Girih

Girih is the term used in Islamic art for geometric patterns based on stars and polygons. The word, derived from Persian and meaning “knot,” refers to intricate interlacing lines forming a complex weave. These patterns are commonly found on architectural surfaces, in ceramic and stone craftsmanship, wood carvings, and manuscript illuminations.

Girih emerged very early in Islamic art and became especially widespread during the Seljuk, Ilkhanid, Timurid, and Ottoman periods in architecture, decorative arts, and manuscripts. Girih patterns dating back to the 10th and 11th centuries became more distinct during the Seljuk era and reached their most sophisticated forms in Timurid and Ottoman architecture. In Ottoman architecture, girih motifs are frequently seen in the decoration of doors, windows, and mihrabs of tombs, mosques, and madrasas. The visual impact of girih was also employed as a metaphor in classical Turkish poetry, reflecting the intertwined and intricate nature of artistic composition.

Girih patterns are primarily composed of stars, polygons, and interlacing lines. The points where the knots meet create an impression of infinite continuity. These designs are based on symmetry and repetition, establishing both visual and symbolic unity. Initially, girih patterns were drawn directly with ruler and compass in a “weave” form. However, beginning in the 1200s, a significant transformation occurred: artisans began constructing patterns based on five fundamental polygons: pentagon, decagon, hexagon, rhombus, and bowtie.

Girih patterns were not limited to periodic repetition. Starting in the 15th century, they employed self-similarity and scaling techniques to produce nearly perfect quasi-crystalline arrangements. The pattern on the Darb-i Imam Mausoleum dated 1453, for instance, exhibits striking similarities to modern mathematical “Penrose tilings,” demonstrating that this structure had been applied in the Islamic world five centuries before its discovery in the West.

Examples of girih can be found in Seljuk tombs, Timurid and Ilkhanid structures, and early Ottoman mosques and madrasas. It also remained an important decorative style in Safavid and Mughal art.

• Architectural decoration: Girih patterns were used in stone carving, ceramic tilework, stucco, and wood inlay.
• Manuscript works: Girih motifs appeared in manuscript illuminations and the borders of miniatures.
• As literary metaphor: In classical Turkish poetry, it was used as a concept representing delicacy and complexity.

Girih patterns are not merely decorative; they also carry cosmological and metaphysical meanings. The sense of infinite repetition is associated in Islamic aesthetics with the oneness of God and the order of the universe. In a culture where figurative art was limited, geometric abstraction became a powerful visual identity.

In literature, the term girih is derived from its primary meaning of “knot.” Since the word fundamentally means “knot,” it was used in classical poetry to describe the tangles and intricacies of a beloved’s hair. It also served as a metaphor for complex, unresolved emotions within the human heart and for problems that could not be untangled. Girih was sometimes employed to express the unresolved, knotted nature of riddles or difficult dilemmas. In early Turkish literature, the term was commonly used not only in the sense of “knot” but also in relation to magic and archery. In some instances, it was also used to denote geometric patterns.
