No. 2: Temple of the Sun, Palenque, Chiapas, Mexico

Classic Maya civilization city state.  This dedication temple built around 683A.D.  Infrared film with color added.

I have many other detail photographs of this site from twenty years back.

When the first rays of light beam during the Sun's Zenith (Solstice

Equinox cycles) into the Temple of the Sun meeting on an angle corner of a pillar inside, the time to plant, reap, sow is foretold. 

The wonder of Mayan astronomy.
