From 1515 To 1535
This is probably the "natural seeming and very beautiful" portrait of a canon from Pisa Cathedral that the biographer Giorgio Vasari describes in his Life of Andrea del Sarto.
The canon was a close friend of the artist during his last years and helped him to secure his last commissions.
He is shown holding a small prayer book, or Book of Hours.
Madonna and Child with Saints
The painting is of the saints Catherine of Alexandria, Leonard, Augustine, and Apollonia.
The painting was painted in about 1520 for the Augustinian church of San Leonardo nel Monte outside Verona.
The painting was described at length by the sixteenth-century biographer Giorgio Vasari, who especially admired the landscape and enormous laurel tree.
The painting is set in a richly furnished interior that would have been familiar to sixteenth-century viewers.
The painting is influenced by Italian art, and Joos appropriated a new canon of beauty, a new repertory of rhetorical gesture, and a striking grace of movement in his figures.
