There used to be an ancient civilization centuries ago near Mexico City. This Teotihuacan civilization was 40 kilometers northeast of Mexico City, but most of its area went into hiding. Now a new study has found that the traces of Teyotivakan are visible in the roads and structures built here about 1500 years after this civilization. Researchers found that in ancient society, engineering work was done unmatched. On the basis of astronomical knowledge, these people used to build the paths of rivers. They used to transport from mud to rocks to build the city.
work on the ground
“We live not in history but in traces of its actions,” said University of California archaeologist Nawa Sugiyama. The consequences of those actions are still visible on the ground in a city like Teyotivakan. The LIDAR map has shown a picture of these ancient features that are rapidly disappearing and facing the danger of disappearing. In this way we can preserve them.
LIDAR TECHNOLOGY HELP
According to the Daily Express report, between 100 BCE and 550 CE Teyotivakan was one of the largest cities in the ancient world. It was spread over an area of 21 square kilometers and had many pyramids, plazas, commercial and residential buildings. Some structures can still be seen today. However, most have disappeared. Traces of missing structures can also be seen with the help of LIDAR technology. With its help, underground structures can be seen by reflecting laser light.
Researchers compared today’s Teyotiwakan Valley and ancient civilization with the help of LIDAR, ground survey and previously collected data. They found that 65% of urban areas were built at the same angle as in ancient civilizations. Today’s structures are being built on the traces of the ancient walls. In the Teyotiwakan civilization, rivers were also diverted and canals were built. The research found that 16.9 km of today’s waterways have their origins in the ancient Teyotivakan landscape.
many structures destroyed
The environmental, cultural and academic composition of the Teyotiwakan Valley can explain the potential for humans to transform the land, the paper said. It has been estimated in the research that about 3,72,056 square meters of artificial ground was laid in 300 years. 298 features and 5,795 human-made structures were discovered that were not previously recorded. It was also discovered that over 200 features were destroyed in mining.
