Roscia gens

The gens Roscia (Rōscia), probably the same as Ruscia, was a plebeian family at ancient Rome. Members of this gens are mentioned as early as the fifth century BC, but after this time they vanish into obscurity until the final century of the Republic. A number of Roscii rose to prominence in imperial times, with some attaining the consulship from the first to the third centuries.

Origin
The nomen Roscius is of uncertain origin; Chase suggests a possible derivation from roscidus, dewy or sprinkled with dew, and classifies the name with those that either originated at Rome, or cannot be shown to have come from anywhere else. The first of the Roscii appearing in history was a Roman ambassador, but the later Roscii may have been provincials; there was an important family of this name at Ameria, an Umbrian town not far from the border of Latium, which held the status of a municipium, and perhaps acquired Roman citizenship as early as 338 BC, at the conclusion of the Latin War.

Praenomina
The main praenomina of the Roscii were Lucius, Marcus, Quintus, Sextus, and Titus.

Branches and cognomina
The cognomina of the Roscii during the Republic were Fabatus and Otho. Fabatus seems to be derived from faba, a bean, also the root of the nomen Fabia, and suggests that the ancestors of the Roscii were engaged in agriculture. Otho is better known as a surname of the Salvia gens. Gallus, a cockerel, appears in a commentary on Cicero as a surname of the actor Quintus Roscius, but the name is not found in other sources. Other cognomina of the Roscii include Capito, indicating someone with a large head; Magnus, great; and Regulus, a prince, a diminutive of rex, a king.

In imperial times two distinct families of the Roscii came to prominence; one bearing the surname Murena, an lamprey, well known from a family of the Licinii. This family flourished in the late first and early second centuries, and one of them bore the additional surname Lupus, a wolf. The other stirps bore the cognomen Aelianus, probably indicating descent from a family of the Aelii through the female line. This family obtained several consulships beginning at the end of the first century, and continuing into the third.
