Bootes' fall will send thee; then begin,
Pursue thy sowing till half the frosts be done.
Therefore it is the golden sun, his course
Into fixed parts dividing, rules his way
Through the twelve constellations of the world.
Five zones the heavens contain; whereof is one
Aye red with flashing sunlight, fervent aye
From fire; on either side to left and right
Are traced the utmost twain, stiff with blue ice,
And black with scowling storm-clouds, and betwixt
These and the midmost, other twain there lie,
By the Gods' grace to heart-sick mortals given,
And a path cleft between them, where might wheel
On sloping plane the system of the Signs.
And as toward Scythia and Rhipaean heights
The world mounts upward, likewise sinks it down
Toward Libya and the south, this pole of ours
Still towering high, that other, 'neath their feet,
By dark Styx frowned on, and the abysmal shades.
Here glides the huge Snake forth with sinuous coils
'Twixt the two Bears and round them river-wise-
The Bears that fear 'neath Ocean's brim to dip.
There either, say they, reigns the eternal hush
Of night that knows no seasons, her black pall
Thick-mantling fold on fold; or thitherward
From us returning Dawn brings back the day;
And when the first breath of his panting steeds
On us the Orient flings, that hour with them
Red Vesper 'gins to trim his his 'lated fires.
Hence under doubtful skies forebode we can
