Bahāʾ al‐Dīn Muḥammad ibn Ḥusayn al‐ʿĀmilī (also known as Sheikh Baha'i, Persian: شیخ بهایی) (18 February 1547 – 1 September 1621) was an Arab Iranian Shia Islamic scholar, philosopher, architect, mathematician, astronomer and poet who lived in the late 16th and early 17th centuries in Safavid Iran. He was born in Baalbek, Ottoman Syria (present-day Lebanon) but immigrated in his childhood to Safavid Iran with the rest of his family. He was one of the earliest astronomers in the Islamic world to suggest the possibility of the Earth's movement prior to the spread of the Copernican theory. He is considered one of the main co-founders of Isfahan School of Islamic Philosophy. In later years he became one of the teachers of Mulla Sadra.He wrote over 100 treatises and books in different topics, in Arabic and Persian. A number of architectural and engineering designs are attributed to him, but none can be substantiated with sources. These may have included the Naqsh-e Jahan Square and Charbagh Avenue in Isfahan,. He is buried in Imam Reza's shrine in Mashad in Iran.
