A new study suggests that the city of Alexandria, Founded by Alexander the Great in 331 BC, It was built in such a way that it is aligned with the sunrise on the day of the birth of the famous historical figure.
Alexander was born on July 20, 356 BC., ruled at that time by the Julian calendar that differs from ours (the Gregorian) by omitting the leap years that are those that keep our calendar synchronized with the astronomical year.
The researchers found that that day in the 4th century BC, the sun makes its way almost perfectly aligned with the Canopic road, the main one of the city and that goes from east to west, differing less than half a degree outside the route of the highway.
A second star reinforced all this effect: Regulus, known as the "King's star", the brightest in the constellation of Leo and which is located near the head of the lion, which is also in perfect alignment with the same road.
That is to say: the route that both the sun take during the day, and Regulus at night, they are in perfect agreement with the main road of the city, calculating according to the Julian calendar the route that these stars followed on the day of the birth of Alexander the Great.
Professor Giulio Magli, an archaeologist at the Polytechnic Institute of Milan, explained to LiveScience that architecture based on astronomy was very prevalent in ancient times. In fact, the Great Pyramid of Giza is in almost perfect alignment with the cardinal points, to cite one example.
The egyptians that Alexander the Great conquered, were admired throughout the ancient world for his science and his mathematics, and they were the ones who associated the Sun (the god Ra) with their pharaohs, granting them a certain divine power. Here's how researchers believe Alexandria was the prototype for a series of Hellenistic cities designed as "king cities.", which tend to make explicit the divine power of their founder.
“The alignment of the city with the sun on the day of Alexander's birth was a way of incorporating into the architectural project an explicit reference to his power”Said Magli, who is examining other cities founded by Alexander the Great to see if they maintain the link with the path of the sun across the sky.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
