Charles H. Spurgeon on Psalms 135:18

Like unto them. A singular phenomenon, known as the Spectre of the Brocken, is seen on a certain mountain in Germany. The traveller who at dawn stands on the topmost ridge beholds a colossal shadowy spectre. But in fact it is only his own shadow projected upon the morning mists by the rising sun; and it imitates, of course, every movement of its creator. So heathen nations have mistaken their own image for Deity. Their gods display human frailties and passions and scanty virtues, projected and magnified upon the heavens, just as the small figures on the slide of a magic lantern are projected, magnified, and illuminated upon a white sheet. —From Elan Foster's New Cyclopoedia of Illustrations, 1870.
