The exceptional collection of architectural and cultural heritage materials at MIT’s Distinctive Collections offers a unique perspective on the artistry and innovation of the Ottoman Middle East. Among its holdings are stucco-stained glass windows, or qamariyyāt and shamsiyyāt, which exemplify the fusion of design, functionality, and cultural exchange in architecture. This case highlights a window from MIT’s Rotch Art Collection, contextualized by exquisite chromolithographs and archival photographs of architectural masterpieces illustrating shared traditions and regional variations in window-making.
