This pair of busts is among Duquesnoy's most popular creations. Bellori records that a pair of terracotta heads of the young Christ and the Virgin were in the collection of Francesco Barberini. From these, Duquesnoy cast and chased versions in silver for Queen Henrietta Maria of England and for Cardinal Camillo Massimi (G. P. Bellori, Le vite de'pittori, scultori et architetti moderni, Rome,. 1672, p. 283). Bronze examples are in the Galleria Estense, Modena and the Kunsthistoriches Museum, Vienna.
