One day Narcissus was walking in the woods. Echo, a beautiful mountain nymph (who had been cursed so she could only speak the last words spoken to her) saw him and fell in love. But when Echo showed herself and told him of her love, Narcissus told her to leave him alone.
Later that summer, when Narcissus was thirsty after hunting, he went to drink from a pool of water. Nemesis the Goddess of revenge heard of how Narcissus had rejected Echo, so she cursed Narcissus to fall in love with the person he saw in the pool. He did not realise it was his own reflection. Unable to leave the allure of his image, Narcissus eventually realized that his love could not be reciprocated.
Lovesick and heartbroken Narcissus gradually faded away, eventually turning into a gold and white flower (daffodil). Echo was so heartbroken that Narcissus had rejected her, that she spent the rest of her life in lonely glens, until she also faded away. Only an echo sound remains of her.
Daffodil (Narcissus pseudonarcissus) means regard.
