Ambrogio Lorenzetti, Madonna and Child with St Nicholas and St Proculus

Ambrogio Lorenzetti’s Madonna and Child with St Nicholas and St Proculus is also known as the San Procolo Triptych, because it was specially painted as an altarpiece for the Church of San Procolo in Florence. After the church was deconsecrated in 1778, the triptych was dismembered and the predella was lost. The two side panels entered the Uffizi Gallery in 1914, while the Madonna and Child found its way onto the art market. The triptych was united in 1959, when the central panel was donated to the Uffizi Gallery by its owner, American art historian Bernard Berenson (a Lithuanian Jew who was born Bernhard Valvrojenski in Butrimonys near Vilnius in 1865).
