You are absolutely right! I don't know why I thought it was Mt Ararat. I went back and did some research through all of my old pictures and found the name of the mountain (or big hill) that I went to. It is Mt Nemrut, which is close to the city of Ahlat (which which sits on the west side of Lake Van). According to Google Maps, Mt. Nemrut is 247 kilometers east of Diyarbakir. If you go to Google Images and type in Mt Nemrut statues you will see pictures of statues that I saw when I was there. Sorry about the mixup! Oh, also sorry for thinking that they were Greek statues.
