TWO INSCRIPTIONS FROM OLD SUNDIALS
Life's but a shade: man is but dust;
The dyall sayes that dyall we must.

Helmut,
Regarding the occurrence of The Seasons, I think I was mentioning a

Precession e.g., with the Equinoxes shifting West and the Longitude of
Perihelion shifting East the Summer Solstice and Perihelion w
Arthur,
You are right regarding the relative small changes in the values of
Obliquity and Eccentricity over the period of a precession cycle. However, it
