Cristina Vespucci

Cristina Vespucci (born sometime in 1459), was a well-known Florentine beauty and a favorite of painters, most notably Botticelli, who used her as a model for several of his paintings. Records kept by her father's guards indicate Ezio visited her quite frequently, and that he was "unbelievably dexterous", as the guards were never able to catch him trespassing.

In addition to her looks, Cristina also seems to have been somewhat responsible for jumpstarting the career of her cousin, Amerigo. At a dinner party attended by Cristina and, among other illustrious guests, Lorenzo de' Medici, she was reputed to have been in conversation with Lorenzo and Manfredo Soderini about her cousin's brilliance as a sailor.

Well, apparently, she exaggerated his importance slightly to impress Lorenzo, and Lorenzo, charmed by her beauty, agreed to hire him. "Try Amerigo out. I bet after several years you'll have your shipping company named after him," she's reported to have joked.

Relationship with Ezio
She was both a noblewoman and a student, and one of Ezio's love interests. Ezio visits her after completing a race to the cathedral rooftops with his brother, Federico Auditore, at the beginning of the game. Ezio climbs up to her bedroom window and sleeps with her. The morning after, Cristina's father walks in on them in bed, Ezio jumps out the window, telling him to understand for a moment; her father sends guards to kill him, but eventually escapes from them.

Trivia

 * Whilst in the game her family and herself bear the name "Vespucci", in the novel Assassin's Creed: Renaissance, "Calfucci" is the name used rather than the one used in the game. In fact, the history shows that she is rather known as "Simonetta Vespucci", which leaves the name "Cristina Calfucci" as a probability of her Italian name.
 * Her relationship with Ezio is depicted to be somehow more intimate in the novel; as in contrary with what is shown in the game. Furthermore, it is told in the novel that she and Ezio love each other very deeply, which brings Ezio furious when he finds out that she has been killed by Savonarola's men.
 * She is expected to appear in Sequence 13, where Savonarola takes control of Florence.
