A vast opening exposed to my eyes in an immense cavern, an abyss of fire. The devouring flame rapidly consumed the combustible matter with which the arched roofs of the abyss were impregnated. A thick smoke mixed with fiery sparks, diffused itself to a great distance. From time to time, the calcined stones fell down by pieces, and the liquified metals formed flaming streams. Sometimes whole rocks, rent from the tops of the vaults, gave passage to water, which poured down in boiling streams. The moment the water touched the calcined matters and melted minerals, it caused most shocking detonations: The concavities of the globe resounded, their foundations were shaken: And I conceived that such was the cause of those terrible earth-quakes, that have destroyed so many countries, and swallowed up so many cities.
I was soon in darkness again; for I still went on. Every moment I should have been destroyed, if the Prefect of Giphantia had not watched over me. I saw him no more: But his promise was with me: And the dangers, I had escaped, heartened me against those I had still to undergo. By degrees I took courage, and became so easy as to make some reflections.
Alas! said I, through a frightful desart I came into the most beautiful mansions in the world, and I am now going thence through gulfs, abysses, and vulcanos. Good and evil closely follow one another. It is thus, the light of the day and darkness of the night, the frosts of the winter and the flowers of the spring, the gentle zephyrs and the raging storms, succeed one another. However, by this strange concatenation, is formed the enchanting prospect of nature. Let us not doubt it: The natural world, notwithstanding its disorders, is the master-piece of infinite wisdom; the moral world, in spite of its stains, is worthy the admiration of the philosopher: And Babylon, with all its faults, is the chief city of the world.
At last, after many days of subterraneous navigation, I once more saw the light; I came out of these terrible vaults, and the last current landed me upon a maritime coast. The serenity of the air was not ruffled with the wind; the calm sea shone with the rays of the rising-sun; and, like a tender wife who stretches out her arms, and sweetly smiles on a beloved husband, the earth seemed to resume new life at the return of that glorious orb, from whence springs all its fertility. By degrees, my troubled senses were calmed: I looked round me, and found myself in my own country, six hundred furlongs north-west from Babylon, to which city I address and dedicate this narrative of my hazardous travels.
