Selēnē in Later Traditions
The Romans identified Selḗnē with Luna, though as with Hēlios/Sol, the Greek goddess was increasingly absorbed by Artemis-Diana in later periods — the triple lunar goddess of Neoplatonic and magical thought fuses all three. In Hellenistic and Roman Egypt, Selḗnē was syncretized with Isis, who wears the lunar disk between the horns of a cow; the aretalogy of Isis at Maroneia explicitly calls her 'the one who ascends in the gold-wreathed hour'. Neoplatonists made the moon the boundary between the material and immaterial realms, and Selḗnē the mediator between Hēlios and the earth. The scientific afterlife of her name is everywhere: selenography (mapping the moon), selenology, and the element selenium — the Greeks' moon-goddess now names a column of the periodic table.
