The Greeks believed that true beauty (as opposed to mere prettiness) was the offspring of these two opposing tendencies, which they personified in Apollo and Dionysus, their two gods of art. Great art is born when Apollonian form and Dionysian ecstasy are held in balance, when our dreams of order and abandon come together. One tendency uninformed by the other can bring forth only coldness or chaos-the stiffness of a Triumph tulip, the slackness of a wild rose.
