Kukeldash madrassa (2) - gp
The north iwan along the inner court has got a spandrel with a geometric pattern. Apart of a text on top this is the only decoration.
As the spandrel of the main entrance, the patterns is generated by decagons, but it looks completely different.
Although it looks more comples, the construction is simplier: it's jus a tiling of decagons and ties.
The complex look is due to the elaboration of the lines as a braid and the colouring of the forms in the pattern filled with multicolour floral motives.
