And as in this gentlest of arts, so also in the dread science of war, the republic had been the instructor of mankind.
The youthful Maurice and his cousin Lewis William had so restored and improved the decayed intelligence of antique strategy, that the greybeards of Europe became docile pupils in their school. The mathematical teacher of Prince Maurice amazed the contemporary world with his combinations and mechanical inventions; the flying chariots of Simon Stevinua seeming products of magical art.
Yet the character of the Dutch intellect was averse to sorcery. The small but mighty nation, which had emancipated itself from the tyranny of Philip and of the Holy Inquisition, was foremost to shake off the fetters of superstition. Out of Holland came the first voice to rebuke one of the hideous delusions of the age. While grave magistrates and sages of other lands were exorcising the devil by murdering his supposed victims, John Wier, a physician of Grave, boldly denounced the demon which had taken possession, not of the wizards, but of the judges.
The age was lunatic and sick, and it was fitting that the race which had done so much for the physical and intellectual emancipation of the world, should have been the first to apply a remedy for this monstrous madness. Englishmen and their descendants were drowning and hanging witches in New England, long after John Wier had rebuked and denounced the belief in witchcraft.
It was a Zeelander, too; who placed the instrument in the hand of Galileo by which that daring genius traced the movements of the universe, and who, by another wondrous invention, enabled future discoverers to study the infinite life which lies all around us, hidden not by its remoteness but it's minuteness. Zacharias Jansens of Middelburg, in 1590, invented both the telescope and the microscope.
The wonder-man of Alkmaar, Cornelius Drebbel, who performed such astounding feats for the amusement of Rudolph of Germany and James of Britain, is also supposed to have invented the thermometer and the barometer. But this claim has been disputed. The inventions of Jansens are proved.
Willebrod Snellius, mathematical professor of Leyden, introduced the true method of measuring the degrees of longitude and latitude, and Huygens, who had seen his manuscripts, asserted that Snellius had invented, before Descartes, the doctrine of refraction.
But it was especially to that noble band of heroes and martyrs, the great navigators and geographical discoverers of the republic, that science is above all indebted.
Nothing is more sublime in human story than the endurance and audacity with which those pioneers of the sixteenth and seventeenth centuries confronted the nameless horrors of either pole, in the interests of commerce, and for the direct purpose of enlarging the bounds of the human intellect.
The achievements, the sufferings, and the triumphs of Barendz and Cordes, Heemskerk, Van der Hagen, and many others, have been slightly indicated in these pages. The contributions to botany, mineralogy, geometry, geography, and zoology, of Linschoten, Plancius, Wagenaar, and Houtmann, and so many other explorers of pole and tropic, can hardly be overrated.
