Aruns Egerius Tarquinius was a member of the royal family of early Rome.
While his mother was pregnant with him, Aruns died and since Demaratus was unaware of the pregnancy, he left his entire estate to Aruns' brother, Lucumo. Left with nothing, the child was aptly called Egerius, "the Needy One".
His uncle Lucumo would became King of Rome as Lucius Tarquinius Priscus.
