Syrinx

Syrinx in Greek mythology, was a daughter of the river-god Lado, who, when pursued on account of her beauty by Pan, prayed to her father for relief, and was changed into a reed. Pan cut some stalks from it, joined them together with wax, and used it, in the form known to us as Pan's pipe, in remembrance of her (Ovid, Metam. 1, 690).
