Contarini also wrote, "The empire of Uzun-Hassan is very extensive, and is bounded by Turkey and Caramania, belonging to the Sultan, and which latter country extends to Aleppo. Uzun-Hassan took the kingdom of Persia from Causa, whom he put to death. The city of Ecbatana, or Tauris, is the usual residence of Uzun-Hassan; Persepolis or Shiras ..., which is twenty-four days journey from thence, being the last city of his empire, bordering on the Zagathais, who are the sons of Buzech, sultan of the Tartars, and with whom he is continually at war. On the other side is the country of Media, which is under subjection to Sivansa, who pays a kind of yearly tribute to Uzun-Hassan. It is said that he has likewise some provinces on the other side of the Euphrates, in the neighbourhood of the Turks. The whole country, all the way to Ispahan... is exceedingly arid, having very few trees and little water, yet it is fertile in grain and other provisions.
