as much religious symbols as astronomical calendars, it. being well known that the Egyptians blended astronomy with their mythology.
CHRONOLOGY. The precession of the equinoxes has also been employed in solving several interesting chronological problems; we ascertain the period when Hesiod flourished, assuming as data the following lines taken from his Opera et Dies:
6. When from the solstice sixty wintry days,
Then first to gild the dusky evening skies.” Arcturus, the star her ereferred to, is of the first magnitude in the constellation Boötes, which now rises about a hundred days after the winter solstice to Ascra, (the birth-place of Hesiod) a little village of Bæotia, at the foot of Mount Helicon, according to Ptolemy in latitude 37° 45' north; this increase of 40 days, is equal to 39° which reduced to seconds, and divided by the annual precession, gives 2740 years since the time of Hesiod, which is as close an approximation to collateral testimony as this species of calculation can furnish.

Lord Byron. Astronomy is the very region in which the spirit of poetry finds itself in its own element; it there spreads abroad its pinions and largely roams from star to star, from system to system, exulting amidst the magnificence of interminable space. The following are a few gems which sparkle in the coronet of the genius of astronomy:
O that I were the great soul of a world !
A glory in space!
Sublime on its race!
Encircled with joy,
There take thy stand, my spirit ;-spread
The Sun, rejoicing round the earth, announced
By night-fall shaded,
