3360 Syrinx           Discovered 1981 Nov. 4 by E. F. Helin and R. S. Dunbar at Palomar.
In 1918 the Danish composer Carl Nielsen (1865-1931) composed the tone poem Pan and Syrinx, based on a story in Ovid's Metamorphoses. Syrinx was a river nymph who was pursued by Pan. The gods, taking pity on her, transformed her into a collection of reeds. The name was suggested by J. Meeus.
