ems or with whatever one
pleases you more, and judge which one seems more consonant with
nature when all things are examined. But if you aren't able to
reconcile this theory with some astronomical observations or
physical experiments and think it should be eliminated from
the group of theories, see that I might know this while life is
still my companion, so that I might think with you, if this is
possible. Also, so that, in gratitude for the detected or
perhaps hidden error, I might speak or write, and you won't
have to shout in vain in bold ridicule and with no applause
after the fleeing shades of the dead and the mute ashes. But,
if you object that the daily motion of the revolving earth and
the annual motion of its whirling axis do not sufficiently
agree with certain texts of Sacred Scripture, and if those
things which the Copernicans and the Longomontanists say do not
convince you, then reject my whole system as an old wives'
tale.

GLOSSARY

ANOMOLIA or anomaly, is the angular distance of a planet from its
perihelion (that point of the orbit of a planet which is nearest to the
sun) as seen from the sun.

AEQUINOCTIUM or the equinox, is the time in which days and nights are
equal in the space of hours. There are two equinoxes: the spring
equinox--c. 8 calends of April in the sign of Aries; and the fall
equinox--c. 10 calends of October in the sign of Libra.

AERAS is derived from _aera_, _aerae_, which originally meant a given
number, usually used in regard to money. The word was later extended to
mean a number used in any calculation, and finally it came to mean a
certain time from which subsequent times were counted, e.g., _Anno
Domini_, after the Birth of Christ.

COLURI or the Colures, which are two circles in the heavenly sphere,
passing through the poles of the world and cutting each other at right
angles: the one passes through the equinoctial points of Aries and Libra
and is called _Colurus Aequinoctiorum_ or equinoctial colure; the other
touches the _solstitialia_ of Cancer and Capricorn and is called
_Colurus Solstitiorum_ or solstitial colure. They are called _Colurus_,
which is translated as "mutilated tails," for the part which emerges in
the Antarctic is not visible and is quasitruncated.

ECLIPTICA or the ecliptic, is an imaginary line in the heavens in which
the sun was
