Baha al-Din al-Amili

Baha al-Din al-Amili, also known as Sheikh Bahāʾī, was a prominent Twelver Shia Muslim scholar and polymath born on February eighteenth, fifteen forty-seven, in Jabal Amil, present-day south Lebanon. His family relocated to Iran during his childhood, where his father, Husayn ibn Abd al-Samad, served as the shaykh al-Islam in Herat under Shah Tahmasp I. Sheikh Bahāʾī became a pivotal figure in the intellectual landscape of Safavid Iran, particularly in Isfahan, where he was closely associated with the court of Shah Abbas I.

As a leading architect and planner, Sheikh Bahāʾī played a crucial role in the transformation of Safavid Isfahan. He was the mastermind behind the urban design of Naqsh-e Jahan Square and contributed significantly to the planning of the Shah Mosque, Sheikh Lotfollah Mosque, and Ali Qapu Palace. His innovative designs also influenced the layout of the Imperial Bazaar, and he was involved in hydraulic innovations and water management projects, although some attributions remain speculative.

A prolific author, Sheikh Bahāʾī composed over one hundred treatises in Arabic and Persian, covering a wide range of subjects including jurisprudence, logic, astronomy, mathematics, and theology. His literary contributions also encompassed poetry, where he explored didactic and mystical themes. Notably, in his Persian work Tashrīḥ al-Aflāk, he was among the first Muslim thinkers to suggest the possibility of the Earth's motion, foreshadowing the later spread of Copernican ideas within the Islamic world.

Sheikh Bahāʾī's legacy is marked by his commanding intellectual leadership and cohesive vision, which were instrumental in shaping the scientific, cultural, urban, and intellectual identity of Safavid Iran. With seventy-seven scholars among his students, he stands out as one of the most influential Arab figures in history, leaving an indelible mark on the architectural and scholarly landscape of his time.
