A new study shows that billions of lasers fired from helicopters flying over the Amazon rainforest in Brazil detected a vast network of long abandoned circular and rectangular villages from 1300 to 1700. It became clear in.
The round villages all had a very similar layout, with elongated mounds surrounding the central square like a clock mark.
“These latter elongated mounds look like the rays of the sun when viewed from above. This is the common name for” sowa, “which means” sun “in Portuguese,” the researchers wrote in a study. I am.

This discovery is part of a new archaeological focus on the pre-Columbian Amazon. Within the last two decades, researchers have learned that the southern edge of the rainforest is home to a vast variety of soil sculpture cultures that designed landscapes before the arrival of Europeans. Within the last decade, scientists have discovered the remains of so-called “mound villages,” which are circular or rectangular in shape and connected by a road network.
However, archaeologists had not yet searched for the village of Mound in the state of Acre, Brazil, so an international group of researchers teamed up to explore the area with riders, light detection and ranging. In this technique, billions of lasers fired overhead (in this case a helicopter) penetrate the rainforest canopy and map the landscape below.
A lidar survey combined with satellite data revealed 25 circular mound villages and 11 rectangular mound villages. The team added that another 15 mound villages were so poorly preserved that they could not be classified as either circular or rectangular.
The average diameter of the circular mound village was 282 feet (86 meters), while the average length of the rectangular village was 148 feet (45 meters). Further analysis of the “Sun” village revealed that the roads were carefully planned. Each circular mound village has two wide and deep (up to 20 feet (6 m) wide) “main roads”, a high embankment and a small “minor road” leading to a nearby stream. did.
Researchers have found that most villages are close to each other, only about 3 miles (4.4 km) apart. Researchers said major roads often connected one village to another, forming a vast community network in the rainforest.
The unique and consistent way indigenous people placed these villages suggests that they had a particular social model for how they organized their communities, the researchers said. They even said that this composition was intended to represent the universe.
But complex road systems are “not surprising to Amazon archaeologists,” the researchers write in a study. “Early historical accounts prove the ubiquity of the road network throughout the Amazon. They have been mentioned since the 16th century account. [the Spanish Dominican missionary] Monk Gaspar de Carvajal observes the wide road leading from the riverside village to the inside. Then, in the 18th century, Colonel Antonio Pires de Campos said, “I described the huge population of the area, where the village was connected by straight, wide roads. It was always kept clean.”
Little is known about the culture practiced by the people of these mound villages. However, according to preliminary research, the pottery of this culture was “crude” than the pottery of the previous culture known as geoglyphs, who lived in the area from 400 BC to 950 AD.
