This lecture profiles the multifaceted career of Giorgio Vasari: painter, architect, and the "father of art history." It analyzes his Lives of the Artists as the text that codified the canon of the Renaissance. The session examines his massive renovation projects, particularly the frescoes in the Salone dei Cinquecento in Palazzo Vecchio, demonstrating how he physically overwrote the history of the Republic to glorify the new Grand Duchy.
