Ηχω
A Nymph of the trees and springs; some of the legends surrounding her provide explanations of the phenomenon of echoes. In one account Echo was vainly loved by Pan and loved a satyr instead, who shunned her; in revenge, Pan sent some shepherds mad, who tore her to pieces. In another account Echo loved Narcissus unrequitedly and pined away; when she died her voice alone remained - this repeated the last syllables of spoken words.
