The shaded circles represent the various continents; the outer circle represents the actual extent of coast-line. The blank space between the two concentric circles represents graphically the difference between the smallest possible or geometrical contour of a country having the area of the respective continents, and the actual contour as exhibited in the existing coast-lines. Europe, being in reality only a peninsula of Asia, hardly admits of this comparison.
The islands of Europe must be looked upon as dependencies of that continent, for most of them are separated from it only by shallow seas. Candia and the islands scattered broadcast over the Ægean Sea, the Archipelagos of the Ionian Sea, and of Dalmatia, Sicily, Corsica and Sardinia, Elba, and the Baleares, are in reality but prolongations, or maritime out-stations, of neighbouring peninsulas. To the islands of Sealand and Fyen, at the entrance to the Baltic, Denmark owes {15} most of her commercial and political importance. Great Britain and Ireland, which actually formed a portion of the European continent in a past age, cannot be looked upon otherwise than as dependencies of it, although the isthmus which once joined them has been destroyed by the waters of the ocean. England has actually become the grand commercial emporium of Europe, and plays now the same part in the world’s commerce that Greece once played in that of the more restricted world of the Mediterranean.
It is a remarkable fact that each of the European peninsulas should have enjoyed in turn a period of commercial preponderance. Greece, the “most noble individuality of the world of the ancients,” came first, and when at the height of her power governed the Mediterranean, which at that time meant nearly the whole universe. During the Middle Ages Amalfi, Genoa, and Venice became the commercial agents between Europe and the Indies. The discovery of a passage round the Cape and of America diverted the world’s commerce to Cadiz, Seville, and Lisbon, on the Iberian peninsula. Subsequently the merchants of the small Dutch Republic seized a portion of the heritage of Spain and Portugal, and the wealth of the entire world was floated into the harbours of their sea-bound islands and peninsulas. In our own days Great Britain, thanks to its favourable geographical position, in the very centre of great continental masses, and the energy of its people, has become the great mart of the world. London, the most populous city of the world, is also the great centre of attraction for the treasures of mankind; but there can be no doubt that sooner or later it will be supplanted, in consequence of the opening of new commercial high-roads, and changes in the political preponderance of nations. Perhaps some city of the United States will take the place of London in a future age, and thus the American belief in the westward march of civilisation will be verified; or we may possibly return to the East, and convert Constantinople or Cairo into the world’s emporium and centre of intercourse.
But, whatever may happen in the future, the great changes which have taken place in the relative importance of the peninsulas and islands of Europe in the short span of twenty centuries, sufficiently prove that geographical features exercise a varying influence at different epochs. That which at one time was looked upon as a great natural advantage may become, in course of time, a serious disadvantage. Thus the numerous inlets and gulfs enclosed by mountain chains, which favoured the rise of the cities of Greece, and gave to Athens the dominion of the Mediterranean, now constitute as many obstacles to their connection with the existing system of European communications. That which in former times constituted the strength of the country has become its weakness. In primitive times, before man ventured upon the seas, these bays and gulfs formed insurmountable obstacles to the migration of nations; at a later date, when the art of navigation had been acquired, they became commercial high-roads, and were favourable to the development of civilisation; and at the present time they are again obstacles in the way of our road-builders and railway engineers. {16}
V.—CLIMATE.
The influence exercised by the relief of the land and the configuration of the coasts varies in different ages, but that of climate is permanent. In this respect Europe is the most favoured region of the earth, for during a cycle of unknown length it has enjoyed a climate at once the most temperate, the most equable, and the most healthy of all continents.
Owing to the inland seas which penetrate far into the land, the whole of Europe is exposed to the modifying influence of the ocean. With the exception of Central Russia, no part of Europe is more than 400 miles from the sea, and, as most of the mountains slope from the centre of the continent towards its circumference, the influence of the sea breezes is felt throughout. And thus continental Europe, in spite of its great extent, enjoys the advantages of an insular climate throughout, the winds passing over the ocean moderating the heat of summer and tempering the cold of winter.
