Gaius Calpurnius Piso Frugi

Reading notes

• Ad Atticum 1.3 §3 Tullia we have betrothed to Gaius Piso son of Lucius, of the Frugi

  C. Calpurnius Piso Frugi, of the upright ("Frugi") branch of the Calpurnii, became Cicero's first son-in-law; he married Tullia c. 63 and died in 57 BC while Cicero was in exile. The filiation "L. f." (son of Lucius) fixes which Piso is meant.

• Ad Atticum 2.24 §3 my son-in-law Piso

  C. Calpurnius Piso Frugi, husband of Cicero's daughter Tullia, distinct from the consular governors of the same name. He died young in 57 BC while Cicero was in exile.

• Ad Familiares 13.31 §1 for he was on the closest terms with my son-in-law, Gaius Piso

  Cicero's son-in-law Gaius Calpurnius Piso Frugi married Tullia around 63 BC and died in 57 BC; the fact that Cicero still mentions the connection shows it remained socially operative even after Piso's death. The shared tie to the deceased Piso is Cicero's way of vouching for the depth of the friendship.

• Ad Familiares 14.3 §3 with such a son-in-law present

  C. Calpurnius Piso Frugi, the husband of Cicero's daughter Tullia, who worked tirelessly for his father-in-law's recall during the exile. He died in 57 BC before Cicero's return.

• Ad Quintum Fratrem 1.4 §2 our Piso

  C. Calpurnius Piso Frugi, Cicero's son-in-law and Tullia's husband, who worked devotedly for the recall and died young in 57 BC. Not the consul L. Piso, an enemy.
