world. The nearest approach, and that is a remote one, is found in archaic Indian carvings. Everywhere there are woven feathers and serpents twine in and out. Many Maya inscriptions resemble a certain sort of elaborate drawing made by lunatics in European asylums, more than any other old-world work. It is as if the Maya mind had developed upon a different line from the old-world mind, had a different twist to its ideas, was not, by old-world standards, a rational mind at all.
This linking of these aberrant American civilizations to the idea of a general mental aberration finds support in their extraordinary obsession by the shedding of human blood. The Mexican civilization in particular ran blood; it offered thousands of human victims yearly. The cutting open of living victims, the tearing out of the still beating heart, was an act that dominated the minds and lives of these strange priesthoods. The public life, the national festivities all turned on this fantastically horrible act.
