Of The Nature of Things [91]
And winds are scanty in the hot, and clouds
Have not so dense a bulk. But when, indeed,
The seasons of heaven are betwixt these twain,
The divers causes of the thunderbolt
Then all concur; for then both cold and heat
Are mixed in the cross-seas of the year,
So that a discord rises among things
And air in vast tumultuosity
Billows, infuriate with the fires and winds-
Of which the both are needed by the cloud
For fabrication of the thunderbolt.
For the first part of heat and last of cold
Is the time of spring; wherefore must things unlike
Do battle one with other, and, when mixed,
Tumultuously rage. And when rolls round
The latest heat mixed with the earliest chill-
The time which bears the name of autumn- then
Likewise fierce cold-spells wrestle with fierce heats.
On this account these seasons of the year
Are nominated "cross-seas."- And no marvel
If in those times the thunderbolts prevail
And storms are roused turbulent in heaven,
Since then both sides in dubious warfare rage
Tumultuously, the one with flames, the other
With winds and with waters mixed with winds.
This, this it is, O Memmius, to see through
The very nature of fire-fraught thunderbolt;
O this it is to mark by what blind force
It maketh each effect, and not, O not
To unwind Etrurian scrolls oracular,
Inquiring tokens of occult will of gods,
Even as to whence the flying flame hath come,
Or to which half of heaven it turns, or how
Through walled places it hath wound its way,
Or, after proving its dominion there,
How it hath speeded forth from thence amain,
Or what the thunderstroke portends of ill
From out high heaven. But if Jupiter
And other gods shake those refulgent vaults
With dread reverberations and hurl fire
Whither it pleases each, why smite they not
Mortals of reckless and revolting crimes,
That such may pant from a transpierced breast
Forth flames of the red levin- unto men
A drastic lesson?- why is rather he-
O he self-conscious of no foul offence-
Involved in flames, though innocent, and clasped
Up-caught in skiey whirlwind and in fire?
Nay, why, then, aim they at eternal wastes,
And spend themselves in vain?- perchance, even so
To exercise their arms and strengthen shoulders?
Why suffer they the Father's javelin
To be so blunted on the earth? And why
Doth he himself allow it, nor spare the same
Even for his enemies? O why most oft
Aims he at lofty places? Why behold we
Marks of his lightnings most on mountain tops?
Then for what reason shoots he at the sea?-
What sacrilege have waves and bulk of brine
And floating fields of foam been guilty of?
Besides, if 'tis his will that we beware
Against the lightning-stroke, why feareth he
To grant us power for to behold the shot?
And, contrariwise, if wills he to o'erwhelm us,
Quite off our guard, with fire, why thunders he
Off in yon quarter, so that we may shun?
Why rouseth he beforehand darkling air
And the far din and rumblings? And O how
Canst thou believe he shoots at one same time
Into diverse directions? Or darest thou
Contend that never hath it come to pass
That divers strokes have happened at one time?
But oft and often hath it come to pass,
And often still it must, that, even as showers
And rains o'er many regions fall, so too
Dart many thunderbolts at one same time.
Again, why never hurtles Jupiter
A bolt upon the lands nor pours abroad
Clap upon clap, when skies are cloudless all?
Or, say, doth he, so soon as ever the clouds
Have come thereunder, then into the same
Descend in person, that from thence he may
Near-by decide upon the stroke of shaft?
And, lastly, why, with devastating bolt
Shakes he asunder holy shrines of gods
And his own thrones of splendour, and to-breaks
The well-wrought idols of divinities,
And robs of glory his own images
By wound of violence?
But to return apace,
Easy it is from these same facts to know
In just what wise those things (which from their sort
The Greeks have named "bellows") do come down,
Discharged from on high, upon the seas.
