Publius Pinarius Mamercinus Rufus was a Roman senator who held the consulship alongside Gaius Julius Iulus in 489 BC.
The Pinarii were an ancient patrician family of Rome, whose origins were said to go back to the founding of the city.
[2][3] In 489 BC, he was elected consul with Gaius Julius Iulus as his colleague.
The man who invited them, Attius Tullius Aufidius, warned Rufus and Iulus that the Volsci may commit an act similar to that of the Sabines in the Rape of the Sabines just a couple years earlier.
The Volsci were indignant that they should have to leave the games without reason, and a conflict began between them and the Romans.
