The accounts of the _Opera_ have some interesting articles connected with the laying of the foundations of the revised plan. In August 1339 the Masters were called into council on the enlargement of the Duomo, as the nave was considered too short, and Ser Bindo, the notary of the guild, had to supply them with five sheets of parchment at one lire a sheet to make designs. Also two lire ten soldi were spent in bread, meat, and wine, which were sent by the guild to the priests who officiated when the first stone was laid. In March, Maestro Lando again applied to Ser Bindo for parchment to make designs, which cost him twenty-three soldi six denari. Whether these plans were accepted or not, I cannot tell--probably not--for in the following March, Lando fell ill and died. He left a son, Pietro di Lando, also in the guild, and who was naturalized Florentine when he joined that lodge. A document cited by Gaye (_Carteggio_, etc. vol. i. p. 73) shows Pietro to have worked with Giovanni di Lazzero de Como and a Buono Martini at the fortifications of Castel S. Angelo in Val di Sieve; the three architects solicited the Signoria for the pay due to them. This Pietro was the father of Vecchietta, who inherited more than his great-grandsire's talent for working metal. The next _capo maestro_ after Lando was Giovanni, son of the famous sculptor Agostino of Siena, who was, on March 23, 1340, elected for five years. He had been head of the works at Orvieto in 1337, but did not long remain there, for in 1338 we find him again in the pay of the lodge of Siena, where a document in the archives of the Hospital notes a payment for some work on April 26, to Maestro Giovanni, son of Maestro Agostino of the _Opera_, and of the parish of S. Quirico.[226]
