The process of soap-making was developed in the earliest antiquity in the Levant region of which Aleppo was a main city. Following the decline of the Roman Empire, soap was reintroduced and spread in the West by 12th century Crusaders. Emmanuel Tussore sculpts then photographs this fragile and malleable organic matter. In his hands, the Aleppo Soap - the oldest soap in the world - shifts from the refined gesture of the civilized man to become the symbol of a destructive and brutal force. Its ruins suggest the characters of a mysterious alphabet telling of absence, loss, exile, thus questioning the fundamental notions of humanism.
