For when the sun is midway on his course
Between the blasts of northwind and of south,
Heaven keeps his two goals parted equally,
By virtue of the fixed position old
Of the whole starry Zodiac, through which
That sun, in winding onward, takes a year,
Illumining the sky and all the lands
With oblique light--as men declare to us
Who by their diagrams have charted well
Those regions of the sky which be adorned
With the arranged signs of Zodiac.
Or else, because in certain parts the air
Under the lands is denser, the tremulous
Bright beams of fire do waver tardily,
Nor easily can penetrate that air
Nor yet emerge unto their rising-place:
For this it is that nights in winter time
Do linger long, ere comes the many-rayed
Round Badge of the day. Or else because, as said,
In alternating seasons of the year
Fires, now more quick, and now more slow, are wont
To stream together,--the fires which make the sun
To rise in some one spot--therefore it is
That those men seem to speak the truth [who hold
A new sun is with each new daybreak born].

The moon she possibly doth shine because
Strook by the rays of sun, and day by day
May turn unto our gaze her light, the more
She doth recede from orb of sun, until,
Facing him opposite across the world,
She hath with full effulgence gleamed abroad,
And, at her rising as she soars above,
Hath there observed his setting; thence likewise
She needs must hide, as 'twere, her light behind
By slow degrees, the nearer now she glides,
Along the circle of the Zodiac,
From her far place toward fires of yonder sun,--
As those men hold who feign the moon to be
Just like a ball and to pursue a course
Betwixt the sun and earth. There is, again,
Some reason to suppose that moon may roll
With light her very own, and thus display
The varied shapes of her resplendence there.
For near her is, percase, another body,
Invisible, because devoid of light,
Borne on and gliding all along with her,
Which in three modes may block and blot her disk.
Again, she may revolve upon herself,
Like to a ball's sphere--if perchance that be--
One half of her dyed o'er with glowing light,
And by the revolution of that sphere
She may beget for us her varying shapes,
Until she turns that fiery part of her
Full to the sight and open eyes of men;
Thence by slow stages round and back she whirls,
Withdrawing thus the luminiferous part
Of her sphered mass and ball, as, verily,
The Babylonian doctrine of Chaldees,
Refuting the art of Greek astrologers,
Labours, in opposition, to prove sure--
As if, forsooth, the thing for which each fights,
Might not alike be true,--or aught there were
Wherefore thou mightest risk embracing one
More than the other notion. Then, again,
Why a new moon might not forevermore
Created be with fixed successions there
Of shapes and with configurations fixed,
And why each day that bright created moon
Might not miscarry and another be,
In its stead and place, engendered anew,
'Tis hard to show by reason, or by words
To prove absurd--since, lo, so many things
Can be create with fixed successions:
Spring-time and Venus come, and Venus' boy,
The winged harbinger, steps on before,
And hard on Zephyr's foot-prints Mother Flora,
Sprinkling the ways before them, filleth all
With colours and with odours excellent;
Whereafter follows arid Heat, and he
Companioned is by Ceres, dusty one,
And by the Etesian Breezes of the north;
Then cometh Autumn on, and with him steps
Lord Bacchus, and then other Seasons too
And other Winds do follow--the high roar
Of great Volturnus, and the Southwind strong
With thunder-bolts. At last earth's Shortest-Day
Bears on to men the snows and brings again
The numbing cold. And Winter follows her,
His teeth with chills a-chatter. Therefore, 'tis
The less a marvel, if at fixed time
A moon is thus begotten and again
At fixed time destroyed, since things so many
Can come to being thus at fixed time.
Likewise, the sun's eclipses and the moon's
Far occultations rightly thou mayst deem

As due to several causes. For, indeed,
Why should the moon be able to shut out
Earth from the light of sun, and on the side
To earthward thrust her high head under sun,
Opposing dark orb to his glowing beams--
And yet, at same time, one suppose the effect
Could not result from some one other body
Which glides devoid of light forevermore?
Again, why could not sun, in weakened state,
At fixed time for-lose his fires, and then,
When he has passed on along the air
Beyond the regions, hostile to his flames,
That quench and kill his fires, why could not he
Renew his light? And why should earth in turn
Have power to rob the moon of light, and there,
Herself on high, keep the sun hid beneath,
Whilst the moon glideth in her monthly course
Athrough the rigid shadows of the cone?
--
And yet, at same time, some one other body
Not have the power to under-pass the moon,
Or glide along above the orb of sun,
Breaking his rays and outspread light asunder?
And still, if moon herself refulgent be
With her own sheen, why could she not at times
In some one quarter of the mighty world
Grow weak and weary, whilst she passeth through
Regions unfriendly to the beams her own?




ORIGINS OF VEGETABLE AND ANIMAL LIFE


And now to what remains! --Since I've resolved
By what arrangements all things come to pass
Through the blue regions of the mighty world,--
How we can know what energy and cause
Started the various courses of the sun
And the moon's goings, and by what far means
They can succumb, the while with thwarted light,
And veil with shade the unsuspecting lands,
When, as it were, they blink, and then again
With open eye survey all regions wide,
Resplendent with white radiance--I do now
Return unto the world's primeval age
And tell what first the soft young fields of earth
With earliest parturition had decreed
To raise in air unto the shores of light
And to entrust unto the wayward winds.
In the beginning, earth gave forth, around
The hills and over all the length of plains,
The race of grasses and the shining green;
The flowery meadows sparkled all aglow
With greening colour, and thereafter, lo,
Unto the divers kinds of trees was given
An emulous impulse mightily to shoot,
With a free rein, aloft into the air.
As feathers and hairs and bristles are begot
The first on members of the four-foot breeds
And on the bodies of the strong-y-winged,
Thus then the new Earth first of all put forth
Grasses and shrubs, and afterward begat
The mortal generations, there upsprung--
Innumerable in modes innumerable--
After diverging fashions. For from sky
These breathing-creatures never can have dropped,
Nor the land-dwellers ever have come up
Out of sea-pools of salt. How true remains,
How merited is that adopted name
Of earth--"The Mother! "--since from out the earth
Are all begotten. And even now arise
From out the loams how many living things--
Concreted by the rains and heat of the sun.
Wherefore 'tis less a marvel, if they sprang
In Long Ago more many, and more big,
Matured of those days in the fresh young years
Of earth and ether. First of all, the race
Of the winged ones and parti-coloured birds,
Hatched out in spring-time, left their eggs behind;
As now-a-days in summer tree-crickets
Do leave their shiny husks of own accord,
Seeking their food and living. Then it was
This earth of thine first gave unto the day
The mortal generations; for prevailed
Among the fields abounding hot and wet.
And hence, where any fitting spot was given,
There 'gan to grow womb-cavities, by roots
Affixed to earth. And when in ripened time
The age of the young within (that sought the air
And fled earth's damps) had burst these wombs, O then
Would Nature thither turn the pores of earth
And make her spurt from open veins a juice
Like unto milk; even as a woman now
Is filled, at child-bearing, with the sweet milk,
Because all that swift stream of aliment
Is thither turned unto the mother-breasts.
There earth would furnish to the children food;
Warmth was their swaddling cloth, the grass their bed
Abounding in soft down.
