(10139) Ronsard Main-belt Asteroid
Discovered on 19 September 1993 by E. W. Elst at Caussols.
Named in memory of Pierre de Ronsard (1524-1585), the most important member of the group of poets known as “La Pléiade”. Much inspired by Greek and Roman poetry, following Horatius' example he composed the Odes (1550). He is most remembered for his Amours de Marie and the Sonnets pour Hélène. A reflection on the brevity of youth and beauty, his Mignonne, allons voir si la rose has been set to music half a dozen times since the sixteenth century.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
