The portable mihrab from the Mashhad of Sayyida Ruqayya dates to the Fatimid period and is crafted entirely from wood.[1] It is notable both because of its wooden construction and because it is not built into a larger permanent structure but is freestanding and can be moved. It was commissioned by al-Sayyida 'Ulam al-Amiriyya, the wife of the Fatimid caliph al-Amir, in the 12th century. The mihrab currently resides in the Museum of Islamic Art in Cairo, Egypt.[1]
The basic structure of the mihrab, which stands 210 centimetres (83 in) tall, 111 centimetres (44 in) wide, and 45 centimetres (18 in) deep,[1] is a rectangular prism with a niche on its front. The perimeter of the façade includes Qur'anic verses.[1] The surface of the mihrab contains foliated and geometric patterns, among vegetal designs.[1]
