Echo (583 words)
In Greek mythology, Echo (Greek Ηχω) was an Oread who had the job of talking incessantly to Hera, the Queen of the Gods, so that her husband, Zeus, wouldn't get caught in his numerous affairs.
Echo was embarrassed to talk to him, because she couldn't, but she had an urge to see him.
Alternatively, Echo was a nymph who was a great singer and dancer and scorned the love of any man. This angered Pan, a lecherous god, and he instructed his followers to kill her.
