▲ The Mysterious Relationship Between Sirius and the Nile
In ancient Egypt, Sirius would set below the horizon once each year,
disappearing from view for about 70 days—
Then, around July, just as it reappeared in the eastern sky,
the Nile River would flood.

It was an incredibly mysterious event,
as if the return of the star and the arrival of the water were connected.
And this is where“water” becomes the key theme.

▲ Life and Prosperity Brought by “Water”
Egypt is a vast desert region,
and the Nile River was its source of life-sustaining water.

When the Nile River floods,
it deposits fertile soil, allowing crops to flourish.

In other words, this was not merely a natural phenomenon;
it was an event that began with water and brought forth “life” and “prosperity”—
an event of tremendous importance.

▲ The Deification of Sirius
Sirius is also depicted as a god.
Among the best-known figures are—
・Isis
She is the goddess of fertility in Egyptian mythology
and the wife of Osiris.
She symbolizes life, rebirth, and motherhood.

・Sopdet
The goddess who personifies Sirius itself.
She is depicted with a star upon her head and is considered to govern fertility.

Both goddesses are closely associated with “fertility,”
and symbolize the essence of Sirius worship.

Taking all of this together,
Sirius was more than just a “bright star”;
it was regarded as
・a being that brings water
・a being that nurtures life
・a being that guides prosperity
and held special significance in ancient Egypt.
In light of this, it is understandable that Sirius was connected to the structure of the pyramids.
