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 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 A mind and ears attent. First, from all things We see soever, evermore must flow, Must be discharged and strewn about, about, Bodies that strike the eyes, awaking sight. From certain things flow odours evermore, As cold from rivers, heat from sun, and spray From waves of ocean, eater-out of walls Along the coasts. Nor ever cease to seep The varied echoings athrough the air. Then, too, there comes into the mouth at times The wet of a salt taste, when by the sea We roam about; and so, whene'er we watch The wormwood being mixed, its bitter stings. To such degree from all things is each thing Borne streamingly along, and sent about To every region round; and nature grants Nor rest nor respite of the onward flow, Since 'tis incessantly we feeling have, And all the time are suffered to descry And smell all things at hand, and hear them sound.
