[1] He is best known for accusing Gaius Silius of being complicit in Sacrovir's revolt and misappropriating money from the provincial government in Gaul.
Refusing to submit a plea or to defend himself, Silius declared that had he not personally kept the legions on the Rhine from avenging the murder of Germanicus, Tiberius would have lost his position as Princeps.
[2] According to an inscription, Varro was appointed curator riparum et alvei Tiberis, one of the officials responsible for public works inside the city, regulating the Tiber and the maintenance of Rome's sanitation system, with Gaius Vibius Rufus.
[3] Varro's consulate was known for several pieces of legislation, which included the lex Visellia de iure Quiritium Latinorum qui inter vigiles militaverant, and the Lex Visellia de poenis libertinorum qui ingenuorum honores usurpabant.
The first rewarded former slaves who held only Latin rights with full Roman citizenship after they served six years in the vigiles, the equivalent of police and firefighting services in the city of Rome; the second penalized libertini if they tried to pass as freeborn people (ingenui) and access privileges denied to them by their status.
