The subject of this painting has nothing to do with the Golden Legend, this
is an addition by Piero. The classical architecture is present once again with
the elegant column in the centre. The symmetry of proportions is broken by vanishing
point, placed not in the centre but to the right, behind the Virgin. There is
great attention to even the smallest detail, brought out by the reflections
of the light. From the transparent veil that covers Mary's head, to the pearls
that decorate her dress, from the wood intarsia on the door, to the shadows
that are projected on the white marble surfaces, there are many new elements
that will be further developed in Piero's later works.
