Pistoia is supposed to have been founded by the soldiers of Catiline. Brunetto Latini, Tresor , I i 37, says:⁠—

“They found Catiline at the foot of the mountains and he had his army and his people in that place where is now the city of Pestoire. There was Catiline conquered in battle, and he and his were slain; also a great part of the Romans were killed. And on account of the pestilence of that great slaughter the city was called Pestoire.”
