Echo

In Greek mythology, a nymph of whom several stories are told. Either she was beloved by Pan, and was torn to pieces, only her voice surviving; or she was punished by Hera so that she could only repeat the last words of another speaker. She loved Narcissus, who rejected her, so that she wasted away to a voice.
