We studied these ornaments regionally to identify regional variations and classified them based on tastes of patrons. Meanwhile, we analysed the formal aspects of these ornaments, including their dimension, proportion, dominant colour, material, and techniques. In addition, the study conducted detailed observations of their characteristics, such as margins, apex, thickness of stem scrolls and vents, to define their constructive elements, aesthetical properties, and design principles that reveal date, region, and styles. This research not only provides a comprehensive guide to the evolution of Islamic abstract vegetal ornaments for architectural conservation projects but also serves as a reference for the comparative and critical analysis of contemporary Islamic-inspired ornaments.

To this end, a detailed survey is conducted on the decorative patterns of 100 surviving buildings in the Muslim architectural world. The patterns are analyzed and chronologically organized to determine the earliest surviving examples of these adorable ornaments. The origins and radical artistic movements throughout the history of IGPs are identified. With consideration for regional impact, this study depicts the evolution of IGPs, from the early stages to the late 18th century.

The great role of geometry in Islamic architecture due to restriction of using natural figures is an example. In this research, the application of Islamic geometrical patterns (IGPs), and suitability of their usage over architectural elements in terms of timescale accuracy and architectural-style matching is studied. A detailed survey of hundred wellsurviving buildings throughout the Muslim world of architecture has been conducted for this purpose and as a result, not only origin of patterns identified, but also radical artistic movements throughout the history of Islamic geometric ornaments revealed. Finally, this study sketches the evolution of IGPs through history, while regional diversities are also taken into account.
