This is the centre of an altarpiece commissioned by a Pisan notary, Ser Giuliano degli Scarsi, for the chapel of Saint Julian in Santa Maria del Carmine, Pisa. The grapes the Child eats refer to the blood shed on the cross and the wine of the Last Supper. The surface is disfigured by losses and old retouchings and was originally more decorative: the Virgin’s dress was a translucent red over silver leaf, which has now dulled.
