text: # Cilnia gens
  
  The gens Cilnia was an Etruscan family at ancient Rome, from the late Republic into imperial times. This gens is best known from Gaius Cilnius Maecenas, a trusted friend and advisor of Augustus, who was famous for his immense wealth and patronage of the arts. At least two of the Cilnii obtained the consulship under the Empire.
  
  ## Origin
  
  The Cilnii hailed from the Etruscan city of Arretium, where they were amongst the local nobility, and had once held the title of Lucumo, or king. Their nomen was originally written Cfelne or Cfenle, which was subsequently Latinized as Cilnius, much as the Etruscan Lecne became Licinius. The Cilnii supported Roman interests in Etruria, and were expelled from Arretium in 301 BC, but regained their position with Roman aid.
  
  ## Branches and cognomina
  
  The only family of the Cilnii to achieve prominence under the Republic bore the cognomen Maecenas, sometimes found as Maecaenas or Maecoenas. They claimed descent from Lars Porsena, the legendary king of Clusium, who played a prominent role in the early history of the Roman Republic. The name may be derived from a place, perhaps the same where the wines called the vina Maecenatiana were produced. On Etruscan funerary urns, the names of Cilnius and Maecenas occur separately, but never together, from which Müller concludes that these families did not unite until a later period. At Rome, the family was part of the equestrian order. Other surnames were borne by the Cilnii of Imperial times, including Paetinus, a diminutive of Paetus, originally given to someone bleary-eyed, and Proculus, an ancient praenomen that had fallen out of use, but was revived as a common surname. It seems to have been a diminutive of procus, a prince or nobleman, although by the time of Varro a popular etymology held that it originally designated a child born when his father was far from home.
