Summary

Description
English: Girih-tile subdivision found in the decagonal girih pattern on a spandrel from the Darb-i Imam shrine, Isfahan, Iran (1453 C.E.). A subdivision rule to construct perfect quasi-crystalline tilings has been identified [1] The thick black lines demarcating girih tiles of decagon and bowtie shapes are subdivided into a smaller pattern, which can also be perfectly generated by a tessellation of girih tiles.
