It was named after the one-eyed Cyclops

had only shown that binocular disparity was necessary for stereopsis. Ironically, the Cyclops would not have been able to see a cyclopean stimulus, because having only one eye, he would not have been able to perceive binocular depth cues such as binocular disparity.
