“Italy,” says Varro, “is the most temperate climate in Europe. The inland parts” (Gaul, Germany, and Pannonia, no doubt) “have almost perpetual winter.”
The northern parts of Spain, according to Strabo, are but ill inhabited because of the great cold.
Allowing, therefore, this remark to be just, that Europe is become warmer than formerly, how can we account for it? Plainly by no other method than by supposing that the land is at present much better cultivated, and that the woods are cleared which formerly threw a shade upon the earth and kept the rays of the sun from penetrating to it. Our northern colonies in America become more temperate in proportion as the woods are felled,[92] but in general, every one may remark that cold still makes itself more severely felt both in North and South America, than in places under the same latitude in Europe.
Saserna, quoted by Columella, affirmed that the disposition of the heavens was altered before his time, and that the air had become much milder and warmer. “As appears hence,” says he, “that many places now abound with vineyards and olive plantations which formerly, by reason of the rigour of the climate, could raise none of these productions.” Such a change, if real, will be allowed an evident sign of the better cultivation and peopling of countries before the age of Saserna;[93] and if it be continued to the present times, is a {p165} proof that these advantages have been continually increasing throughout this part of the world.
Let us now cast our eye over all the countries which were the scene of ancient and modern history, and compare their past and present situation. We shall not, perhaps, find such foundation for the complaint of the present emptiness and depopulation of the world. Egypt is represented by Maillet, to whom we owe the best account of it, as extremely populous, though he esteems the number of its inhabitants to be diminished. Syria, and the Lesser Asia, as well as the coast of Barbary, I can really own to be very desert in comparison of their ancient condition. The depopulation of Greece is also very obvious. But whether the country now called Turkey in Europe may not, in general, contain as many inhabitants as during the flourishing period of Greece may be a little doubtful. The Thracians seem then to have lived like the Tartars at present, by pillage and plunder; the Getes were still more uncivilized, and the Illyrians were no better. These occupy nine-tenths of that country, and though the government of the Turks be not very favourable to industry and propagation, yet it preserves at least peace and order among the inhabitants, and is preferable to that barbarous, unsettled condition in which they anciently lived.
Poland and Muscovy in Europe are not populous, but are certainly much more so than the ancient Sarmatia and Scythia, where no husbandry or tillage was ever heard of, and pasturage was the sole art by which the people were maintained. The like observation may be extended to Denmark and Sweden. No one ought to esteem the immense swarms of people which formerly came from the North, and overran all Europe, to be any objection to this opinion. Where a whole nation, or even half of it, remove their seat, it is easy to imagine what a prodigious multitude they must form, with what desperate valour they must make their attacks, and how the terror they strike into the invaded nations will make these magnify, in their imagination, both the courage and multitude of the invaders. Scotland is neither extensive nor populous, but were the half of its {p166} inhabitants to seek new seats they would form a colony as large as the Teutons and Cimbri, and would shake all Europe, supposing it in no better condition for defence than formerly.
Germany has surely at present twenty times more inhabitants than in ancient times, when they cultivated no ground, and each tribe valued itself on the extensive desolation which it spread around, as we learn from Cæsar, and Tacitus, and Strabo. A proof that the division into small republics will not alone render a nation populous, unless attended with the spirit of peace, order, and industry.
The barbarous condition of Britain in former times is well known, and the thinness of its inhabitants may easily be conjectured, both from their barbarity and from a circumstance mentioned by Herodian, that all Britain was marshy, even in Severus’s time, after the Romans had been fully settled in it above a whole century.
It is not easily imagined that the Gauls were anciently much more advanced in the arts of life than their northern neighbours, since they travelled to this island for their education in the mysteries of the religion and philosophy of the Druids.[94] I cannot therefore think that Gaul was then near so populous as France is at present.
Were we to believe, indeed, and join together the testimony of Appian and that of Diodorus Siculus, we must admit an incredible populousness in Gaul. The former historian says that there were 400 nations in that country; the latter affirms that the largest of the Gallic nations consisted of 200,000 men, besides women and children, and the least of 50,000. Calculating therefore at a medium, we must admit of near 200,000,000 of people in a country which we esteem populous at present, though supposed to contain little more than twenty.[95] Such {p167} calculations therefore by their extravagance lose all manner of authority. We may observe that that equality of property, to which the populousness of antiquity may be ascribed, had no place among the Gauls. Their intestine wars also, before Cæsar’s time, were almost perpetual. And Strabo observes that though all Gaul was cultivated, yet it was not cultivated with any skill or care, the genius of the inhabitants leading them less to arts than arms, till their slavery to Rome produced peace among themselves.
