Artoria gens

The gens Artoria was a minor plebeian family at ancient Rome. Few members of this gens are mentioned in history, but a number are known from inscriptions. Under the later Empire at least some of them were of senatorial rank.
Origin.
At least two distinct linguistic origins have been proposed for the nomen "Artorius". Schulze, Herbig, and Salomies propose that the name is derived from the Etruscan praenomen "Arnthur", perhaps Latinized as "Artor". Other scholars have proposed a Messapic origin, identifying a nomen "Artorres", from an earlier "Artas", with a Messapic possessive suffix "-or", of uncertain meaning. Some scholars have suggested that "Artorius" might be the origin of the Welsh / Cornish name "Arthur".
Praenomina.
The chief praenomina of the Artorii were "Lucius", "Gaius", "Marcus", and "Quintus", four of the most common names throughout Roman history. Lesser-used praenomina of the Artorii included "Gnaeus", "Sextus", and "Titus", and there are a few examples of other names.
Branches and cognomina.
The Artorii do not appear to have been divided into distinct families, but a number of them used common surnames, such as "Secundus", typically designating a second or younger child, and its derivatives.
