Echoes-2

Echo was a mountain nymph that told Hera stories to distract her while Zeus consorted with the other nymphs. When Hera found out, she punished Echo by making her only able to repeat what other people say.These two words relate, because Echo was only able to repeat what other people said, and an echo is a sound that is repeated. As Helen walked down the hall she could hear the echo of her own footsteps.
In Greek mythology, Echo (Greek: Ἠχώ, Ēchō/Hēchō) was an Oread (a mountain nymph) who loved her own voice. Zeus loved consorting with beautiful nymphs and visited them on Earth often. Eventually, Zeus's wife, Hera, became suspicious, and came from Mt. Olympus in an attempt to catch Zeus with the nymphs.
Zeus, the King of the Olympians, was known for his many love affairs. Sometimes the young and beautiful Nymph Echo would distract and amuse his wife Hera with long and entertaining stories, while Zeus took advantage of the moment to ravish the other mountain nymphs. When Hera discovered the trickery she punished the talkative Echo by taking away her voice, except in foolish repetition of another's shouted words. Thus, all Echo could do was repeat the voice of another.
Echo fell in love with a vain youth named Narcissus, who was the son of the blue Nymph Leirope of Thespia. The river god Cephisus had once encircled Leirope with the windings of his streams, and thus trapping her, had seduced the nymph. Concerned about the baby's welfare, Leirope went to consult the prophet Teiresias regarding her son's future. Teiresias told the nymph that Narcissus "would live to a ripe old age, as long as he never knew himself."
One day when Narcissus was out hunting stags, Echo stealthily followed the handsome youth through the woods, longing to address him but unable to speak first. When Narcissus finally heard footsteps and shouted "Who's there?", Echo answered "Who's there?" And so it went, until finally Echo showed herself and rushed to embrace the lovely youth. He pulled away from the nymph and vainly told her to leave him alone. Narcissus left Echo heartbroken, and she spent the rest of her life in lonely glens pining away for the love she never knew until only her voice remained. However, in other versions Echo cries until she is stone and an invisible Echo (probably her ghost/spirit) haunts the Earth.
