In ancient Rome, the Ager Vaticanus ([ˈa.ɡɛr waː.t̪iːˈkaː.n̪ʊs], "Vatican Field") was the alluvial plain on the right (west) bank of the Tiber. It was also called Ripa Veientana or Ripa Etrusca, indicating the Etruscan dominion during the archaic period.[1] It was located between the Janiculum, the Vatican Hill, and Monte Mario, down to the Aventine Hill and up to the confluence of the Cremera creek.[1]
