The gens Cispia was a plebeian family at Rome. Although the gens was supposedly of great antiquity, the Cispii only achieved prominence toward the end of the Republic.Dictionary of Greek and Roman Biography and Mythology, William Smith, Editor.

Origin The Cispii were probably of Hernician origin, and according to tradition came from Anagnia, a town of the Hernici, during the reign of Tullus Hostilius, the third King of Rome. A certain Cispius Laevus was said to have come to the defense of Rome while the king was engaged in the siege of Veii, and stationed his forces on one of the two summits of the Esquiline Hill. At the same time, a second force stationed itself on the other summit. These were led by a certain Oppius, who had come from Tusculum. The two peaks subsequently became known as the Cispius Mons and the Oppius Mons. In Varro, the nomen is also written Cespeus.Sextus Pompeius Festus, epitome of Marcus Verrius Flaccus, De Verborum Significatu, s.vv. Septimontio, Cispius Mons.Marcus Terentius Varro, De Lingua Latina libri XXV, v. 50, ed. Müller.Dictionary of Greek and Roman Biography and Mythology, William Smith, Editor.

Praenomina The praenomina used by the Cispii included Lucius, Gaius, and Marcus, all of which were amongst the most common names throughout Roman history.Realencyclopädie der Classischen Altertumswissenschaft.

Branches and cognomina The only cognomen of the Cispii is Laevus, meaning "left-handed" or "foolish". The surname may also be of Ligurian origin. Some of the Cispii are mentioned without a surname.D.P. Simpson, Cassell's Latin & English Dictionary (1963).Titus Livius, Ab Urbe Condita, v. 35, xxxiii. 37.Dictionary of Greek and Roman Biography and Mythology, William Smith, Editor.
