We hear of one magician who, about the year Fifteen Hundred, made a box with a glass cover that magnified the contents. This great man would catch a flea and show it to the people. Then he would place the flea in the box and show it to them, and they would see that it had grown enormously in an instant. The man could make it big or little, by just taking off and putting on the cover of the box!
This individual worked wonders for a consideration, but Fate overtook him and he was smothered under a feather bed for having too much wizard in his cosmos. A wizard, be it known, is a male witch, and the Bible says, "Thou shalt not suffer a witch to live," although it does not say anything about wizards.
But please note this: the wizard who had that magic box and flea had really the first microscope.
Galileo bought a pair of "magic glasses," or spectacles, about the year Sixteen Hundred Seven; and his action, in so doing, was freely criticized.
On a visit to Venice, where glass had been manufactured since long before the Flood, Galileo was looking through one of the glass-factories, just as visitors do now, and one of the workmen showed him a peculiar piece of glass which magnified the hairs on the back of his hand many times.
In a very few days after this, Galileo heard that a Dutch spectacle-maker had placed certain queer-shaped pieces of glass in a tube, and offered to sell this tube to the Government, so by its use, soldiers could see the movements of an enemy many miles away.
That night Galileo did not close his eyes in sleep. He thought out a plan by which he could place pieces of glass in a tube, and bring the stars close to the earth. By daylight the whole plan was clear in his mind, and he hastened to the shop of the glassmakers.
There, two lenses were made, one plano-convex, and the other plano-concave, and these were placed in a tube made of sheet copper. It was tested on distant objects; and behold! they were magnified by three. Would this tube show the stars magnified? Galileo knew of no reason why it should not, but he paced his room in hot impatience, waiting for the night to come with its twinkling wonders, that he might verify his convictions. When the first yellow star appeared in the West, Galileo turned his tube upon it, and behold! instead of twinkling points of light, he saw a round mass--a world--moving through space, and not a scintillating object with five points. The twinkling spikes, or points, were merely an optical illusion of the unaided senses.
