Nar·cis·sus, \när-ˈsis-əs\ Greek mythological character. Narcissus was a youth of renowned beauty. Transfixed by his own beauty, he contemplated his reflection in a pool of water. The more he looked, the more he liked what he saw. Held captive by his self-love, he never strayed from the pool, but gradually wasted away and died. The gods then transformed him into the flower which is now called narcissus after him.
