Michele Giambono was an Italian painter of the Early Renaissance in Venice. Giambono’s style, in general, remains archaic and iconic, and seems generally unaffected by Florentine experimentation with perspective and dimensionality of figures. He designed some of the mosaics in the Mascoli chapel in the church of Saint Mark’s Basilica.
