A screen or "transenna" in marble by Mino da Fiesole, Andrea Bregno, and Giovanni Dalmata divides the chapel into two parts. Originally these made equal space for the members of the Papal Chapel within the sanctuary near the altar and the pilgrims and townsfolk without. However, with growth in the number of those attending the Pope, the screen was moved giving a reduced area for the faithful laity. The "transenna" is surmounted by a row of ornate candlesticks, once gilt, and has a wooden door, where once there was an ornate door of gilded wrought iron. The sculptors of the "transenna" also provided the "cantoria" or projecting choir gallery.
