In his Barometro series, Italian sculptor Giacomo Ravagli exhibits marbles with architectural heritage, such as giallo siena which lines the floor of the Duomo di Siena, as abstract sculptures. The bases of his luxurious floor and table lamps are cut from the highest calibre of Italian marble into radical angles, mirrored in the overhead brass lampshades. Just as Michelangelo saw his statues living pre-formed within his marble blocks, so too does Ravagli work away at the stone until he achieves those perfect Renaissance qualities of scale and proportion.
