Chief among the nymphs was Carmenta, or Carmentis, who had a spring and a grove outside the Porta Capena at Rome where the Vestal Virgins drew water for their rites. Her festival, the Carmentalia (January 11 and 15), shared one day, called the Juturnalia (January 11) with Juturna, a nymph of a fountain in Latium that was famous for its healing qualities. Egeria, another of the nymphs, instructed Numa Pompilius on the forms of worship which he introduced. The grove where his interviews with the goddess took place was dedicated to the Camenae. The nymphs were honored with Volcanus, the god of fire, during the Vulcanalia (August 23). It is not unreasonable to suspect that they were honored along with Fons, the god of fountains, during the Fontinalia (October 13).
