"he is a Narcissus"

In the tale told by Ovid, a nymph called Echo falls in love with the vain youth Narcissus. He spurns her, more interested in his own good looks. Echo is heartbroken and spends the rest of her life pining for him until only her voice remains. Meanwhile, Narcissus is punished by the Gods. Taking a drink from a pool in a forest, he falls in love with his own reflection. Of course, nothing can ever come of this, so Narcissus dies in despair. His soul is sent to hell and the narcissus flower grows in his place, continuing to gaze into the water.
