The illustrations were made by David Roberts (1796 - 1864), a Scottish orientalist painter, member of the Royal Academy of Arts. From 1831 he traveled around Europe and the Middle East, painting landscapes characterized by topographical accuracy. Roberts used the technique of oil and watercolor, he also published books rich in illustrations. His best known publication is The Holy Land, Syria, Idumea, Arabia, Egypt and Nubia (six volumes from 1842-1849), from which the prints come.
