The gens Ceionia or gens Caeionia or the Caeionii family was an ancient Roman senatorial family of imperial times. The first member of the gens to obtain the consulship was Lucius Ceionius Commodus in AD 78. The rise of this family culminated in the elevation of the emperor Lucius Verus, born Lucius Ceionius Commodus, in AD 161.

Origin

The Ceionii were probably of Etruscan origin. Their nomen resembles other Etruscan names, such as Cilnius, and the family does not appear in history before the first century. The historian Aelius Spartianus wrote that they came from Etruria, or perhaps from the town of Faventia, which was itself of Etruscan origin.

Praenomina

The praenomina used by the Ceionii were Lucius, Gaius, and Marcus.

Branches and cognomina

The most illustrious family of the Ceionii bore the cognomen Commodus, meaning "friendly, obliging," or "pleasant." The agnomen Verus, meaning "true", was borne by some members of this family. Many other surnames occur, some of which were ordinary cognomina, such as Rufus, meaning "red" or "reddish," or Bassus, "stout". However, as with many families of imperial times, many surnames were acquired from other families to whom the Ceionii were related or otherwise politically connected. Postumus, a surname belonging to the father of the emperor Albinus, is derived from the praenomen Postumus, referring to a youngest child, although a popular false etymology derived it from post humus, "after burial", meaning a child born after his father's death. In a letter referred to by the historian Julius Capitolinus, Ceionius Postumus claimed to be a descendant of the ancient patrician house of the Postumii, whose nomen was itself derived from the praenomen Postumus. Ceionius named his son Albinus, supposedly in reference both to the extraordinary whiteness of his skin, and to the noble family of the Postumii Albini; however, several other members of the gens also bore the surname Albinus.
