fragments and integrated with new additions. The original pieces are exquisite sculptural works by the school of Andrea Bregno. Pico Cellini claimed that the sculptures of the saints in the shell-headed niches had previously decorated the rear side of Bregno's old main altar which was demolished in 1627 (the front side is kept in the sacristy). This theory remains disputed because that statues might have come from other demolished monuments in the basilica like the lost Borgia tombs. The identification of the four saints are uncertain except the figure of John the Baptist (with scroll and lamb) on the baptismal font and John the Evangelist (with chalice) on the font of the holy oil. The symbols, the haloes and the hair of the figures are gilded. The shafts of the Composite pilasters are decorated with ecclesiastical symbols: different types of crosses, cardinal's hats, torches, wreathes, palm branches, lamps. The shields with the crosses on the pilasters of the aedicula of the holy oil indicate that these parts came from the Cybo chapels. On the dropped friezes there are pairs of cherub heads between bunches of fruits. Inside the niche of the baptismal font there is a relief depicting the Baptism of Jesus. The coats of arms on the plinths belong to Cardinal Flavio Chigi. Parapet The 15th-century parapet with the coats-of-arms of a Della Rovere cardinal is probably the finest in the basilica. It shows a strong similarity to the parapet of the Della Rovere Chapel. The central motifs are the coats themselves which are surrounded by wreathes of fruit and fluttering ribbons. The white marble central slabs are flanked by dwarf pillars which are decorated with different types of shields and bunches of fruits, ears and flowers. There is a cross botonny on the large shield in the middle of the right door pillar. The matching shield on the other side is empty and the pillar has a rough, unfinished surface. There are many other subtle differences between the two sides: the wreath on the left is less closely set, and it contains acorns, ears of wheat and poppy pods, the ribbons on the left have tufts at their ends while those on the right have pretty flowers sprouting. Unusually the inner side of the parapet is decorated as well. The central motif on each slab is an antique wine jug and a palm branch placed crosswise. These are
