The legendary pyramids have intrigued researchers, not only for their secret voids and hidden chambers, but also for the fact that the ancient Egyptians were able to build such impressive monuments using the resources of the past. So one of the greatest mysteries is the impressive alignment of the pyramids.
In particular, the Great Pyramid of Giza has straight lines of great precision at 138.8 meters on each side and is aligned with the cardinal points, north, south, east and west. The accuracy is approaching 4 minutes of arc or 1/15th of a degree if you will. Something extremely difficult in an age without drones and computers.
There have been many speculations about how they achieved this, using for example Polaris or the shadow of the Sun, but it is not yet clear how they calculated it.
The most recent method, published in 2017, suggests a much simpler way.
Experimenting with the first day of the autumn equinox in 2016, they used a gnomon to create a shadow. They marked the top of the shadow at regular intervals throughout the day, forming a curve. At the end of the day, using a rope tied to the gnomon, they saw where it intersected the curve, connected them, and created a near-perfect line from sunrise to sunset.
Thus, all the Egyptians would have needed to align their pyramids would have been a sunny day.[/B] Although this method suggests that it could have been used, unfortunately we still have no evidence of the technique they eventually followed.
[/P][/QUOTE][BR][/QUOTE][BR][BR][BR]The Egyptians unfortunately left us very little evidence. No engineering documents or architectural drawings have been found with technical explanations that would prove how the ancient Egyptians aligned the pyramids.
The research was published in The Journal of Ancient Egyptian Architecture.
