Architecture, Building and Structure Design Safavieh History Museum by Babak Ahangar Azizi Islamic and Persian artists developed geometric patterns to a degree of complexity and sophistication previously unknown. These patterns exemplify the Islamic and Persian interest in repetition, symmetry and continuous generation of patterns. The superb assurance of the Islamic designers is demonstrated by their masterful integration of geometry with such optical effects as the balancing of positive and negative areas, interlacing with fluid overlapping and under passing strap work, and a skillful use of color and tone values.
