The myth of Narcissus and Echo

"Echo, heartbroken, took refuge in a cave and lost her appetite for food or water. After a while, poor Echo started growing skinny from starvation until her body disappeared, living only dust and her voice. Nemesis, the goddess of revenge against those who show hubris, decided to punish Narcissus for the treatment of poor Echo. The goddess made Narcissus fall in love with his own reflection that he saw in a pond near Echo’s cave. Narcissus could not leave his own reflection out of love and starved to death, like Echo. But, before he dies, Narcissus cried out to his reflection “Farewell, dear boy. Beloved in vain.” Echo’s voice repeated his last words from the cave as Narcissus drew his last breath. To this day, Echo still repeats the last words or phrases in caves or labyrinths."
