DENISE-MARIE TEECE: Hello, my name is Denise-Marie Teece… I'm here today with my colleague, Denise Beyazit. Can I ask you: why are all of these tiles together in this case?

DENIZ BEYAZIT: They're all of the same period. They're from the Timurid period. They come from Central Asia, 15th Century. They all come from a building, so from different buildings. And each one… has been created in a different technique. For example, the one which looks like it's a star…in the shape of a twelve-pointed star…this technique is called cuerda seca which is actually a technique where… you draw a line…which helps to separate the colors so they don't fusion together. And they liked to have the walls, all the visible surfaces; they were covered and decorated by these tiles. So that's another particularity of Timurid architecture. They built huge buildings; it was really a monumental style. And so like these three tiles we have here in the case; you have to imagine… let's say, the one which has this strange, curve, which looks like a part of a small circular, shape.

DENISE-MARIE TEECE: It also looks like a puzzle piece.

DENIZ BEYAZIT: Exactly. That is entirely covered by turquoise color. That probably comes from a dome… from an entrance gate. And you have to imagine like… hundreds of them. And they form a kind of honeycomb covering above the entrance.
