Portrait of the Katchef Dahouth, Christian Mameluke Anne-Louis Girodet de Roucy-Trioson (1767-1824)

The picture has something of this: people, portrait, man, facial hair, veil, fall, mustache, wear, music, monk, god, beard, musician, light, festival.
Perhaps it’s a painting of a man with a long white beard and a yellow turban sitting on a couch with a cane in his hand.
