Brunelleschi, who had an investigating genius, himself painted the quaint constellations in the ceiling over the altar.

At the Pazzi chapel we shall find similar architecture; but there extraneous colour was allowed to come in.

Here such reliefs as were admitted are white too.
The tomb under the great marble and porphyry table in the centre is that of Giovanni di Bicci, the father, and Piccarda, the mother, of Cosimo Pater, and is usually attributed to Buggiano, the adopted son of Brunelleschi, but other authorities give it either to Donatello alone or to Donatello with Michelozzo: both from the evidence of the design and because it is unlikely that Cosimo would ask any one else than one of these two friends of his to carry out a commission so near his heart.

The table is part of the scheme and not a chance covering.

I think the porphyry centre ought to be movable, so that the beautiful flying figures on the sarcophagus could be seen.
