of mythology "embodied" in the star. "Hesperus is Phosphorus" 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. Latin literature 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.
