Calidia gens

The nomen Calidius is probably derived from the Latin adjective calidus, which may be translated as "warm, hot, fiery," or "passionate".^[2]

The earlier Calidii are known to have used the praenomina Quintus, Gnaeus, and Marcus. Under the Empire the names Publius and Titus are also found.^[1][3]

The Calidii of the Republic are not known to have been divided into families. In imperial times, a family of this gens bore the surname Severus.^[3]

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