Islamic Geometric Pattern vs Pattern and Decoration
イスラム幾何学文様 / パターン・アンド・デコレーション
Both sit in Ornament, so the question is not what they belong to but how they behave. One is technique and the other style. They are reached for with some of the same intent, which is where they get confused.

Divides, repeats and combines circles, squares, polygons and stars, building infinite extension and order on a finite plane.
Pattern and Decoration

A movement that argued head-on with modernism's premise that ornament is inferior. It brought the repetitions of Islamic geometry, quilts, wallpaper and textiles onto large canvases and placed women's handwork and non-Western idioms at the centre of art. The starting point for treating decoration as a political question.
| Islamic Geometric Pattern | Pattern and Decoration | |
|---|---|---|
| Era | 8th century– | 1975–1985 |
| Family | Ornament | Ornament |
| Kind | Technique | Style |
| Cues | Compass construction / Star forms / Repeating units / Interlacing lines | Repeating pattern covering the whole surface / Quotation of quilts and textiles / Reference to non-Western ornament / All-over composition without borders |
| Best used for | Filling walls and ceilings so the surface reads continuous, with no visible seam. · Deriving screens and modular building parts from a single repeating unit. | Surface and packaging systems in textiles, hospitality and cosmetics where the identity is a repeating field rather than a mark · Cultural programmes and publications that need ornament to carry an argument about whose craft counts |
| Type | If lettering enters, give it its own band and leave the grid intact. | Type set inside the pattern at the same visual weight as the motif, so that nothing sits on top of the decoration. |
| Composition | Derive the unit from the construction circle and size the field in whole units. | An edge-to-edge repeat with no frame and no focal point, the format read as a cut from an unbounded field. |
| Material | Pierced stone, assembled wood, inlaid tile, crossings shown as level changes. | Fabric, print or tile whose repeat is honest, the join left visible, with unrelated patterns allowed to meet. |
| Caution | Star shapes pasted together without the construction leave lines that miss at the crossings, and the error multiplies when repeated. The Islamic world is not one culture, so check region, dynasty, material and use. | Quoting the patterns without checking where they came from drops the respect for handwork at its core and leaves a jumble. Framing a modernist white centre with pattern reinstates the hierarchy it overturned. |
