Hesperus (Greek Hesperos) is the personification of the "evening star", the planet Venus in the evening. His name is sometimes conflated with the names for his brother the personification of the planet as the "morning star" Eosphorus (Greek polytonic|Ἐωσφόρος, "bearer of dawn") or
Phosphorus (Ancient Greek: polytonic|Φωσφόρος, "bearer of light", often translated as "Lucifer " in Latin), since they are all personifications of the same planet Venus. "Heosphoros" in the GreekLXX Septuagint and "Lucifer" inJerome 's LatinVulgate were used to translate the Hebrew "Helel" (Venus as the brilliant, bright or shining one), "son of Shahar (Dawn)" in the Hebrew version ofIsaiah 14:12.When named thus by the early Greeks, it was thought that Eosphorus (Venus in the morning) and Hesperos (Venus in the evening) were two different celestial objects. The Greeks later accepted the Babylonian view that the two were the same, and the Babylonian identification of the planets with the Great Gods, and dedicated the "wandering star" (
planet ) toAphrodite (Roman Venus), as the equivalent ofIshtar .Eosphorus/Hesperus was said to be the father of Ceyx [Hyg. Fab. 65] and
Daedalion . [Ovid. "Metamorphoses". Book XI, 295.] In some sources, he is also said to be the father of theHesperides . [Servius. ad Aen. 4,484.]"Hesperus is Phosphorus"
"Hesperus is Phosphorus" is a famous sentence in the
philosophy of language (see, e.g.,proper name ).Gottlob Frege used the terms "Hesperus" and "Phosphorus" to illustrate his distinction betweensense and reference .Saul Kripke used the sentence to demonstrate that the knowledge of something necessary (in this case the identity of Hesperus and Phosphorus) could be discoverable rather than known a priori.ee also
