  the succeeding rulers of Babylon then the rulers
  of Persia next the Greek rulers of Egypt to
  Cleopatra and concluding with the Roman rulers
  of Egypt from Augusta to Antoninus Pius (A.D.

• Value he has recorded over eighty solar, lunar,
  and planetary positions together with their
  dates, which may be coordinated with the years of
