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.

The Netherlanders had wrung their original fatherland out of the grasp of the ocean.  They had confronted for centuries the wrath of that ancient tyrant, ever ready to seize the prey of which he had been defrauded.

They had waged fiercer and more perpetual battle with a tyranny more cruel than the tempest, with an ancient superstition more hungry than the sea.  It was inevitable that a race, thus invigorated by the ocean, cradled to freedom by their conflicts with its power, and hardened almost to invincibility by their struggle against human despotism, should be foremost among the nations in the development of political, religious, and commercial freedom.

The writer now takes an affectionate farewell of those who have followed him with an indulgent sympathy as he has attempted to trace the origin and the eventful course of the Dutch commonwealth.  If by his labours a generous love has been fostered for that blessing, without which everything that this earth can afford is worthless—­freedom of thought, of speech, and of life—­his highest wish has been fulfilled.  Etext editor’s bookmarks:
