Egerius

Aruns Egerius Tarquinius was a member of the royal family of early Rome.

His father was Aruns, son of Demaratus the Corinthian and a noblewoman Princess from Tarquinii.

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.

After the surrender of Collatia at the conclusion of Tarquinius Priscus' war against the Sabines, Eqerius was left in charge of the town's garrison. His son's cognomen comes from the town.

Egerius fathered Lucius Tarquinius Collatinus, who was the husband of Lucretia.
