The Metropolitan Museum of Art, and private collections related to a mystical branch of Islam known as Sufism. While differing Muslim sects and diverse nationalities of the Islamic world may not always share a single religious or cultural ideology, the mystical and romantic aspects of Sufism tend to appeal to a global audience. Inspired by Sufi ideologies and the poetry of celebrated mystics such as al-Ghazzali (d. 1111) and Jalal al-Din Rumi (d. 1273), artists from the medieval Islamic period through the present day have produced works of art ranging from ceramic and metal wares to illustrated manuscripts and photographs.
