I dreamed that I was conveyed into a wide and boundless plain, that was covered with prodigious multitudes of people, which no man could number. In the midst of it there stood a mountain, with its head above the clouds. The sides were extremely steep, and of such a particular structure, that no creature which was not made in a human figure could possibly ascend it. On a sudden there was heard from the top of it a sound like that of a trumpet, but so exceeding sweet and harmonious, that it filled the hearts of those who heard it with raptures, and gave such high and delightful sensations, as seemed to animate and raise human nature above itself. This made me very much amazed to find so very few in that innumerable multitude who had ears fine enough to hear or relish this music with pleasure; but my wonder abated when, upon looking round me, I saw most of them attentive to three Syrens, clothed like goddesses, and distinguished by the names of Sloth, Ignorance, and Pleasure. They were seated on three rocks, amidst a beautiful variety of groves, meadows, and rivulets that lay on the borders of the mountain. While this base and grovelling multitude of different nations, ranks, and ages were listening to these delusive deities, those of a more erect aspect and exalted spirit separated themselves from the rest, and marched in great bodies towards the mountain from whence they heard the sound, which still grew sweeter the more they listened to it. On a sudden methought this select band sprang forward, with a resolution to climb the ascent, and follow the call of that heavenly music. Every one took something with him that he thought might be of assistance to him in his march. Several had their swords drawn, some carried rolls of paper in their hands, some had compasses, others quadrants, others telescopes, and others pencils. Some had laurels on their heads, and others buskins on their legs; in short, there was scarce any instrument of a mechanic art, or liberal science, which was not made of use on this occasion. My good demon, who stood at my right hand during this course of the whole vision, observing in me a burning desire to join that glorious company, told me, "he highly approved that generous ardour with which I seemed transported; but at the same time advised me to cover my face with a mask all the while I was to labour on the ascent." I took his counsel, without inquiring into his reasons. The whole body now broke into different parties, and began to climb the precipice by ten thousand different paths. Several got into little alleys, which did not reach far up the hill before they ended, and led no further; and I observed that most of the artizans, which considerably diminished our number, fell into these paths.
