Phosphorus (morning star)
Summary
Phosphorus (Phōsphoros) is one of the Astra Planeta, specifically the god of the planet Venus in its appearance as the Morning Star. Another Greek name for the Morning Star is "Eosphorus" (Heōsphoros), which means "dawn-bringer". The term "eosphorus" is sometimes met in English. As an adjective, the word "phosphorus" is applied in the sense of "light-bringing" (for instance, the dawn, the god Dionysus, pine torches and the day) and "torch-bearing" as an epithet of several gods and goddesses, especially of Hecate but also of Artemis/Diana and Hephaestus. Seasonally, Venus is the "light bringer" in the northern hemisphere, appearing most brightly in December (an optical illusion due to shorter days), signalling the "rebirth" of longer days as winter wanes.
The morning star is an appearance of the planet Venus, an inferior planet, meaning that its orbit lies between the Earth and the Sun. Depending on the orbital locations of both Venus and Earth, it can be seen in the eastern morning sky for an hour or so before the Sun rises and dims it, or (as the evening star) in the western evening sky for an hour or so after the Sun sets, when Venus itself then sets.
Venus is the brightest object in the sky after the Sun and the Moon, outshining the planets Jupiter and Saturn but, while these rise high in the sky, Venus never does. This may lie behind myths about deities associated with the morning star proudly striving for the highest place among the gods and being cast down.
In Greek mythology, Hesiod calls Phosphorus a son of Astraeus and Eos, but other say of Cephalus and Eos, or of Atlas.
The Latin poet Ovid, speaking of Phosphorus and Hesperus (the Evening Star, the evening appearance of the planet Venus) as identical, makes him the father of Daedalion. Ovid also makes him the father of Ceyx, while the Latin grammarian Servius makes him the father of the Hesperides or of Hesperis.
