Star Patterns – Geometric Splendor. The star motif is one of the most common geometric patterns in Islamic ornamentation. It appears in countless variations, from five to sixteen points, in a variety of materials, scales and applications. Stars are engraved in stonework, decorative ironwork, ceramics, stained glass tracery windows, as well as in marble floors and wooden screens. Particular attention is paid to principles of repetition and continuous permutation. Some of the star patterns have symbolic significance, such as the eight-point star design which is inspired by the octagonal ground-plan of the Dome of the Rock. The octagon is a transitional shape between the circle and square – thus representing heaven (the circle) and earth (square).
