Greek mythologyGreek mythology is the body of myths originally told by the ancient Greeks, and a genre of ancient Greek folklore, today absorbed alongside Roman mythology into the broader designation of classical mythology. These stories concern the ancient Greek religion's view of the origin and nature of the world; the lives and activities of deities, heroes, and mythological creatures; and the origins and significance of the ancient Greeks' cult and ritual practices.
AurvandillAurvandill (Old Norse) is a figure in Germanic mythology. In Norse mythology, the god Thor tosses Aurvandill's toe – which had frozen while the thunder god was carrying him in a basket across the Élivágar rivers – into the sky to form a star called Aurvandils-tá ('Aurvandill's toe'). In wider medieval Germanic-speaking cultures, he was known as Ēarendel in Old English, Aurendil in Old High German, Auriwandalo in Lombardic, and possibly as auzandil in Gothic.
HesperusIn Greek mythology, Hesperus (ˈhɛspərəs; Hésperos) is the Evening Star, the planet Venus in the evening. He is one of the Astra Planeta. A son of the dawn goddess Eos (Roman Aurora), he is the half-brother of her other son, Phosphorus (also called Eosphorus; the "Morning Star"). Hesperus' Roman equivalent is Vesper (cf. "evening", "supper", "evening star", "west"). By one account, Hesperus' father was Cephalus, a mortal, while Phosphorus was the star god Astraios.
Sense and referenceIn the philosophy of language, the distinction between sense and reference was an idea of the German philosopher and mathematician Gottlob Frege in 1892 (in his paper "On Sense and Reference"; German: "Über Sinn und Bedeutung"), reflecting the two ways he believed a singular term may have meaning. The reference (or "referent"; Bedeutung) of a proper name is the object it means or indicates (bedeuten), whereas its sense (Sinn) is what the name expresses. The reference of a sentence is its truth value, whereas its sense is the thought that it expresses.
