Aricia was, according to Greek mythology, niece of Aegeus. She was the last one of the Pallantides and married Hippolytus, or Virbius, after he was brought back to life on the request of Artemis.

Aricia was an ancient town

Now Riccia; an ancient town of Latium at the foot of the Alban Mount, on the Appian Way, sixteen miles from Rome. It was subdued by the Romans, with the other Latin towns, in B.C. 338, and received the Roman franchise. In its neighbourhood were the celebrated grove and temple of Diana Aricina, on the borders of the Lacus Nemorensis. Diana was worshipped here with barbarous customs; her priest, called Rex Nemorensis, was always a runaway slave, who obtained his office by killing his predecessor in single combat. (Harry Thurston Peck, Harpers Dictionary of Classical Antiquities (1898))

Pausanias 2.27.4

--Apart from the others is an old slab, which declares that Hippolytus dedicated twenty horses to the god. The Aricians tell a tale that agrees with the inscription on this slab, that when Hippolytus was killed, owing to the curses of Theseus, Asclepius raised him from the dead. On coming to life again he refused to forgive his father rejecting his prayers, he went to the Aricians in Italy. There he became king and devoted a precinct to Artemis, where down to my time the prize for the victor in single combat was the priesthood of the goddess. The contest was open to no freeman, but only to slaves who had run away from their masters.

Aricia medon

Aricia was a Celtic Ricon who betrayed Caradoc, her former lover, to the Romans after he married someone else. Beautiful and wicked, she was rumored to be a dark witch. She lived in Camulodonon (Colchester) for a while and went on to rule Brigantia (the North). She supported "Romanization" and she was a bit older than Boudicca.
