This is a classic watercolor work created by famous Scottish painter David Roberts in 1838, depicting a group of Nubians in the desert area of Wady Kardassy, Egypt. The figures wear traditional ancient Egyptian costumes, some hold spears and shields, while a woman carries a pottery jar on her head. The distant dunes show remaining pillars of ancient ruins, the warm yellow tone is full of profound historical sense, it is a precious painting recording 19th century Egyptian Nubian humanistic features.
