Yes, Cicero does mention his origin in Ad Familiares 13.11, explicitly introducing him as a Roman knight and framing the entire delegation around their shared origin from Arpinum.

While the Latin text does not give a distinct city of origin for Marcus Faucius individually, it groups him into a three-man municipal commission representing Cicero's own hometown. [1, 2]

The Context and Latin Text

In the letter, Cicero writes to Marcus Junius Brutus (then governor of Cisalpine Gaul) to recommend a delegation sent to collect public land rents owned by the town of Arpinum. [1, 2]

Cicero explicitly states the identity and origin of the group in the following passage:

"...idcirco nos legatos equites Romanos misimus Q. Fufidium Q. f., M. Faucium M. f., Q. Mamercium Q. f." [1]

Translation: "...therefore we have sent as envoys, [who are] Roman knights, Quintus Fufidius, son of Quintus; Marcus Faucius, son of Marcus; and Quintus Mamercius, son of Quintus." [1]

Details of Faucius's Origin Provided in the Letter

• Patronymic (Father's Name): Cicero identifies him as "M. f." (Marci filius), meaning Marcus Faucius, son of Marcus.
• Social Status: He is explicitly designated as a Roman knight (eques Romanus).
• Municipal Origin: He belongs to Arpinum. Cicero opens the letter by reminding Brutus that he is fiercely protective of his fellow townsmen (municipes). Because this corporate embassy is appointed by and sent on behalf of the town administration of Arpinum to manage the res publica of that specific municipium, Faucius and his fellow envoys are local Arpinate elites. [, 2, 3, 4, 5]

If you are researching the specific members of this delegation, would you like to explore Cicero's personal ties to Quintus Fufidius—whom he commends separately in the very next letter (Fam. 13.12)—or look into how Arpinum acquired public estates in Gaul? [1, 2]
