Here is what archaeologists had to say about this particular find:

Ancient Egyptians wrote Calendars of Lucky and Unlucky Days that assigned astronomically influenced prognoses for each day of the year. The best preserved of these calendars is the Cairo Calendar dated to 1244 – 1163 BC (Ramesside Period). According to scientists at the University of Helsinki, this papyrus is the oldest preserved historical document of naked eye observations of a variable star, the eclipsing binary star Algol.

The analysis revealed that the periods of the variable star Algol (2.85 days) and the Moon (29.6 days) strongly regulate the actions of deities in this calendar.

“We show that Algol was represented as Horus and thus signified both divinity and kingship,” the researchers said.

“The texts describing the actions of Horus are consistent with the course of events witnessed by any naked eye observer of Algol.”

And here is a fascinating video on decoding heiroglyphics.  The archaeologist who gives the talk has been

interested in this area since he was a boy:

How did Egyptologists decipher hieroglyphics? Jean-Francois Champollion started working on decoding the ancient Egyptian writing when he was 9 years old at the end of the 18th century. When the Rosetta stone was discovered, he was able to decode the script and read the inscriptions. This opened up the world to a wealth of ancient knowledge and history as other scholars tackled the mysteries of Babylonian, Sumerian, Ugaritic, Hurian and Assyrian.

We hope you enjoy the video.
