Lucid gems are made of water; just as Crystal, which has been concreted from clear water, not always by a very great cold, as some used to judge, and by very hard frost, but sometimes by a less severe one, the nature of the soil fashioning it, the humour or juices being shut up in definite cavities, in the way in which spars are produced in mines.
English physician, physicist and natural philosopher (1544-1603)
William Gilbert (24 May, 1544 – 30 November, 1603) was an English natural philosopher and royal physician to England's Elizabeth I and to James VI and I. He studied the earth's magnetism and properties of the compass, such as magnetic dip, using the model of a terrella. He is highly regarded for original experiments in electricity and magnetism and for his advocacy of the experimental method. He preceded Francis Bacon in his opposition to the methods of Scholasticism with its emphasis on dialectic and the syllogism as a method of discovery. Gilbert was an early defender of Nicolaus Copernicus, not with regard to the sun-centered planetary system, but as to the diurnal motion of the earth. His theory of the magnetic influences of the sun, moon and planets influenced Kepler's preconception of gravity.

The electric effluvia differ much from air, and as air is the earth's effluvium, so electric bodies have their own distinctive effluvia; and each peculiar effluvium has its own individual power of leading to union, its own movement to its origin, to its fount, and to the body emitting the effluvium.

Neither in any if the stars, nor in the sun, nor in the planets that are most operant in the world, can organs be disntinguished or imagined by us; nevertheless, they live and endow with life small bodies at the earth's elevated points. If there is aught of which man may boast, that of a surety is soul, is mind; and the other animals, too, are ennobled by soul; even God, by whose rod all things are governed, is soul.
How far away from the earth are those remotest of stars: they are beyond the reach of eye, or man's devices, or man's thought. What an absurdity is this motion (of spheres). He also argues for the extreme variability of the distance to the various heavenly bodies and states that situated "in thinnest aether, or in the most subtle fifth essence, or in vacuity - how shall the stars keep their places in the mighty swirl of these enormous spheres composed of a substance of which no one knows aught?
We, therefore, having directed our inquiry toward a cause that is manifest, sensible, and comprehended by all men, do know that the earth rotates on its own poles, proved by many magnetical demonstrations to exist. For not in virtue only of its stability and its fixed permanent position does the earth possess poles and verticity; it might have had another direction, as eastward or westward, or toward any other quarter. By the wonderful wisdom of the Creator, therefore, forces were implanted in the earth, forces primarily animate, to the end the globe might, with steadfastness, take direction, and that the poles might be opposite, so that on them, as at the extremities of an axis, the movement of diurnal rotation might be performed.
