The Disputation on the Trinity

The Disputation on the Trinity is an oil-on-canvas painting by the Italian Renaissance artist Andrea del Sarto, created c. 1517, now in the Galleria Palatina in Florence.

Seated in the foreground are Saint Sebastian and Mary Magdalene, the latter modelled on the artist's wife Lucrezia del Fede.

Behind them stand four male saints, from left to right Augustine of Hippo (with his bishop's staff), Saint Lawrence (with the gridiron of his martyrdom), Peter Martyr (holding a book, wearing a Dominican habit and with a sword in his head) and Francis of Assisi (in his order's habit and bearing the stigmata).

All the monastery's goods were moved to the church of San Jacopo tra Fossi for safety in 1529 just before the Siege of Florence.

The date painted on the step is a later addition, but Vasari's Lives of the Artists records it was produced after the Madonna of the Harpies (1517), and this dating is generally accepted by comparison with other works from that time.
