In the myth and religion of ancient Rome, Juturna, or Diuturna, was a goddess of fountains, wells and springs, and the mother of Fontus by Janus.

Mythology

Juturna was an ancient Latin deity of fountains, who in some myths was turned by Jupiter into a water nymph – a Naiad – and given by him a sacred well in Lavinium, Latium, as well as another one near the temple to Vesta in the Forum Romanum. Her original home was said to be on the mythological river Numicius. The pool next to the second well was called Lacus Juturnae. A local water nymph or river-god generally presides over a single body of water, but Juturna has broader powers which probably reflect her original importance in Latium, where she had temples in Rome and Lavinium, a cult of healthful waters at Ardea, and the fountain/well next to the lake in the Roman forum. It was here in Roman legend that the deities Castor and Pollux watered their horses after bringing news of the Roman victory at the Battle of Lake Regillus in 496 BC (Valerius Maximus, I.8.1; Plutarch, Life of Aemilius Paulus, 25.2, Life of Coriolanus, 3.4). A temple was erected in her honour after the first Punic war.

Cult

Holloway has argued that the goddess shown carrying a winged helmet on early Roman coinage is Juturna, but her iconography is largely unknown. A later altar relief from the Temple of Castor and Pollux in the Roman Forum may depict her. A Roman festival was held in her honor on January 11, when she was given sacrifices and honored by the fontani (the men who maintained the fountains and aqueducts of Rome).

Honours
