Stone slab, bas-relief carvings of Monte Alban, Mexico, dating to c 100 BC-100 AD, that flank the earliest flat-topped. They depict nude male figures, some with mutilated or elaborately emphasized sexual organs, in unnatural dancing or possible swimming poses. Certain elements of the iconography, such as thick lips and downturned mouths, indicate an Olmec origin. Associated hieroglyphs and calendar dates support this theory. The term means "dancer" in Spanish. These are usually life-sized and have been found at San Jose Mogote and Monte Alban in Oaxaca.
