Where was the decree issued that Antoine Galland  was called upon, with two other experts, to make  lithographic copies of in Cairo ?
Antoine Galland (1763–1851) Antoine Galland (17631851) was a publisher and printer during the French Revolution and First Empire. As a printer he joined the Commission des Sciences et des Arts, a body of technical experts ("savants") sent to Egypt in 1798 to aid the work of the French expeditionary force in its successful invasion. He was therefore in Cairo when the newly discovered Rosetta Stone arrived in the city. With two other experts (Jean-Joseph Marcel and Nicolas-Jacques Conté) he was called on to make lithographic copies from the stone. These copies, the first seen in Europe, were used by Silvestre de Sacy and Johan David Åkerblad in their early attempts to decipher the hieroglyphic and demotic scripts.
Mamluk architecture Mamluk architecture was a flowering of Islamic art during the reign of the Mamluk Sultanate (1250–1517), which is most visible in medieval Cairo. Religious zeal made them generous patrons of architecture and art, it was highly influenced by the Ancient Egyptian architecture and Coptic architecture within Egypt. Trade and agriculture flourished under Mamluk rule, and Cairo, their capital, became one of the wealthiest cities in the Near East and the center of artistic and intellectual activity. This made Cairo, in the words of Ibn Khaldun, "the center of the universe and the garden of the world", with majestic domes, courtyards, and soaring minarets spread across the city.
