The altarpiece of the Coronation of the Virgin by Piero del Pollaiuolo behind the high altar in the church of Sant'Agostino, San Gimignano in Tuscany, Italy, was painted in 1483.[1] As the painter's only signed and dated work it is a key piece of evidence in the question of which paintings to attribute to Piero and which to his more famous brother, Antonio del Pollaiuolo, which has become a contentious subject in recent years.[2]
The painting is in tempera on panel, although recent technical analysis has shown that linseed oil was also used, a rather early example of oil painting for Florentine painting, found in other paintings by the Pollaiuolo brothers.[3]
