Having then entered on that office, he began to occupy himself with every care, both with regard to buildings and in the management of the papers and of the books that he held by virtue of his office, acquitting himself with all possible diligence in the affairs of the Church of S. Marco, of the Commissions, which are a great number, and of the many other matters that are in the charge of those Procurators; and he showed extraordinary lovingness towards those Signori, in that, having turned his whole attention to benefiting them and to directing their affairs to the aggrandizement, embellishment, and ornamentation of the church, the city, and the public square (a thing never yet done by any other in that office), he provided them with various advantages, profits, and revenues by means of his inventions, with his ingenuity of brain and readiness of spirit, yet always with little or no expense to the Signori themselves. Among which benefits, one was this; in the year 1529 there were between the two columns in the Piazza some butchers' stalls, and also between the one column and the other many wooden cabins to accommodate persons in their natural necessities--a thing most filthy and disgraceful, both for the dignity of the Palace and of the Piazza Pubblica, and for the strangers who, coming into Venice by way of S. Giorgio, saw first of all on arrival that filthiness. Jacopo, after demonstrating to the Prince Gritti the honourable and profitable nature of his design, caused those stalls and cabins to be removed; and, placing the stalls where they now are and making certain places for the sellers of herbs, he obtained for the Procurators an additional revenue of seven hundred ducats, embellishing at the same time the Piazza and the city. Not long afterwards, having perceived that in the Merceria (on the way to the Rialto, near the Clock), by removing a house that paid a rent of twenty-six ducats, a street could be made leading into the Spadaria, whereby the rent of the houses and shops all around would be increased, he threw down that house and increased their revenues by one hundred and fifty ducats a year. Besides this, by placing on that site the hostelry of the Pellegrino and another in the Campo Rusolo, he brought them in another four hundred ducats. He obtained for them similar benefits by the buildings in the Pescaria, and, on divers other occasions, by many houses and shops and other places belonging to those Signori, at various times; insomuch that the Procurators, having gained by his care a revenue of more than two thousand ducats, have been rightly moved to love him and to hold him dear.
