Introduction: Mohsen Foroughi was one of the first-generation Iranian modernist architects who joined Iranian architecture in the 1940s. His knowledge of architecture obtained in one of the most important French architectural schools—École des Beaux-Arts—allowed him to create valuable works by combining the spirit of Iranian architecture with modern values. His interest in education led to the establishment of the foundations of architecture teaching in Iran, based on the lessons taught in Europe. Purpose of the study: The article addresses the works of Mohsen Foroughi, combining modern architecture with the vernacular Iranian architecture. His most significant works include the building of the Senate, the Department of Law at the University of Tehran, the National Bank of Tehran’s Bazaar, and the Saadi Tomb in Shiraz. The article looks at the development of intellectual flows of the time that evolved into social relationships. Methods: In the course of the study, we use descriptive analysis and analysis of library resources. Results: The main characteristics of Foroughi’s work are balance, symmetry, and application of the main elements of traditional Iranian architecture. By better understanding of his works, architects can be more successful in creating today’s architectural projects.

From the viewpoint of preserving the values of sustainable architecture, daylight in the interiors of mosques in hot and dry climates has always faced limitations. The need to use daylight to provide the required lighting and, in contrast, to prevent the scorching desert sun from entering the spaces led to innovative techniques in Iranian architecture. These techniques have gradually evolved along with the development of semantic concepts of space in different periods of Islamic architecture, which has resulted in slight differences in their application in mosque buildings. In this article, while analysing the place of light in mosque architecture, the standard techniques in lighting mosques located in Iran’s hot and dry climate are studied. The employed research method is a combination of qualitative and quantitative approaches. As the current historic-architectural research cannot be based solely on perception-based definitions, authors had to convert the conceptual features into a measurable index. To achieve this, a numerical index with the scale from 0 to 3 has been defined. The scoring was based on documents such as plans, images, etc. Although most case study objects were built over the centuries, they have general characteristics that distinguish them from a specific historical era. The authors studied the application of these techniques in some examples of selected mosques from four periods of Islamic architecture and present the results in the form of trend charts. Furthermore, they observed the principle of continuity in Iranian architecture from the historical period from the beginning of the Islamic period to the Qajar period, and, in accordance with the theoretical foundations of research, analysed the reasons for the ups and downs of each of the techniques.

As one of the earliest human innovations in the architecture of shells, the dome has undergone many changes. This article examines the theory of the Florence Cathedral's(Santa Maria del Fiore) inspiration from the Soltaniyeh Dome of Zanjan. The methodology employed in this research is comparative-descriptive using reliable historical and library sources. A comparative-historical study of 13 domes in Iran(Iranian plateau) and 13 domes in Italy(Eastern Rome Empire) over 2,000 years has examined the evolution of Iranian and Italian domes in terms of construction time and shape. In the next step, the sources that architectural experts have discussed the influence of the dome of Soltaniyeh in Zanjan on the dome of Santa Maria del Fiore have been reviewed. The influence of the golden age of Islam and the achievements of Muslim scholars on the European renaissance in mathematics and geometry has also been explored. The structural similarities, proportions and forms of these two domes show impressive results. It seems that according to historical sources and comparative studies conducted in this study, the dome of Soltaniyeh has a direct impact on the construction of the dome of Santa Maria del Fiore, and the theory first proposed by Professor Sanpaolesi (1972) is conclusive.
