Trinity, fresco in the Santa Maria Novella in Florence

The Trinity fresco is the most famous work of Masaccio beside the frescoes in the Cappelle Brancacci. There are various opinions as to exactly when this fresco was painted between 1425 and 1428. It was described in detail by Vasari in 1568, who emphasized the virtuosity of the "trompe l'oeil" in the architectural structure of the painting: "a barrel vault drawn in perspective, and divided into squares with rosettes which diminish and are foreshortened so well that there seems to be a hole in the wall."
