Double ‘S’ in this word suggest us that this City was constructed by some people that used to live in Anatolia. Nevertheless we haven’t certain information about its construction .First it came into view in the Hellenistic Period. Alexander the Great who had conquered almost all the cities around couldn’t somehow master this one (334 B.C.). The City lived its most brilliant and mighty days in the 2nd and 3rd Centuries A.D. It was deserted in the 5th Century completely for some reasons or other.
