For the ancients it was the Stygian lake, which Virgil mentions in the Aeneid, telling about Palinuro’s death.
It rises from mont Gelbison and flows through the territory of Cilento for 22 kilometres until flowing into the sea close to Capo Palinuro.
In its name, the word “river” is included. This torrent is the main right tributary of the Mingardo. It rises from Mount Antilia and flows for ten kilometres in the province of Salerno.
With its 37 kilometres, it is among Cilento main watercourses, of which it is particularly rich. It rises from the slopes of mount Cervati, 900 metres of altitude from the spring of Varco La Pela in the municipality of Sanza.
Apart from its Lucanian origin, Tanagro is the river of Cilento and Vallo di Diano National Park, because it flows into it for most of its 92 meters course.
The ancients venerated it as a water divinity and represented it with a prolific white beard and, in their hands, a vase where precious water was flowing.
The bridge linking Roscigno to Sacco in the territory of the latter crosses the Sammaro, exactly above the spring.
