A moment since, it catches fire before
'Thas touched the flame, and in same wise a torch?
And many another object flashes aflame
When at a distance, touched by heat alone,
Before 'tis steeped in veritable fire.
This, then, we must suppose to come to pass
In that spring also.
Now to other things!
And I'll begin to treat by what decree
Of nature it came to pass that iron can be
By that stone drawn which Greeks the magnet call
After the country's name (its origin
Being in country of Magnesian folk).
This stone men marvel at; and sure it oft
Maketh a chain of rings, depending, lo,
From off itself! Nay, thou mayest see at times
Five or yet more in order dangling down
And swaying in the delicate winds, whilst one
Depends from other, cleaving to under-side,
And ilk one feels the stone's own power and bonds--
So over-masteringly its power flows down.
In things of this sort, much must be made sure
Ere thou account of the thing itself canst give,
And the approaches roundabout must be;
Wherefore the more do I exact of thee
