So much is certain, that at an epoch the date of which it is impossible to fix, but which must have been remote, this race, cut off from all the world by the sea and the profoundest savagery, developed a civilization _sui generis_, to which the traditional reminiscences of the natives and a series of most remarkable ruins, discovered especially in Central America, bear witness. For it is in this southern district that we find the monumental ruins of Palenque, of Chiapa, of Uxmal, of Utatlan, and of other places, the list of which has again begun to receive additions in recent years. When the Spaniards conquered the New World, the centre of this civilization had shifted further north, to Mexico proper, to the city of Mexico, to Tezcuco and to Cholula. But the consciousness that the Mexican civilization was affiliated to that of the isthmic region had by no means been lost. It was a nation or race called Maya, the name of which seems to indicate that it considered itself indigenous, and the proper centre of which lay in Yucatan, that produced this American civilization--capable of organizing states and priesthoods, of rearing immense palaces, of carving stone in great perfection and with a true artistic sense, and of realizing a high degree of physical well-being. There is reason to believe, however, that this civilization, resembling in some respects that of ancient Canaan, had more refinement in its pursuit of material comfort than vigour in its morality. A certain effeminacy, and even the endemic practice of odious vices, appears to have early enervated it. When the Spaniards arrived in America, wars and devastating invasions had shattered the old and powerful monarchies of the central region and reduced the great monuments of antiquity to ruins, and that too so long ago that the natives themselves, while retaining a certain civilization, had lost all memory of the ancient cities and the ancient palaces that the Europeans rescued from oblivion. We may still see figured amongst the monuments of Mexico those beautiful ruins of Palenque, where stretches a superb gallery, vaulted with the broad ogives that recal the Moorish architecture of the Alhambra; while at Tehuantepec an immense temple has been discovered, hollowed out of a huge rock, like certain temples in India. The cultivation of maize was to this region what that of wheat was to Egypt and Mesopotamia, or of rice to India and China, the material condition, namely, of a precocious civilization. For, as has been remarked, the primitive civilizations could not be developed except where an abundant cereal raised man above immediate anxiety for his subsistence, and rescued him from the all-engrossing fatigues and the dangerous uncertainties of the hunter's life.
