50 kilometers northeast of Mexico City, the ancient city of Teotihuacan. I stood in the cool breeze of the castle grounds, looking north and looking at the Pyramids of the Sun and the Moon (Pyramids of the Sun and the Moon) standing in the misty morning light.

In the wilderness covered with green shrubs and surrounded by distant mountains, an axis suddenly appeared - the locals called it the "Street of the Dead" - with ruins scattered on both sides; these two magnificent

The pyramid stands among them, like two musicians in a symphony orchestra, participating in playing a piece of music.

The location of the castle is close to this broad and straight axis, which is more than 4 kilometers long.

The Pyramid of the Moon is located at the northern end of the axis, while the Pyramid of the Sun is slightly offset from the axis and is located on the east side.

Facing such an ancient city built on geometric principles, most tourists would expect that the axis of the city stretches along the north-south or east-west direction. But to everyone's surprise, the architect who originally designed Teotihuacan,

However, this "Road of the Dead" was deliberately tilted slightly, pointing to a position of 15 degrees and 30 minutes east of north.

Why did you choose such a weird direction in the first place?

Experts have proposed several explanations, but none are convincing enough.

More and more scholars believe that this layout may be related to celestial phenomena.

For example, one of the scholars pointed out that the "Road of the Dead" goes directly to "the position of the seven stars of Taurus (the Pieiades) in the sky at the time of its construction"③.

Professor Gerald Hawkins believes that the axis in the city may represent the "Strins-Taurus seven-star axis".

④Stansbury Hagar (Stansbury Hagar) of the Department of Ethnography at the Brooklyn Institute of the Arts and Sciences believes that the "Road of the Dead" may represent the Milky Way in the sky⑤ Hagar further pointed out:

Along both sides of this axis, there are many pyramids, mounds and other buildings arranged like fixed satellites, representing certain planets and other stars in the sky.

According to his theory, the original architects designed Teotihuacan as "a map of the heavens": "They copied the imaginary heaven - the place where the gods and the dead live - on the ground."⑥

In the 1960s and 1970s, Hugh Harleston, Jr., an American engineer living in Mexico, carried out comprehensive surveys based on mathematical principles in the ancient city of Huacan in Teo to test Hugh's theory on the spot.

In October 1974, Harlesden reported his findings to the International Congress of Americanists.

His papers are full of bold and original insights.

One of the most intriguing finds involves the fortress of the ancient city and the Temple of Quetzalcoatl, which lies to the east of the vast, square enclosure.

Scholarly circles recognize this temple as one of the best-preserved monuments in Mesoamerica.

It survives intact because this prehistoric building was partially buried under another later mound that stood in front of it (slightly to the west).

Archaeologists excavated the mound and discovered a beautiful six-level pyramid buried underneath.

At this moment, I am standing in front of it, admiring this ancient temple that is 72 feet high and has a foundation that is 82,000 square feet wide.

The colorful paint that was originally applied to the temple is now only mottled and remnant. However, the temple after being unearthed still looks graceful and luxurious, which is breathtaking.

The main decoration of the temple is a series of huge serpent-headed statues that protrude from the stone walls; others line the grand central staircase.

They look a bit like human reptiles, with long mouths and pointed teeth, and even a mustache on their lips.

Each serpent's neck is surrounded by a ring of intricately carved feathers - Quetzalcoatl's most prominent symbol.

Harlesden pointed out in his report that there is obviously a complex mathematical relationship between the main buildings listed on both sides of the "Road of the Dead".

In fact, this relationship extends beyond the axis.

What it shows is that the original architects designed Teotihuacan as a model of the solar system, with the dimensions of each part in a certain and precise proportion to the solar system itself.

According to Harlesden's inference, if we regard the center line of the Quetzalcoatl Temple as the position of the sun, then starting from here, the buildings listed along the axis of the "Road of the Dead" seem to show

The correct orbital distances of the stars in the solar system.

These include: the four planets close to the Sun, the asteroid group between Mars and Jupiter, Jupiter, Saturn (represented by the "Sun" pyramid), Uranus (represented by the "Moon" pyramid), Neptune, and Pluto - represented

The buildings of the last two planets are located a few kilometers north of the ancient city and are still buried under the mounds⑦.
