian sources can be explained by the possibility that Assyria never became involved as far east as the Alvand mountains, but only in the western Zagros.Sir Henry Rawlinson attempted to prove that there was a second and older Ecbatana in "Media Atropatene" on the site of the modern Takht-i-Suleiman.
