Drawing muqarnas within circular and elliptical geometric frameworks does not impose any limitation on the choice of rosette (shamseh) due to the absence of corners in the plan. In such cases, designers can freely select the rosette without concern for alignment with the angles of the geometric framework. However, when the geometric framework contains multiple corners, selecting an appropriate rosette becomes a significant design challenge, as it must respond to the framework and coordinate its radial angles with those of the geometric framework. This coordination may involve the intersection of the rosette’s radial extensions with the corners of the framework, or alternatively, the geometric framework may play a passive role in guiding the choice of the muqarnas rosette. Considering the extensive experience of Asghar Sha’rbaf, a recognized master in muqarnas design, and analyzing his documented works in the book Selected Works, the present study investigates this issue across a collection of his designs. The research specifically addresses the following questions: How do the corner angles of the geometric framework influence the selection and construction of the rosette? In Sha’rbaf’s polygonal-geometric-framework designs, are rosettes drawn with equal radial angles, or do they display deliberate variations to achieve geometric harmony? The main objective is to evaluate how geometric frameworks with plans exceeding four sides affect the form and alignment of rosettes in Sha’rbaf’s muqarnas designs. By examining the relationship between the rosette and the underlying geometric framework, this study not only enhances the understanding of muqarnas plan geometries but also provides practical guidance for selecting and accurately drawing rosettes in complex designs. Data were collected through extensive library research, scanning and documenting muqarnas designs, and analyzing the results using planar geometry and angular relationships. The findings reveal that in Sha’rbaf’s designs with geometric frameworks of more than four sides, rosettes are generally aligned with the geometric framework, meaning their radial angles extend through the corners. In cases where direct alignment is absent, the corners are instead coordinated with the axes of some horizontal elements. Slight variations in radial angles indicate that rosettes are not always perfectly regular, allowing them to adapt and maintain overall geometric harmony with the geometric framework.
