|Look up Phosphorus in Wiktionary, the free dictionary.|
Phosphorus (Ancient Greek: Φωσφόρος, romanized: 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 Heosphorus (Ancient Greek: Ἑωσφόρος, romanized: Heōsphoros), meaning "the dawn-bringer". The form Eosphorus is sometimes met in English. As an adjective, the Greek word φωσφόρος is applied in the sense of "light-bringing" to (for instance): the dawn, the god Dionysus, pine torches, the day; and in the sense of "torch-bearing" as an epithet of several gods and goddesses, especially of Hecate but also of Artemis/Diana and Hephaestus. Objectively, Venus is the "light bringer" in the northern hemisphere, as she appears most brightly in the sky in December (optical illusion due to days being shorter there at that time); the most regular appearance of the planet signalled a beginning of "rebirth" phase where the days would get longer and winter would end.
The morning star is an appearance of the planet Venus, an inferior planet, meaning that its orbit lies between that of 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.
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.
While at an early stage the Morning Star (called Phosphorus and other names) and the Evening Star (referred to by names such as Hesperus) were thought of as two celestial objects, the Greeks accepted that the two were the same, but they seem to have continued to treat the two mythological entities as distinct. Halbertal and Margalit interpret this as indicating that they did not identify the star with the god or gods of mythology "embodied" in the star.
"Hesperus is Phosphorus"Edit
In the philosophy of language, "Hesperus is Phosphorus" is a famous sentence in relation to the semantics of proper names. Gottlob Frege used the terms "the evening star" (der Abendstern) and "the morning star" (der Morgenstern) to illustrate his distinction between sense and reference, and subsequent philosophers changed the example to "Hesperus is Phosphorus" so that it utilized proper names. Saul Kripke used the sentence to posit that the knowledge of something necessary — in this case the identity of Hesperus and Phosphorus — could be discoverable rather than known a priori.
The Latin word corresponding to Greek "Phosphorus" is "Lucifer". It is used in its astronomical sense both in prose and poetry. Poets sometimes personify the star, placing it in a mythological context.

… vigil nitido patefecit ab ortu

atria: diffugiunt stellae, quarum agmina cogit
Lucifer et caeli statione novissimus exit
Aurora, awake in the glowing east, opens wide her bright doors, and her rose-filled courts. The stars, whose ranks are shepherded by Lucifer the morning star, vanish, and he, last of all, leaves his station in the sky – Metamorphoses 2.114–115; A. S. Kline's Version
Et iam Mygdoniis elata cubilibus alto
impulerat caelo gelidas Aurora tenebras,
rorantes excussa comas multumque sequenti
sole rubens; illi roseus per nubila seras
aduertit flammas alienumque aethera tardo
Lucifer exit equo, donec pater igneus orbem
impleat atque ipsi radios uetet esse sorori
(And now Aurora rising from her Mygdonian couch had driven the cold darkness on from high in the heavens, shaking out her dewy hair, her face blushing red at the pursuing sun – from him roseate Lucifer averts his fires lingering in the clouds and with reluctant horse leaves the heavens no longer his, until the blazing father make full his orb and forbid even his sister her beams) Statius, Thebaid 2, 134–150; Translated by A.
