Dear Fer,
thank you, that you remembered me, that M.J. Hagen (1985) wrote in Bulletin
85.3
an article about the retrogration. I read it again and also W.Elsner (1989),
who
knew the article of Hagen.
As Jerusalem has a location of 32 Grad North the explantions of Hagen don¥t
solve
the problem of Achas Sundial.
W. Elsner wrote, that people can observe the retrogradiation also in northern
latitudes, when the Polos has an angle less then 20 Degrees to the inclined
plane
on horizontal and vertical sundials. He makes also suggestions for other
inclinations of the Polos.
But to solve the miracle of Achas Sundial the question was and is:
Under what conditions did the Achas Sundial work?
