In Greek tradition, Phosporus was the personification of the evening star (Venus). Heosphoros in Homer and Hesiod denotes the morning star. (Heosphoros appears in the Septuagint to translate a word in Isaiah 14:12, that Jerome translates "Lucifer" in the 4th century Vulgate. See entry at Lucifer.)

Modern Wiccan devotés and demonologists make Jerome's Lucifer the father of Aradia by Diana. Though they refer to a "Roman tradition," no such written myth exists. He was also the father of Ceyx.

Also spelled Phosphorus.
