An ancient Greek marble Trojan archer sculpture from the Temple of Aphaia missing original paint (left), and a re-creation of the same polychromy sculpture based on archaeological remnants of paint found on the marble surface (right)[1] Most ancient European marble sculptures were painted.[2]
Marble has been the preferred material for stone monumental sculpture since ancient times, with several advantages over its more common geological "parent" limestone, in particular the ability to absorb light a small distance into the surface before refracting it in subsurface scattering. This gives an attractive soft appearance which is especially good for representing human skin, and which can also be polished.[3]
Of the many different types of marble the pure white ones are generally used for sculpture, with coloured ones preferred for many architectural and decorative uses. The degree of hardness is right to carve without too much difficulty, but still give a very durable result, if not exposed to acid rain or seawater.[4]
