Bk III:339-358 Echo sees Narcissus.
Famous throughout all the Aoniancities, Tiresias gave faultless answers to people who consulted him. Dusky Liriope, the Naiad, was the first to test the truth and the accuracy of his words, whom once the river-god Cephisus clasped in his winding streams, and took by force under the waves. This loveliest of nymphs gave birth at full term to a child whom, even then, one could fall in love with, called Narcissus. Being consulted as to whether the child would live a long life, to a ripe old age, the seer with prophetic vision replied, "If he does not discover himself."
For a long time the augur's pronouncement appeared empty words. But in the end it proved true: the outcome, and the cause of his death, and the strangeness of his passion. One year the son of Cephisus had reached sixteen and might seem both boy and youth. Many youths, and many young girls desired him. But there was such intense pride in that delicate form that none of the youths or young girls affected him. One day the nymph Echo saw him, driving frightened deer into his nets, she of the echoing voice, who cannot be silent when others have spoken, nor learn how to speak first herself.
