Alpay Özdural, "Interlocks of Similar or Complementary Figures: Collaboration of Mathematicians and Artisans in the Islamic World," unedited full copy of the original book manuscript submitted to Supplements to Muqarnas in 2003.

A study of Islamic ornamental geometry based on a late medieval Persian manuscript (Bibliothèque nationale de France, Paris, titled Fī tadākhul al-ashkāl al-mutashābiha aw al-mutāwafiqa, Ms. Persan 169). Arguing that mathematics played a major role in Islamic architectural practice and ornamental design, the author interprets the mathematical properties of each geometrical construction in this illustrated primary source, accompanied by his own drawings of their step-by-step construction methods.
