This 1842-1843 calotype by Joseph-Philibert Girault de Prangey depicts the minaret of the Mosque of Sultan al-Hakim in Cairo, Egypt. The unique image is a combination of two negatives, capturing the minaret both from the ground and from an elevated perspective, highlighting the intricate architectural details of the 11th-century structure. This innovative technique, known as a "composite" or "double-exposure", was a hallmark of Prangey's photographic practice and offered a unique perspective on the world, showcasing the artistic potential of this emerging medium.
