In one of the building projects 3-400 years ago the sultan wanted a lot of Venetian mirrors. So they bought mirrors and had them shipped . When they arrived they were all broken but the sultan just ordered his workers to make mirror mosaic. And that style became popular so we saw mirror mosaic several places. In one palace they had made sort of a wall decoration and I could not resist making a selfie. Our tour leader who saw this and the picture said: This must be the ultimate selfie!
and here it is.
