One might be surprised at the lenity with which the Republic judged the ringleaders of the Tiepolo-Quirini conspiracy; but it must not be forgotten that the conspirators, entrenched on the Rialto, were beyond the Doge’s power, and still threatened the safety of the city and of the Republic, which was no doubt glad to be rid of them at any price. Moreover, we have record of a pitiful episode, which shows that the Venetian government could be severe to cruelty without necessarily employing the executioner. Among the nobles who went into exile beyond Zara after the affair at Rialto was Niccolò Quirini, Marco’s son, surnamed ‘the Lame.’ His wife, who was, as we have said, the daughter of Giovanni Soranzo, joined him in his exile. At the end of four years, says Molmenti, she felt an irresistible longing to see her family again, and asked permission to return home, but it was not granted to her. Her father, however, had been made Doge in 1311, and she began the journey, trusting to his influence. No sooner had she reached Venice than she was arrested and condemned to perpetual confinement in the convent of Sta. Maria delle Vergini, in one of the most distant districts of the city. [Sidenote: _Galliccioli, vi. 58._] [Sidenote: _Giustina Renier Michiel, Origini ii. 73._] In connection with this story it should be noted that the convent in which she was imprisoned was not one of cloistered nuns. Until the end of the fifteenth century they bore the title of ‘canonesses’; they were under the government of an abbess, but took no solemn vows, wore no veils, and could even leave the convent and marry. The convent itself was under a sort of tutelage of the Doge. It had been founded and endowed at the beginning of the thirteenth century by the Doge Pietro Ziani, together with a church dedicated to the Virgin Mary, and became the common residence of many noble ladies, and of many noble girls who were educated there. The Doge conferred the investiture upon the abbess, according to the custom of those times, by means of a golden ring, and once a year he went to visit the convent. This was in the month of May; and after hearing mass the Doge went into the parlour, where the abbess received him, being dressed in a magnificent white mantle, with two veils upon her head, one white and the other black. She presented the Doge with a small bunch of flowers, set in a golden handle, for which the Doge expressed his thanks in a set form. The Doge Soranzo must have gone through this function many times while his own daughter was a prisoner in the nunnery, and not allowed to assist in the ceremony. The old building of the Vergini was destroyed by fire in 1375, but was restored with greater splendour than before as a place for educating noble Venetian girls.
