It followed from this that the Sun, like the Moon, not only moved with
the general host of the stars, but also among them. If an observer
looks out from any fixed station and watches the rising of some bright
star, night after night, he will notice that it always appears to rise
in the same place; so too with its setting. From any given observing
station the direction in which any particular star is observed to rise
or set is invariable.
Not so with the Sun. We are accustomed to say that the Sun rises in
the east and sets in the west. But the direction in which the Sun
rises in midwinter lies far to the south of the east point; the
direction in which he rises in midsummer lies as far to the north. The
Sun is therefore not only moving with the stars, but among them. This
gradual change in the position of the Sun in the sky was noticed in
many ancient nations at an early time. It is referred to in Job
xxxviii. 12: "Hast thou commanded the morning since thy days; and
caused the dayspring to know his place?"
And the apparent path of the Sun on one day is always parallel to its
path on the days preceding and following. When, therefore, the Sun
rises far to the south of east, he sets correspondingly far to the
south of west, and at noon he is low down in the south. His course
during the day is a short one, and the daylight {13} is much shorter
than the night, and the Sun at noon, being low down in the sky, has not
his full power. The cold and darkness of winter, therefore, follows
directly upon this position of the Sun. These conditions are reversed
when the Sun rises in the north-east. The night is short, the daylight
prolonged, and the Sun, being high in the heavens at noon, his heat is
felt to the full.
Thus the movements of the Sun are directly connected with the changes
of season upon the Earth. But the stars also are connected with those
seasons; for if we look out immediately after it has become dark after
sunset, we shall notice that the stars seen in the night of winter are
only in part those seen in the nights of summer.
