The porch of AllahverdiKhan was built in the Safavid era,in the proximity of the shrine of Imam Reza and by the order of AllahverdiKhan,the military commander of the Safavid era.The construction of a porch contemporary with the life of Ṣadr ad-Dīn Muḥammad Shīrāzī,also called MullāṢadrā,is one of the greatest scientists of the Islamic world and the founder of transcendent wisdom,whom AllahverdiKhan had a special respect for his doctrine.MullaSadra's wisdom has had a great impact on the religious,doctrinal and especially the architectural teachings of his time and beyond. Architecture,due to its influence on culture and beliefs,spreads the worldview of the architects of its time,so it is assumed that porch architecture is able to reveal the basic concepts of formation that are rooted in the wisdom of MullaSadra.In this regard a comparative study of the formation of the porch of AllahverdiKhan,based on the ontology of the transcendent wisdom as the most complete wisdom of the Orient, can be examined in the process of its construction.Therefore,the question raised is:How did MullaSadra's ontological discussions influence the formation of the porch of AllahverdiKhan and how did these influences manifest themselves in the body and meaning of the porch?Therefore,in the present study,we intend to bring the principles of MullaSadra ontology to the forefront in this magnificent building based on scientific findings.The existence of this question and the close relationship between these two famous characters of the Safavid era,along with the creation of this building in the most important religious place of Iran,can strengthen the relationship between transcendent wisdom in the formation of the building.In addition,examining the building and its adaptation with the ontological principles of this wisdom can provide more accurate answers to the questions raised.For this purpose,in this study,with the method of descriptive-analysis and logical reasoning strategy,the four ontological bases of MullaSadra's wisdom in the formation of the porch will be examined.
