The Santa Cecilia Museum Foundation was established in 2002 by Lorenzo Ronzoni, who made available his impressive collection of musical instruments, including a large number of antique mechanical organs of the 1600s, 1700s and 1800s, as well as a series of harpsichords and fortepianos documenting the technological and stylistic evolution of the piano, eminent symbol of Western musical culture. The museum proceeds in illustrating the development of the piano with a two-register Italian harpsichord from the second half of the seventeenth century featuring an eighteenth-century oil painting of the Roman school on the inside of the lid. Also on display is a rare example of a portable organ of 1686 by Carlo Traeri, “positive” organ of 1756 by Augustine Traeri, two fine seventeenth-century instruments from the Emiliano and central regions of Italy, a magnificent example of the art in Naples of 1742 by Domenico Magino and an impressive Sicilian organ of 1771 by Gaetano Platania.
