"There are various stories of the Greek nymph Echo. In one story, Hera was angry at Echo for conspiring with other nymphs who, unlike Echo, wanted to be with Hera's husband Zeus. As punishment, Hera made Echo no longer able to say words of her own, but only to echo those spoken by others. Another story is that she fell in love with the beautiful youth Narcissus who spurned her and caused her to shrivel up into nothing more than an echo. In other versions of the Narcissus story, Echo was alive and mourned the death of Narcissus.
Longus, Ovid, and Pausanias are among those who wrote about Echo."1
