Kitap 6
The clouds suffuse with leaping light the lands,
And the storm flashes with tremulous elan:
When the wind hath invaded a cloud, and, whirling there,
Hath wrought (as I have shown above) the cloud
5
Into a hollow with a thickened crust,
It becomes hot of own velocity:
Just as thou seest how motion will o'erheat
And set ablaze all objects,- verily
A leaden ball, hurtling through length of space,
10
Even melts. Therefore, when this same wind a-fire
Hath split black cloud, it scatters the fire-seeds,
Which, so to say, have been pressed out by force
Of sudden from the cloud;- and these do make
The pulsing flashes of flame; thence followeth
15
The detonation which attacks our ears
More tardily than aught which comes along
Unto the sight of eyeballs. This takes place-
As know thou mayst- at times when clouds are dense
And one upon the other piled aloft
