EXPLANATION OF THE PLATE INTENDED TO ILLUSTRATE THE RISE AND FALL OF NATIONS.
In the chart, at the beginning of the work, the lines, from top to bottom, represent the division of time into centuries, each indicating the year, marked under and above it, in the same way that has been adopted in Dr. Priestley's Chart of Universal History, in works of chronology, and in statements of commerce and finance.
The countries that have flourished, whether by commerce, or any other means are supposed to be represented by the parallel spaces from right to left, according to the names written on the right hand.
The rise of the black part, something like a distant range of low mountains, shews at what periods the country was great; when its greatness began and when it ended. This plan would be unexceptionally correct, if the materials for it could be procured; but if they were, it would not lead to any very different conclusion from what it does in its present state. The times, when the elevation began, and its duration are exact. The rises and falls are, as nearly as I am able, estimated from existing documents.
The part shaded of a darkish colour, and growing gradually lighter at both edges, represent those centuries of ignorance which succeeded the fall of the Roman empire. [end of page #78]
At the bottom, on the part not stained, is a chronological list of events, inventions, and discoveries, connected with the subject. Those which are not, however, important or curious, have no place.
The commerce of France, Britain, Russia, and America, are upon a true scale with respect to their proportional amount, as well as to their rise and progress. The others are not, owing to want of documents; but, as before observed, the amount has very little to do with the subject; the business is to see how wealth and power were divided at any particular time, if they were rising or falling, or if they were at their height, comparing them with the manners of the people at the time.
This is the use of the chart, as to the representation of individual places and nations.
The general conclusion is, from taking the whole together, that wealth and power have never been long permanent in any place. That they never have been renewed when once destroyed, though they have had rises and falls, and that they travel over the face of the earth, something like a caravan of merchants. On their arrival, every thing is found green and fresh; while they remain all is bustle and abundance, and, when gone, all is left trampled down, barren, and bare.
This chart is a sort of a picture, intended to make those migrations and change of place distinct and easily conceived, on which the whole of this book has been occupied. Being once acquainted with the changes that have taken place, we may more accurately compare them with the state of this country at the present time. Those who will take the trouble to read Ferguson's History of the Roman Republic, and Gibbon's Decline and Fall of the Empire, may form a judgement of the accuracy or inaccuracy of the chart.
