But Diana did not reign alone in her grove at Nemi. Two lesser
divinities shared her forest sanctuary. One was Egeria, the nymph of
the clear water which, bubbling from the basaltic rocks, used to
fall in graceful cascades into the lake at the place called Le Mole,
because here were established the mills of the modern village of
Nemi. The purling of the stream as it ran over the pebbles is
mentioned by Ovid, who tells us that he had often drunk of its
water. Women with child used to sacrifice to Egeria, because she was
believed, like Diana, to be able to grant them an easy delivery.
Tradition ran that the nymph had been the wife or mistress of the
wise king Numa, that he had consorted with her in the secrecy of the
sacred grove, and that the laws which he gave the Romans had been
inspired by communion with her divinity. Plutarch compares the
legend with other tales of the loves of goddesses for mortal men,
such as the love of Cybele and the Moon for the fair youths Attis
and Endymion. According to some, the trysting-place of the lovers
was not in the woods of Nemi but in a grove outside the dripping
Porta Capena at Rome, where another sacred spring of Egeria gushed
from a dark cavern. Every day the Roman Vestals fetched water from
this spring to wash the temple of Vesta, carrying it in earthenware
pitchers on their heads. In Juvenal's time the natural rock had been
encased in marble, and the hallowed spot was profaned by gangs of
poor Jews, who were suffered to squat, like gypsies, in the grove.
We may suppose that the spring which fell into the lake of Nemi was
the true original Egeria, and that when the first settlers moved
down from the Alban hills to the banks of the Tiber they brought the
nymph with them and found a new home for her in a grove outside the
gates. The remains of baths which have been discovered within the
sacred precinct, together with many terra-cotta models of various
