Her cult dated to the earliest period of Roman religious history, since she was one of the fifteen deities who had their own flamen, the Furrinalis, one of the flamines minores.
It is cognate with Gothic brunna ("spring"), Latin fervēre, from *fruur > furr by metathesis of the vowel, meaning to bubble or boil.
She had a sacred spring and a shrine in Rome,[2] located on the southwestern slopes of Mount Janiculum, on the right bank of the Tiber.
Excavations on the site conducted in 1910 identified a well and a system of underground channels, as well as some inscriptions dedicated to Jupiter Optimus Maximus Heliopolitanus, Agatis, and the nymphae furrinae.
This grouping is devoted to woods and running waters, which are intended as shelter and relief from the heat of the season, the canicula.
