The myth of the unicorn continues to delight and confound. The Ancient Greeks, like Father Palacios, believed in it as natural history, rather than mythology; it makes an appearance in ancient Chinese mythology as the quilin; Marco Polo described them as 'very ugly brutes,' and it was thought pretty young virgins could be used to entrap them. The unicorn paintings in the caves at Lago Posadas that Father Palacios describes have been dated to approximately 3850 years ago - although they are far more faded than the rock paintings in the nearby Cueva de las Manos.
