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.

Every year, a large number of the Earth inhabitants have to leave their homeland due to violence and discrimination so that there are now over 60 million displaced people worldwide. Almost 20 million of them are refugees. In this circumstance, refugee camps, considered a common settling way, not only have a great effect on the current lives of refugees, but also influence their future lives because of the long-term presence of refugees in such an environment. The purpose of this study is to review the refugee camps from economic, social, physical, managerial, and environmental perspectives. In the next step, the rational basis of refugee camps as a city is explained by examining city, its features, and its dimensions and comparison with refugee camps. Afterward, diverse criteria are developed to improve the quality of life in various social, environmental and physical dimensions using the livability approach. These criteria are the basis of redesigning Saveh Camp, Iran as a livable city. Finally, a livable city-based design is proposed for the case study.
