Sibidiena gens

The gens Sibidiena, sometimes written Sabidiena, was an obscure plebeian family at ancient Rome. No members of this gens attained any of the higher offices of the Roman state, but several are known from inscriptions.

Origin
The nomen Sibidienus belongs to a class of names ending in -enus, typically derived from other gentilicia, or sometimes from cognomina. Sibidienus would seem to be derived from Sabidius, or perhaps from its derivative, Sabidianus. Gentilicia of this type were common in Umbria and Picenum, and in fact most of the Sibidieni known from inscriptions seem to have lived at or near Tuficum in Umbria, from which it appears that the Sibidieni may have been of Umbrian origin, although the surname Sabinus borne by some of the family suggest that they may have been Sabines.

Praenomina
The main praenomina of the Sibidieni were Lucius and Gaius, the two most common names throughout all periods of Roman history. It also appears that the Sibidieni at one time used Spurius, a praenomen that had been common in Republican times, but which had become increasingly scarce, and finally disappeared under the early Empire.

Branches and cognomina
The only distinct family of the Sibidieni lived at Tuficum in Umbria, but they do not appear to have been divided into separate branches. Sabinus, the only surname known to have been passed down among the Sibidieni, belongs to a class of cognomina typically indicating the place of origin of an individual or family, and suggests that the Sabidieni either were, or claimed descent from the Sabines. Maximus, borne by one or two of the family, was typically given to an eldest son, or bestowed on someone who had earned great honor or distinction. Scaeva, borne by an ancestor of the Sabini, originally designated someone who was left-handed, but could also refer to someone particularly lucky, or unlucky.

Members

 * Lucius Sibidienus, named in an inscription from Tuficum in Umbria, along with Gaius Sibidienus Maximus.
 * Spurius Sabidienus (Falisleius?), the master of Artemo, a slave named in an inscription from Minturnae in Latium.
