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.
Function:
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.
