Muḥammad Ṣādiq

The report of his 1861 visit to Medina was later published in 1877 in the Egyptian Military Gazette and then in a book, Summary of the Exploration of the Wajh-Madinah Hijaz Route and its Military Cadastral Map. His other publications include: • Collection de Vues Photographiques de La Mecque et de Médine, 1881. This was a set of twelve photographs of stations of the Hajj, including four panoramas. • Mash'al al-mahmal ("The Torch of the Mahmal"), 1881. • Kawkab al-hajj fi sayr al-mahmal bahran wa sayrihi barran ("The Star of the Hajj along the Travels of the Mahmal by Sea and Land"), 1886. • Dalil al-hajj li'l-warid nin Makkah wa al-Madinah ("The Guide to the Hajj for Those Arriving in Makkah and Madinah from every Direction"), 1896. All his books combine photographs and written advice for Hajj pilgrims based on his repeated visits to the area. His publications in French were a summary of his work that missed out the detail of his Arabic publications, so for a long time the non-Arabic world was unaware of his achievements.

• Illustration — The Kaaba, photographed in 1880 Sadiq used a wet-plate collodion camera, which had been invented in the 1850s. This produced negatives on wet glass plates, requiring a portable darkroom. From these negatives he made albumen prints which he signed or, later, stamped. The sanctuaries of Mecca and Medina are the holiest sites of Islam. As part of the Hajj which is one of the Five Pillars of Islam, pilgrims perform rituals at Mecca and other nearby sites. On his expeditions from 1861 to 1881, Sadiq photographed the interiors and exteriors of sites on the Hajj pilgrimage route as well as at Medina. Photographing Al-Masjid an-Nabawi (The Prophet's Mosque) and its surroundings in Medina on 11 February 1861, he noted in his diary that no one had taken such photographs before. He used walls and mosque roofs as vantage points to capture panoramas of the cities. He also photographed people connected to the holy sites. As well as the Hajj pilgrims walking around the Kaaba, he photographed Shaykh 'Umar al-Shaibi, the keeper of the key of the Kaaba, and Sharif Shawkat Pasha, guardian of the Prophet's Mosque. In 1876, his photographs of Medina were displayed at the Centennial Exposition in Philadelphia. He presented an album of twelve photographs at the 1881 Third International Conference of Geographers in Venice, winning a gold medal. As a result, this set was published as Collection de Vues Photographiques de La Mecque et de Médine. His photographs are held today by collections including the Khalili Collection of Hajj and the Arts of Pilgrimage, the Victoria and Albert Museum, the Reiss Engelhorn Museum, and the Harvard Fine Arts Library. The curator Claude Sui describes Sadiq's achievements in photography as very significant: "[T]he sheer quality of his photographs is evidence of his talent in this field and reveals professional standards in his handling of the wet collodion procedure". His photography reflects both a cartographer's awareness of spatial relationships and a devout Muslim's connection to the region, culture, and people.
