Now, after being created Pontiff in the year 1431, Pope Eugenius IV, hearing that the Florentines were having the doors of S. Giovanni made by Lorenzo Ghiberti, conceived a wish to try to make one of the doors of S. Pietro in like manner in bronze. But since he had no knowledge of such works, he entrusted the matter to his ministers, with whom Antonio Filarete, then a youth, and Simone, the brother of Donatello, both sculptors of Florence, had so much interest, that the work was allotted to them. Putting their hands to this, therefore, they toiled for twelve years to complete it; and although Pope Eugenius fled from Rome and was much harassed by reason of the Councils, yet those who had charge of S. Pietro contrived to prevent that work from being abandoned. Filarete, then, wrought that door in low-relief, making a simple division, with two upright figures in each part--namely, the Saviour and the Madonna above, and S. Peter and S. Paul below; and at the foot of S. Peter is that Pope on his knees, portrayed from life. Beneath each figure, likewise, there is a little scene from the life of the Saint that is above; below S. Peter, his crucifixion, and below S. Paul, his beheading; and beneath the Saviour and the Madonna, also, some events from their lives. At the foot of the inner side of the said door, to amuse himself, Antonio made a little scene in bronze, wherein he portrayed himself and Simone and their disciples going with an ass laden with good cheer to take their pleasure in a vineyard. But since they were not always at work on the said door during the whole of those twelve years, they also made in S. Pietro some marble tombs for Popes and Cardinals, which were thrown to the ground in the building of the new church. [Illustration: BRONZE DOORS (_After =Antonio Filarete=. Rome: S.
