サン・ジョヴァンニ洗礼堂
On being released from imprisonment in 1418, Antipope John XXIII came, broken down and destitute, to Florence, and was given an asylum there by Giovanni di Bicci de' Medici, who, when the deposed Pope died in the following year, erected to his memory the tomb which is to be seen in the Florence Baptistery. When the inscription was put up (after Giovanni's death), Pope Martin V objected to the words "Quandam Papa" (former Pope) and wrote to the Signoria demanding that they should be erased. The reply was a refusal, written by Cosimo de' Medici, and couched in the words of Pontius Pilate, saying, "Quod scripsi, scripsi."
