URA'NIA (Οὐρανία) 1. One of the Muses, a daughter of Zeus by Mnemosyne. (Hes. Theog. 78 ; Ov. Fast. v. 55.) The ancient bard Linus is called her son by Apollo (Hygin. Fab. 161), and Hymenaeus also is said to have been a son of Urania. (Catull. lxi. 2.) She was regarded, as her name indicates, as the Muse of Astronomy, and was represented with a celestial globe to which she points with a little staff. (Hirt, Mythol. Bilderb. p. 210.)
