In Greek mythology, Echo was a nymph whom Hera punished by making it impossible for her to speak first or to be silent whenever anyone else was speaking. She fell in love with Narcissus, for whom she pined until only her voice was lefthence, the derivation of the word 'echo.' Apollo punished Narcissus for spurning Echo by having him fall in love with himself when he saw his reflection in the water of a fountain.
