Funeral monument of Giuseppe Giustiniani, in polychrome marbles by the Roman School. Giuseppe Giustiniani was the brother of Cardinal Vincenzo Giustiniani and had been the last Genoese ruler of the Aegean island of Chios, which had been a family possession for centuries. In 1566 the island was lost to the Ottomans. He became a banker, and by his death in 1600 was financier to the Vatican and one of the richest men in Rome.
