Jacopo, a nephew of Tommaso, remained in Italy, and bowed his neck to the yoke of the Medici. He was made a Senator in 1561 by Cosimo I. and occupied himself, as did also his two sons, in adorning the Guadagni palace near the Duomo. His grandson, Pierantonio, began the splendid gallery, the library and the museum of antiquities, which became famous in the XVIIIth century and in the beginning of the XIXth, after his father had bought the splendid old palace of the Dei. Ortensia Guadagni married a nephew of Pope Leo XI. and after his death became lady-in-waiting to Vittoria della Rovere, Grand Duchess of Tuscany, whose education she had superintended. Created a Marchioness in her own right, an unheard-of thing in the Grand Duchy, she was invested with the feudal estate and castle of S. Leolino del Conte, with the obligation of furnishing sixty-nine soldiers to the State, and was allowed to leave her title to her brother Tommaso’s eldest heirs male. He it was who employed Gherardo Silvani to build the palace which afterwards passed into the possession of the Dukes of San Clemente (see p. 303), and his son Francesco was a patron of the arts and an intimate friend of Salvator Rosa. Alessandro, great-nephew of the Tommaso Guadagno who settled in France, assassinated Andrea Davanzati in 1566, and was condemned to death _in contumaciam_. After some years Catherine de’ Medici obtained his pardon from her uncle the Grand Duke Francesco I., and he returned to Florence, where he built, after the design of Gherardo Silvani, says Passerini, a fine palace on the site of the old houses of his family on the Piazza del Duomo, which now belongs to the Marchese Strozzi of Mantua. Baldinucci, however, only mentions the coat-of-arms on the palace as being the handiwork of Silvani. Marquess Neri Guadagni, who died in 1862, left an only daughter, married to Marchese Dufour Berte, whose son now owns the great palace in Piazza S. Spirito. PALAZZO GUICCIARDINI _Via Guicciardini. No. 13._ This gloomy large palace was entirely rebuilt by Gherardo Silvani for the Guicciardini, “changing it from the old to the modern form and creating a fine staircase,” writes Baldinucci. It stands on the site of several houses belonging to the Benizzi, where S. Filippo Benizzi, General of the Servite Order, who out of humility declined the Papal tiara, was born in 1233.
