Entry from "A Florentine Diary" by Luca Landucci:
The king went together with the Signoria to hear mass at Santa Maria del Fiore and here he swore to observe the articles which had been drawn up, and which were as follows: that we should lend him 120 thousand florins, giving him 50 thousand florins now, and the rest before the end of July 1495; and that he should leave and give back to us the forts of Pisa and all the others; and leave our territory free and unmolested; and that Piero de' Medici should be confined to boundaries 100 miles away from Florence; and that the price of 2000 florins placed upon his head should be taken off, and also off his brothers'. All this he swore to observe, on the altar of Santa Maria del Fiore, before Christ Jesus, on the word of a king.(1)
(1) These articles had been signed the preceding day in the palace of the Medici, where the king was quartered. The Marquis Gino Capponi published them in the Archivio Storico Italiano, I Serie, vol. I., pp. 348-75. There are twenty-seven articles, and the last twelve regard entirely the persons and interests of the Medici.
