An Ontological Approach to Islamic Geometric Ornamentation

Why did geometry become the primary visual language of Islamic civilization? For over a century, the answer was framed as a negative: a reaction to a religious ban on figures. This article reclaims the "positive motivation" behind Islamic geometric ornamentation, positioning it as a structural manifestation of metaphysical reality. By integrating historiographic criticism, philosophical analysis, and comparative art history, this study explores: The Ontological Core: How geometry serves as an aesthetic translation of Unity in Multiplicity (Wahdat al-kathra). Mathematical Sophistication: Evidence of quasi-crystalline structures and advanced grids as proof of intentional intellectual investment rather than mere decoration. The Turkish Case Study: Examining the continuity of geometric traditions from pre-Islamic Central Asia to the Ottoman "naturalist" era, demonstrating that geometry remained a structural principle even when motifs evolved. Spatial Metaphysics: The role of Muqarnas and light-geometry interactions in creating an experience of Divine Presence. Ultimately, this paper posits that Islamic geometry is not a void filled by the absence of figures, but a bridge between the mathematical order of the cosmos and human perception.
