Dance of Stars are three of the Kepler – Poinsot polyhedra, the Small Stellated Dodecahedron (5/2, 5), Great Dodecahedron (5, 5/2), and Great Stellated Dodecahedron (5/2, 3), which have been ornamented by the sâzeh tiles, that are used in a large number of Persian tiling that conform local fivefold and tenfold symmetries. In an article that appeared in Science 315, 1106 (2007), the authors proposed the possibility of the use of a set of tiles, girih tiles, by the medieval craftsmen, for the composition of the underlying pattern. Ink outlines for these tiles appear in panel 28 of the Topkapi scroll. I used girih tiles and included rectilinear patterns that appear as small-brick pattern in the Gunbad-i Kabud tomb tower in Maragha, Iran.
