A quantitative astronomical analysis of the Orion Correlation Theory
  The link between the three major Giza pyramids and the stars of the Orion Belt has been since long time the subject of various qualitative speculations. In this framework an important role is played by a controversial theory, the so-called "Orion Correlation Theory" (OCT), according to which a perfect coincidence would exist between the mutual positions of the three stars of the Orion Belt and those of the main Giza pyramids.   In the present paper the OCT has been subjected to some quantitative astronomical and astrophysical verifications, in order to assess its compatibility with the results of both naked-eye astrometry and photometry. In particular, a linear correlation is found between the height of such monuments and the present brightness of the Orion Belt stars. According to these analyses it is possible to conclude that the OCT is not incompatible with what expected for the stars of the Orion Belt on the basis of naked-eye astrometry and photometry, as well as of the stellar evolution theory.
