Second century AD. Cast of marble head, painted with pigments in egg tempera. The head, probably of a goddess, was found at the Esquiline hill, Rome. The head was found in the 1880s and preserves numerous colour traces. Its marble surface is highly polished and has remains of a uniformly applied pigment for the skin. A carbon black under-drawing was used to define facial features such as the eyes. Red ochre was used for shadowed areas in the hair, and red madder lake defined the nostrils and the inside of the mouth.
