The foundation in 1234 of the Dominican Monastery and Church of Santi Giovanni e Paolo (S. Zanipolo) was due, the chroniclers relate, to the piety of the Doge, who saw in a vision the oratory and neighbouring Piazza of San Danieli filled with flowers and white doves bearing on their heads crowns of gold, and two angels came down from heaven and perfumed the place with golden censers. Then a voice was heard saying: “This is the spot I have chosen for my preachers.” Thereupon the Doge made over certain marshy lands near Santa Maria Formosa to Brother Alberico of the Dominicans, and aided by papal favour and the piety of individuals the building was so far advanced by 1293 that it was ready to accommodate the general chapter of the order. The facade was finished in 1351, and after the lapse of a century the mortal remains of the founder were laid there. His simple tomb wrought with figures of doves and angels, recalling the visions, still exists on the left of the entrance. The great church and monastery of the rival order of friars, S. Maria Gloriosa dei Frari, was also begun in Tiepolo’s reign. Until that time the friars of St Francis, says Sanudo, had no monastery in this city and dwelt near S. Lorenzo, where they worked with their hands and lived by their labour and by alms. At Tiepolo’s death the electoral college increased to forty-one, chose Marin Morosini, an experienced magistrate and civil servant, as his successor. Meantime the Inquisitors had met and decided that the late Doge had been too zealous in the advancement of his sons. A new clause was therefore added to the coronation oath forbidding the Doge to ask or cause to be asked any office for any person, or to accept any charge outside Venetian jurisdiction or in Istria.
