Madonna And Child With Four Angels ('The Chellini Madonna')

In 1456, Donatello gave the piece to the Florentine physician, Giovanni Chellini Samminiati, who had cured him of illness. The relief depicts the virgin embracing the Christ Child tended by four angels, one of whom reaches out to him while another offers a dish of fruit or sweetmeats to the Virgin.

This reflects a contemporary practice of presenting gifts of food to the new mother. The back of the relief is a negative impression of its front, a feature otherwise unknown in Renaissance sculpture. According to Chellini himself, this was 'so that melted glass could be cast onto it … and make the same figures as those on the other side.' Modern glass reliefs made from casts of the reverse of the roundel have attested this claim. Much of the money needed to purchase the relief was raised through a public appeal.
