 From the cornice hangs a bronze semblance of the scalloped and tasselled border that typically trimmed the papal baldacchino.The structure is decorated with detailed motifs including heraldic emblems of the Barberini family (Urban VIII was born Maffeo Barberini) such as bees and laurel leaves.The underside of the canopy and directly above the officiating pope is a radiant sun – another emblem of the Barberini – within which is the Holy Spirit.
