The title of the myth is "Echo and Narcissus" by Roger Lancelyn Green
"And Aphrodite, the goddess of love, heard her and was kind to her, for she had been a true lover. Quietly and painlessly, Echo pined away and died" (Lancelyn Green 4).
The main theme of "Echo and Narcissus" is that when in love, one must suffer.
The myth "Echo and Narcissus" starts with Hera, Zeus' wife, cursing Echo to only repeat what she hears because Echo would talk too much. Then, a young man named Narcissus wanders into the woods and Echo falls in love with him. Narcissus calls out for help and when Echo tries to help him, he flings her off of him and she pines away and dies. Aphrodite takes this personally seeing how Echo was truly in love and she curses Narcissus to only fall in love with himself. Some time later, Narcissus comes across a reflective pond and falls in love with his reflection without realizing it. He persists on being with his "true love" and soon dies loving in vain.
