It may seem strange that in Roman times the British god Nodens, famous for his healing shrine, was associated with Mars, a god more likely to do damage than to cure it. However, other Celtic “Mars” gods such as Lenus and Ocelus were healers, and not just to soldiers or men, but women and children.
This post covers the darker side of Helios‘ family. These include Circe, Pasiphaë, and his granddaughters Medea and Hecate. Unlike his brighter descendants, who were mostly the children of Klymene, these were the children of Perseis, an Oceanid nymph. (Her name comes from the word persô, meaning to destroy, slay, ravish, or sack with fire, so perhaps her dangerous offspring shouldn’t be a surprise.)
Asteria is another Greek star-goddess, but of a rather different type. She was associated with oracles of darkness, such as prophetic dreams, astrology, falling stars, and necromancy. (Her daughter Hecate, the witch’s goddess, would follow in her footsteps.) She was sometimes blended with the night-goddess Nyx, an alternate mother for Hecate.
Like Belisama, Solimara and Sulis, Sirona’s cult centers on healing water, whether hot springs, baths or wells. Her name, however, means something like “Great Star”, which would make her a star-goddess, rather than a solar one. She is linked to several gods, including the Roman sun-god Apollo, as well as the gods Grannus and Atesmertius.
