laying out a city, would take these things into consideration; much more should he who examines the whole earth: for such things in a peculiar manner belong to him. In small distances a little deviation north or south does not signify, but when it is the whole circle of the earth, the north extends to the furthest confines of Scythia,45 or Keltica,46 and the south to the extremities of Ethiopia: there is a wide difference here. The case is the same should we inhabit India or Spain, one in the east, the other far west, and, as we are aware, the antipodes47 to each other.
14. The [motions] of the sun and stars, and the centripetal force meet us on the very threshold of such subjects, and compel us to the study of astronomy, and the observation of such phenomena as each of us may notice; in which too, very considerable differences appear, according to the various points of observation. How could any one undertake to write accurately and with propriety on the differences of the various parts of the earth, who was ignorant of these matters? and although, if the undertaking were of a popular character, it might not be advisable to enter thoroughly into detail, still we should endeavour to include every thing which could be comprehended by the general reader.
15. He who has thus elevated his mind, will he be satisfied with any thing less than the whole world? If in his anxiety accurately to portray the inhabited earth, he has dared to survey heaven, and make use thereof for purposes of instruction, would it not seem childish were he to refrain from examining the whole earth, of which the inhabited is but a part, its size, its features, and its position in the universe; whether other portions are inhabited besides those on which we dwell, and if so, their amount? What is the extent of the regions not peopled? what their peculiarities, and the cause of their remaining as they are? Thus it appears that the knowledge of geography is connected with meteorology48 and geometry, that it unites the things of earth to the things of heaven, as though they were nearly allied, and not separated.
“As far as heaven from earth.”49
16. To the various subjects which it embraces let us add natural history, or the history of the animals, plants, and other different productions of the earth and sea, whether serviceable or useless, and my original statement will, I think, carry perfect conviction with it.
That he who should undertake this work would be a benefactor to mankind, reason and the voice of antiquity agree. The poets feign that they were the wisest heroes who travelled and wandered most in foreign climes: and to be familiar with many countries, and the disposition of the inhabitants, is, according to them, of vast importance. Nestor prides himself on having associated with the Lapithæ,50 to whom he went, “having been invited thither from the Apian51 land afar.”
So does Menelaus:—
“Cyprus, Phœnicia, Sidon, and the shores
Of Egypt, roaming without hope I reach’d;
In distant Ethiopia thence arrived,
And Libya, where the lambs their foreheads show
With budding horns defended soon as yean’d.”52
Adding as a peculiarity of the country,
“There thrice within the year the flocks produce.”53
And of Egypt:—“Where the sustaining earth is most prolific.”54 And Thebes,
“the city with an hundred gates,
Whence twenty thousand chariots rush to war.”55
Such information greatly enlarges our sphere of knowledge, by informing us of the nature of the country, its botanical and zoological peculiarities. To these should be added its marine history; for we are in a certain sense amphibious, not exclusively connected with the land, but with the sea as well. Hercules, on account of his vast experience and observation, was described as “skilled in mighty works.”56
All that we have previously stated is confirmed both by the testimony of antiquity and by reason. One consideration however appears to bear in a peculiar manner on the case in point; viz. the importance of geography in a political view. For the sea and the earth in which we dwell furnish theatres for action; limited, for limited actions; vast, for grander deeds; but that which contains them all, and is the scene of the greatest undertakings, constitutes what we term the habitable earth; and they are the greatest generals who, subduing nations and kingdoms under one sceptre, and one political administration, have acquired dominion over land and sea. It is clear then, that geography is essential to all the transactions of the statesman, informing us, as it does, of the position of the continents, seas, and oceans of the whole habitable earth. Information of especial interest to those who are concerned to know the exact truth of such particulars, and whether the places have been explored or not: for government will certainly be better administered where the size and position of the country, its own peculiarities, and those of the surrounding districts, are understood. Forasmuch as there are many sovereigns who rule in different regions, and some stretch their dominion over others’ territories, and undertake the government of different nations and kingdoms, and thus enlarge the extent of their dominion, it is not possible that either themselves, nor yet writers on geography, should be equally acquainted with the whole, but to both there is a great deal more or less known. Indeed, were the whole earth under one government and one administration, it is hardly possible that we should be informed of every locality in an equal degree; for even then we should be most acquainted with the places nearest us: and after all, it is better that we should have a more perfect description of these, since, on account of their proximity, there is greater need for it. We see there is no reason to be surprised that there should be one chorographer57 for the Indians, another for the Ethiopians, and a third for the Greeks and Romans. What use would it be to the Indians if a geographer should thus describe Bœotia to them, in the words of Homer:—
“The dwellers on the rocks
Of Aulis follow’d, with the hardy clans
Of Hyria, Schœnus, Scolus.”58
To us this is of value, while to be acquainted with the Indies and their various territorial divisions would be useless, as it could lead to no advantage, which is the only criterion of the worth of such knowledge.
17. Even if we descend to the consideration of such trivial matters as hunting, the case is still the same; for he will be most successful in the chase who is acquainted with the size and nature of the wood, and one familiar with the locality will be the most competent to superintend an encampment, an ambush, or a march. But it is in great undertakings that the truth shines out in all its brilliancy, for here, while the success resulting from knowledge is grand, the consequences of ignorance are disastrous. The fleet of Agamemnon, for instance, ravaging Mysia, as if it had been the Trojan territory, was compelled to a shameful retreat. Likewise the Persians and Libyans,59 supposing certain straits to be impassable, were very near falling into great perils, and have left behind them memorials of their ignorance; the former a monument to Salganeus on the Euripus, near Chalcis, whom the Persians slew, for, as they thought, falsely conducting their fleet from the Gulf of Malea60 to the Euripus; and the latter to the memory of Pelorus, who was executed on a like occasion. At the time of the expedition of Xerxes, the coasts of Greece were covered with wrecks, and the emigrations from Æolia and Ionia furnish numerous instances of the same calamity. On the other hand, matters have come to a prosperous termination, when judiciously directed by a knowledge of the locality. Thus it was at the pass of
