Narcissus was a strong and beautiful boy of Greek mythology. He is also known for his cruel disposition; he rejected the love of the youths, boy and girl, who adored him. His final act of rejection led to him being cursed by the deity of retribution, Nemesis. He fell in love with his own reflection in the water, which inadvertently led to his death. Accounts vary on the circumstances that brought Narcissus to his watery death - and even the cause of his death differs; he either drowned himself trying to embrace the image, starved to death, or killed himself for being unable to accept this love. Either way, a flower grew from the spot he died, which was named the "narcissus".
