The Duchess also made much use of Baccio in the Pitti garden, where she had caused to be constructed a grotto full of tufa and sponge-stone formed by the action of water, and containing a fountain; and for this Baccio had caused his pupil, Giovanni Fancelli, to execute in marble a large basin and some goats of the size of life, which spout forth water, and likewise, for a fish-pond, after a model made by himself, a countryman who is emptying a barrel full of water.

After his departure, the ruinous state of the central cupola requiring immediate attention, Lodovico invited Luca Fancelli, the chief architect of the Gonzagas at Mantua, to visit Milan, and by his advice Leonardo, Bramante, and other leading masters were invited in 1487 to design models for a new cupola.

The builder of this palace was Luca Fancelli, an architect of Florence, who erected many buildings for Filippo, and one for Leon Batista Alberti, namely, the principal chapel of the Nunziata in Florence, by order of Lodovico Gonzaga, who took him to Mantua, where he made many works and married a wife and lived and died, leaving heirs who are still called the Luchi from his name.

For Pietro Urbano, of Pistoja, his pupil, was a man of talent, but would never work hard. Antonio Mini had the will but not the brain, and hard wax takes a bad impression. Jacopo l’Indaco and Mineghella were boon companions of the master. A stone-cutter Domenico Fancelli nicknamed Topolino, Pilote the goldsmith, Giuliano Bugiardini the painter, were of this company.

What would not the world give for one of them, even though Michelangelo is said to have burst his sides with laughing at the man's stupidity! Another familiar of the same sort was a certain stone-cutter called Domenico Fancelli, and nicknamed Topolino. From a letter addressed to him by Buonarroti in 1523 it appears that he was regarded as a "very dear friend."

Caradosso was sent to conduct Martini from Siena, while Gaffuri, Professor of Music, escorted Fancelli from Mantua by the duke's orders, and both masters were richly rewarded for the pains and presented with silken vests and clothes for their servants over and above the pay to which they were entitled.

In order to strengthen their hands and satisfy himself, Lodovico invited Luca Fancelli of Mantua and Francesco Martini of Siena to decide on the respective merits of the models already prepared.
