 The fresco 's current appearance is not identical to the version redone by Uccello . The frame with candelabra @-@ pattern decorations was added by Lorenzo di Credi in 1524 , when he restored the fresco . In 1688 , it was restored again , in refurbishments celebrating the marriage of Ferdinand de ' Medici and Violante of Bavaria . The fresco was restored and transferred to canvas in 1842 by Giovanni Rizzoli and moved to the west wall of the Duomo , only to be moved back to the north wall in 1947 , after being mounted on a masonite and aluminum support . It has been argued , based on Uccello 's alleged use of Masaccio 's eye @-@ point perspective , that the painting was originally five feet higher than it stands today . The fully restored fresco was also briefly taken down in 1953 – 1954 to be shown in the " Quattro Maestri " ( " Four Masters " ) exhibition in Florence .
