Sosia gens

The praenomina associated with the Sosii of the Republic were Quintus, Titus and Gaius. The Sosii Falcones of imperial times used Quintus and Marcus. All of these were extremely common throughout Roman history.

The original Italian members of the gens were probably of Picentine origin.^[2][3] A distinct family of Sosii appears prominently in the Senate during the reign of Emperor Domitian onward, and its progenitors seem to have been easterners. It is likely that an ancestor of theirs received Roman citizenship from Gaius Sosius, when the latter had served as governor of Syria and Cilicia during the time of the Second Triumvirate.^[4]

The Sosii of the Republic bore no cognomina, and were not divided into distinct families. In the second century, however, a family bearing the name of Sosius Falco appears, descended from a daughter of Quintus Sosius Senecio, consul in AD 99 and 107, who married Quintus Pompeius Falco, consul in 109. Senecio, the original surname, was derived from senex, an old man, while Falco, a falcon, was inherited from the Pompeii; it frequently denoted someone whose feet resembled talons; the modern expression is "pigeon-toed".^[5] Priscus, borne by some of the same family, was a common surname meaning "old" or "elder".^[6]

This list includes abbreviated praenomina. For an explanation of this practice, see filiation.

• Quintus Sosius, an eminent eques from Picenum, who confessed to the crime of burning the public records' office in 83 BC.^[2]
• Titus Sosius, grandfather of the consul Gaius Sosius, and probably father of the praetor of 49 BC.^[7]
• Gaius Sosius T. f., quaestor of the consul Manius Lepidus in 66 BC, and praetor in 49 when, on the outbreak of the Civil War, he at first supported Pompeius, but submitted to Caesar upon the former's flight from Italy. He was father of the consul of 32 BC.^[8][9][10]
• Gaius Sosius C. f. T. n., a staunch partisan of the triumvir Marcus Antonius, celebrated a triumph in 34 BC for installing Herod as king of the Jews. Consul in 32, he openly opposed Octavian, and commanded part of Antonius' fleet at Actium, but was later pardoned by Octavian.^{[11][12][13][14][15][16][17][9][18]}
• Sosius, and his brother, were booksellers at Rome, mentioned by Horace. They may have been freedmen of the senatorial Sosii.^[19][20][21]
• Sosia Galla, the wife of Gaius Silius, consul in AD 13 and legate under Germanicus, was a close friend of Agrippina. In AD 24, Sosia and her husband were accused by Sejanus of corruption and plundering the provinces during Silius' command in Germany. Believing his cause hopeless, Silius took his own life, while Sosia was banished from Rome.^[22][23]
• Sosia Maxima, a Vestal Virgin.^[24][23]
• Sosius Papus, a friend of Hadrian, was honoured with a statue by the emperor Trajan. He might perhaps be the same person as the consul Quintus Sosius Senecio.^[25][26][27]
• Sosia Juncina, wife of Quintus Antonius Isauricus, consul suffectus in AD 140, dedicated an altar to the goddess Fortuna at Eboracum, where her husband was stationed as legate of the sixth legion in the 130's.^[28][23]
