TimeLine of the World based on Astronomy
LexiLine.com has now been completely revised and updated and
http://www.lexiline.com/lexiline/lexi760.htm
presents what I consider to be the most accurate ancient
chronology of the ancient world yet produced, based in large part on
astronomical calibration of ancient landmark dates.
However, this is only MY opinion.
This chronology should not be regarded as infallible, and small
corrections will surely be made in future time, but I will allege
here that the other chronologies out there, especially those of
mainstream scholars, are far more off the mark and are based on
spurious, far less reliable evidence.
