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.

Very hostile comments by Bernard Berenson in 1903 called it "a picture of unalloyed mediocrity, with scarcely a touch of charm to repay the absence of life and vigour"; this did not encourage detailed study by others.
"What they all have in common is a pronounced taste for precious effects, the highly efficacious imitation of jewels, brocades, velvets, with an illusionistic and tactile treatment based on the extensive and experimental use of oil-based binders (at the height of the reign of tempera in Florence), in open emulation of the Flemish masters".
