Lorenzo Bartolini (Prato, 7 January 1777 – Florence, 20 January 1850) was an Italian sculptor who infused his neoclassicism with a strain of sentimental piety and naturalistic detail, while he drew inspiration from the sculpture of the Florentine Renaissance rather than the overpowering influence of Antonio Canova that circumscribed his Florentine contemporaries.
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.
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.
