The Pinarii are mentioned under the kings, and members of this gens attained the highest offices of the Roman state soon after the establishment of the Republic, beginning with Publius Pinarius Mamercinus Rufus, consul in 489 BC.
He taught them a form of worship, and instructed them in the rites by which he was later honored; but due to the tardiness of the Pinarii to the sacrificial banquet, Hercules assigned them the subordinate position.
[2][3][4][1] The extinction of the Potitii was frequently attributed to the actions of Appius Claudius Caecus, who in his censorship in 312 BC, directed the families to instruct public slaves in the performance of their sacred rites.
[1] The family of the Pinarii Mamercini, all of whom bore the agnomen Rufus, meaning "red", derived their surname from the praenomen Mamercus, which must have been borne by an ancestor of the gens.
[16][17] Natta or Nacca, referring to a fuller, was the surname of an old and noble family of the Pinarii, which flourished from the fourth century BC into imperial times.
