Juturna

In Roman mythology, Juturna was the goddess of fountains, wells and springs. She was a sister of Turnus and supported him against Aeneas. She was also the mother of Fontus by her husband, Janus.

Jupiter turned her into a nymph and gave her a sacred well in Lavinium, Latium, as well as another one near the temple to Vesta in the Forum Romanum. The second well was called Lacus Juturnae.

Juturna had an affair with Jupiter but the secret was betrayed by a nymph named Lara, whom Jupiter struck with muteness as punishment.
