Brera Madonna. The Brera Madonna is a painting by the Italian Renaissance master Piero della Francesca, executed in 1472-1474.

The painting was executed between 1472 and 1474; the terminus ante quem is established by the absence from Federico's figure of the insignia of the Order of the Garter, which he received in the latter year.

The work represents a sacred conversation, with the Virgin enthroned and the sleeping Child in the middle, surrounded by a host of angels and saints. On the right low corner, kneeling and
