Fra Angelico, Perugia Triptych Angel of the Annunciation. See more below.
Late Gothic naturalism marked by cluttered description, decorative colors, extensive gilding, flattened and elongated forms, vertical perspective (rising rather than receding), and symbolic scale (figure size determined by relative importance, not position in space). The richness of colors was desired to reflect the status of the donor, since gold and certain colors cost more.
During time of artistic transition, many painters use a hybrid style. Fra Angelico adopted one point perspective while keeping many late Gothic qualities. I’m very interested now to read more about different perspectives with artists and the evolution of perspective in painting.
