Among the plebeian branches of the Papiria gens, the most important was that surnamed Carbo, referring to a piece of coal or charcoal; metaphorically, something black, or of little value. The Papirii Carbones appear in the first half of the second century BC, and continued down to the time of Cicero. Paetus, the surname of Cicero's plebeian friend, referred to a mild defect of vision, variously described as "blink-eyed", or "squinty". This common cognomen implied a lesser deficit than Strabo, "squinty", Luscus, "one-eyed", or Caecus, "blind", and could even be regarded as endearing; it was an epithet of Venus.
