as proto, was nevertheless responsible for oversight during construction. Construction Bon's superintendence (ca. 1514–1529) Construction began with the damaged section adjacent to the clock tower and proceeded gradually. To limit the loss of revenue to the procurators, each tenant was evicted only when it became necessary to demolish the apartment in order to continue building. Also, the new shops on the ground floor and apartments above were leased as soon as they were ready. By 1517, the first section had progressed far enough to begin work on the façade with the revetments in Istrian limestone. That same year, the first new apartment was rented out. With respect to the pre-existing structure, the layout of the new building was altered for the first 24 arcades with the insertion of a small street running parallel to the square. In contrast, the earlier layout, characterized by a series of courtyards, was retained for the remainder of the building, further away from the area damaged by the fire. This indicates that, although documents refer to the demolition of the previous structure, certain parts of it were in fact maintained and reutilized, presumably to minimize costs. Sansovino’s superintendence (1529–1538) Following the death of Pietro Bon in 1529, Jacopo Sansovino, a refugee from the Sack of Rome, was nominated in his place as proto to the procurators de supra. The final eight bays of the Procuratie Vecchie, containing five apartments, and the five bays along the western side of the square (subsequently demolished) were completed under Sansovino's direction. Architecture Layout Given financial constraints during the War of the League of Cambrai, innovation was limited to design modifications that were aimed at increasing revenue to the procurators de supra, foremost of which was the addition of a floor to increment the number of rental apartments. Also, the number of workshops and stores on the ground floor was increased by inserting a narrow street behind the row of stores that opened onto the square so that each arcade now corresponded to an individual shop. On the upper floors, the rooms in the back section, connected by suspended galleries, were destined for servant quarters associated with the principal apartments that looked onto the square. Façade The Procuratie Vecchie was the first major building erected in Venice in emulation of classical prototypes. Although many aspects of the earlier Veneto-Byzantine structure were maintained, including the decorative crenellation along the roofline and
