(14403) de Machault Main-belt Asteroid
Discovered on 8 April 1991 by E. W. Elst at La Silla.
Guillaume de Machault (c.1300–1377) was a medieval poet and one of the last poet-musicians. He belonged to the ars nova musical movement and perfected the secular song forms, rondeau and balade. His masterpiece, Le voir dit, includes deliberate inconsistencies that force a reader to question the truthfulness of the story.Naming citation (WGSBN Bull. 3, #14, 7), IAU / Minor Planet Center, via NASA/JPL
