Vanni, Cavalier Michael Angelo

Vanni, Cavalier Michael Angelo an Italian painter of the 17th century, was the eldest son of the cavalier Francesco Vanni, by whom he was instructed in the art. His fame rests chiefly, however, upon his invention of a new process of staining marble in imitation of mosaic. There are some of his paintings in the churches and convents of Sienna, but they are much inferior to the best productions of his father. See Spooner, Biog. Hist. of the Fine Arts, s.v.
