Chin, a small child or dwarf god, introduced homoerotic relationships to the Mayan nobles. The nobles obtained youths of the lower classes to be the lovers of the noble's sons. Such unions were considered legal marriages under Mayan law, and any attempt on the honor of the younger partner was punishable as adultery. About Chin's mythological role, nothing else is known.
The picture does not represent the god Chin - we found no images of this god - but just a sitting mayan man
