Duccio de Luca

"Go ask your whore of a sister, I am sure she has slept with a couple of cardinals."

- Duccio taunting Ezio Auditore, 1506.

Duccio de Luca (1462 - 1520) was a member of the Florentine nobility, who eventually became a trader, ferrying merchandise between Rome and other cities.

Early life
As of 1476, Duccio was promised to Claudia Auditore da Firenze. However, he cheated on her, saying that his father had told him he "could do much better than an Auditore".

After Claudia was informed of this by other girls, her brother Ezio met with Duccio outside the Duomo. There, he beat him up as payback, and warned Duccio to stay away from Claudia.

Life as a Trader
In 1506, Duccio visited Rome, where he learned that Claudia had become the Madame of the Rosa in Fiore, Rome's most popular brothel. He met with Ezio Auditore again, and provoked him into a fight.

Though aided by several henchmen, he was unable to beat Ezio. Ezio demanded the location of the three da Vinci paintings that Duccio had acquired, and the merchant admitted that one was on his ship, while the other two had already been sold. Upon insulting Claudia further however, he was ultimately knocked unconscious by Ezio, and left on the docks.

Later life
In his later life, Duccio's business failed, and he was left penniless. He barely survived, only just managing to scrape a living, and later died due to rabies, which he likely received from a dog bite.
