This painting shows the synthesis of trends that formed
the style of Botticelli's painting. The figure of the Christ
Child reaches from his mother's lap to bless the bunch of
grapes and stalks of grain held out to him by the angel,
symbolizing the sacrament of the Eucharist (the bread and
wine that become the body and blood of Christ), in a more
explicit manner than the traditional one of the pomegranate
used by the Florentine painters of the early fifteenth
century.
Once again there is the influence of Lippi and Verrocchio
in this painting, most notably in the landscape and
background of the scene.
