Agrippa is a Latin praenomen, or personal name, which was most common during the early centuries of the Roman Republic.
It was also the name of one of the legendary kings of Alba Longa, Agrippa Silvius, whose descendants came to Rome following the destruction of that city during the reign of Tullus Hostilius.
Roman scholar Marcus Terentius Varro listed Agrippa as one of several archaic praenomina that had passed out of use by the 1st century BC.
Gaius Plinius Secundus speculated that it was originally used for a child who was born feet-first (a breech birth).
With the gradual abandonment of the Roman nomenclature system, Agrippa once again became a personal name, surviving into modern times.
