Astronomy of the observation of Sirius as
norm for choosing the dating of the 18th Dynasty ---Do not let any article on Astronomy
make you unstable about the High Chronology for the 18th Dynasty. ---There is a star Sirius that appeared
every 1456 years or 1460 years. ---There is the issues whether scribes
counted co-regency included or excluded. ---Then there is a third element: from
where was the observation made. ---There are three observation points
possibilities in Egypt: Heliopolis, Thebes and Elephantine. ---Memphis or Heliopolis lies in the Nile
Delta in the North. ---Thebes is in the center of Egypt. ---Elephantine is on the Nile but in the
South of the country. ---A scholar Ward indicated that if the
observation in papyrus Ebers was made from Heliopolis it was in 1541 BC if the length
was 1456 years and 1545 BC if the length of Sirius cycle is 1460 years. ---If the observation was made from
Thebes, the Ebers papyrus is talking about an event that occurred in 1523 or
1527 BC depending how long the Sirius cycle is. ---If the observation is made from
Elephantine, then the recording of the Papyrus Ebers of the 9th year
of Amenhotep I would have been in 1519 BC or 1523, again depending on the length
of the cycle of Sirius, 1456 years or 1460 years. ---So if scholars with a low chronology is
arguing for the date 1519 BC as the 9th year of Amenhotep I, then
smile nicely and remember this principle about astronomical reckonings in the
literature of Egypt.
