Polyhymnia. Polyhymnia, also spelt Polymnia was in Greek mythology the Muse of sacred poetry, sacred hymn, dance, and eloquence as well as agriculture and pantomime. Her name comes from the Greek words poly meaning many and hymnos, which means praise. She is depicted as very serious, pensive and meditative, and often holding a finger to her mouth, dressed in a long cloak and veil and resting her elbow on a pillar. Polyhymnia is also sometimes credited as being the Muse of geometry and meditation. In Bibliotheca historica, Diodorus Siculus wrote, Polyhymnia, because by her great praises she brings distinction to writers whose works have won for them immortal fame. She appears in Dante's Divine Comedy: Paradiso. Canto XXIII, line 56, and is referenced in modern works of fiction. Polyhymnia was also described as the mother of Triptolemus by Cheimarrhoos, son of Ares, and of the musician Orpheus by Apollo. In astronomy, there are nine asteroids named after the Muses. The one named after Polyhymnia is a main belt asteroid discovered by Jean Chacornac, a French astronomer, in 1854. On Mount Parnassus, there was a spring that was sacred to Polyhymnia and the other Muses. It was said to flow between two big rocks above Delphi, then down into a large square basin. The water was used by the Pythia, who were priests and priestesses, for oracular purposes including divination.
