Eustache de Lorey
Eustache de Lorey was a French diplomat, archaeologist and historian of Islamic art, and collector who was the director of the French Institute of Archaeology and Muslim Art at Damascus (later called the French Institute of Damascus) between 1922 and 1930. He was a mysterious figure, and his birth and death dates are not known. His formal education is little documented, but he nonetheless made contributions to the study of Arabic epigraphy and Islamic manuscripts. His greatest achievement was the 1926 discovery of the Ummayad mosaics of the Great Mosque of Damascus.
