Nigde Ak Medresse
The mosque Ak Medresse is situated in Nigde.
My reconstruction may have been done according to the rules, namely "back on front", the result looks weird and does not match the photo.
The first layer is much too wide.
Moreover, the photo shows five layers and the reconstruction only four layers.
After implementing the additional rule "back on curve", the missing layer becomes visible.
Instead of the blue "intermediate units" there will be muqarnas units with a wall.
The result is a slimmer and higher muqarnas that matches both Uluengin's analysis and the photo.
Below, the five-layer reconstruction is shown which is based on the rule "back on curve".
Check the animation to find out the composition of this muqarnas.
