Because full many seeds of heat there be
Within the water; and, from earth itself
Out of the deeps must particles of fire
Athrough the entire fountain surge aloft,
And speed in exhalations into air
Forth and abroad (yet not in numbers enow
As to make hot the fountain). And, moreo'er,
Some force constrains them, scattered through the water,
Forthwith to burst abroad, and to combine
In flame above. Even as a fountain far
There is at Aradus amid the sea,
Which bubbles out sweet water and disparts
From round itself the salt waves; and, behold,
In many another region the broad main
Yields to the thirsty mariners timely help,
Belching sweet waters forth amid salt waves.
Just so, then, can those seeds of fire burst forth
Athrough that other fount, and bubble out
Abroad against the bit of tow; and when
They there collect or cleave unto the torch,
Forthwith they readily flash aflame, because
The tow and torches, also, in themselves
Have many seeds of latent fire. Indeed,
And seest thou not, when near the nightly lamps
Thou bringest a flaxen wick, extinguished
