Tikal: Twin Pyramid complex

Twin Pyramid Complex Q, South Building [January 5, 2004]

"The use of the number nine in twin-pyramid group activities is immediately suggested by the south building which always had nine doorways. One can imagine the appearance of the nine "Lords of the Night" or of priests carrying nine items for sacrifice, and so forth."
