Abstract
THE undoubted trend of the pyramids at 4600 B.C. was about 5 west of the present pole. Each of the data was probably set out afresh from polar observation, as that would be easier than transfer by measurement. The accuracy of work there to 12 of angle is in keeping with the accuracy of later work, as of granite planes 20 square feet in area with only inch/160 error at 3300 B.C., or of weights in eighth century A.D. with variations all within grain/200. The cause of a change of axis of about 5 per century might be due to ocean currents or to earth deformation.
