They had produced the astronomical system of Copernicus, with Kepler's great additions; the astronomical discoveries and the physical investigations of Galileo; the mechanics of Stevinus and the 'De Magnete' of Gilbert; the anatomy of the great French and Italian schools and the physiology of Harvey.
The first great work on electricity and magnetism was the "De Magnete" of Gilbert, physician of Queen Elizabeth, published in 1600. Galileo, already famous in Europe, recognized in the methods of investigation used by Gilbert the ones which he had found so fruitful, and wrote of him, "I extremely praise, admire, and envy this author."
Mebbe it's poison gas, for all I know. There was a fellow in Ireland when we " Tom ignored him, and making a guess adjustment of the mixing valve, opened the gas and threw the wheel over. "No batteries magneto, huh?" "Yes, but it don't magnete. I'd ruther have a couple o' batteries that would bat." A few crankings and the little engine started, missing frightfully.
The varied results of such investigations cannot be described here. Only one of them may be mentioned the discovery that the entire sun, rotating on its axis, is a great magnet. Hence we may reasonably infer that every star, and probably every planet, is also a magnet, as the earth has been known to be since the days of Gilbert's "De Magnete."
Gilbert, who wrote De Magnete. He came afterwards unto London, and exercised his faculty in several places thereof. Winston of Gresham College, to instruct the Lord Treasurer Weston's son in arithmetick, astronomy upon the globes, and their uses.
He appears to have studied with care the admirable work of our countryman, Dr Gilbert, "De Magnete," which was published in 1600; and he recognised in the experiments and reasonings of the English philosopher the principles of that method of investigating truth which he had himself adopted.
We read of a great painting by Bularchus, of the battle of Magnete, purchased by a king of Lydia seven hundred and eighteen years before Christ. And as the subject was a battle, it must have represented the movement of figures, although we know nothing of the coloring, or of the real excellence of the work, except that the artist was paid munificently.
It is the story of this servitude only that is capable of being told, and the first weak bands were a hundred and forty-six years in forging; from the Englishman Gilbert's "De Magnete," to Franklin's Kite. During all this time, and to a great degree long after, electricity was a scientific toy.

His investigations in chemistry, although supposed to be of great importance, are mostly lost; but his great work, De Magnete, on which he labored for upwards of eighteen years, is a work of sufficient importance, as Hallam says, "to raise a lasting reputation for its author."
