Bartolomeo d'Alviano (1455 – 1515) was a member of the Assassin Order, and the leader of Venetian and Roman mercenaries. Being a skilled and loyal fighter, as well as being in command of a fair amount of mercenaries, Bartolomeo was an important asset to the Assassin Order.
During his time in Venice, he befriended Ezio Auditore, later Mentor of the Italian Assassins, and together they managed to reconquer the Castello District, Bartolomeo's home, from Silvio Barbarigo, a Templar noble who had claimed it for himself. Bartolomeo was also present when Ezio was officially initiated into the Order. When Ezio infiltrated the Vatican, Bartolomeo assisted, causing trouble in Rome to keep the guards from stopping Ezio.
Bartolomeo and Ezio met again in Rome, where Bartolomeo and his wife, Pantasilea Baglioni, had settled in the Caserma di Alviano. There, Bartolomeo fought with both the Borgia forces and the French soldiers led by Octavian de Valois. Along with Ezio, he managed to weaken the Borgia enough for the Assassins to liberate the city.
Bartolomeo also served as the General of several Italian armies, being renown for his determination and swordsmanship. He fought in the Battle of Agnadello, which he lost. Upon being released, he continued his military career, until he finally fell while besieging Ghedi.
