Anatolian prayer rugs of the 15 and 16 Centuries. These are rugs with a pointed Mihrab and open field except for a distinctive intended or lobed quadrilateral medallion. The main border may be Kufesque. An inner border may have e reentrant octagon or “keyhole” at bottom or both ends. This design is shown in rugs in paintings of northern Italy of the 16 and 17 Centuries. The earliest representation of these prayer rugs is in a painting in the National Gallery, London, by Gentile Bellini made in 1507.
