This set came from the wall murals of Atetelco in Teotihuacan |
At the University of Teotihuacan, DF. one can study astronomy and probably a form of physics.
This lesson .appears to have three aspects. Finding the stars in the sky, then measuring them on the ground. The second and third (B and C) are similar to the layout on the ground at Beijing Observatory, China. However, I believe their version was only to measure the daylight hours during the seasons.
These two have more of an affinity for the version in Japur Observatory in India. The double pool at one end with measuring markings. Were these lessons for the pre-comet fall-out, or was it for the post-comet event displayed on the Aztec Calendar Stone. So many polities make a small lesson plan into a greater lesson to learn.
The professors at Teotihuacan are displayed on the walls of other buildings. Their speech scrolls tell the students what is to be studied in their classes.
Astro-Physics was just one of many classes given in this university system.Not only finding the stars in the sky, but also measuring them on land with specific measuring pools and long markess sumilar to those found at the Observatory at Jaipur, India..
Lessons such as Astronomy, not only to locate stars,
but also to measure them to the ground in pools of water
similar to Jaipur, India. Their experts were also designated to teach.

On the other hand, without clean water, people living in a water-based city would have a very serious problem. Night soils and trash were collected daily; aqueducts were built to bring fresh water into the area. It was essential that the water for lake cities be kept clean and flowing normally. No hidden standing puddles for mosquitoes. Agents were trained to test the water and make sure it was potable.
