Topkapi scroll
In the Turkish Topkapi palace a scroll is kept with construction desings. Some of them clearly show a girih pattern. In the next picture the five forms are colored.
Dual layer patterns
The drawing on plate 28 of the scroll show a multi-layered pattern.
- The light gray lines match with a pattern of girih tiles. The dark gray lines show the associated line pattern.
- The red lines match with a pattern of much bigger girih tiles.
This drawing shows the girih tiles of both levels:
On other panels of the scroll too we can find 2-layered patterns
