De l'art chrétien
De l'art chrétien is an 1874 Paris study of Christian art by the French writer A.-F. Rio, published by Bray et Retaux for readers of art history and religious iconography. Its single picture is a dark engraved plate of a robed figure in profile holding a large tablet or slab, set against a deep recessed niche. A designer might take its strong black-and-white hatching and dramatic side lighting as a model for high-contrast tonal shading.
