The Tinna (modern Ténna) flows from the eastern slopes of the Sibillini Mountains into the Adriatic Sea between the municipalities of Porto Sant'Elpidio and Fermo. The Latin toponym Tinna may derive from that of Tinia, the Etruscan sky-god who was equivalent to the Greek god Zeus and the Roman god Iuppiter.
