The various arts of civilization kept pace with increasing wealth and public prosperity; at least, these arts were cultivated to the same limited extent, apparently, as among the other people of Anahuac. The Tlascalan tongue, says the national historian, simple as beseemed that of a mountain region, was rough compared with the polished Tezcucan or the popular Aztec dialect, and, therefore, not so well fitted for composition. But the Tlascalans made like proficiency with the kindred nations in the rudiments of science. Their calendar was formed on the same plan. Their religion, their architecture, many of their laws and social usages, were the same, arguing a common origin for all. Their tutelary deity was the same ferocious war-god as that of the Aztecs, though with a different name; their temples, in like manner, were drenched with the blood of human victims, and their boards groaned with the same cannibal repasts.[110] Though not ambitious of foreign conquest, the prosperity of the Tlascalans, in time, excited the jealousy of their neighbors, and especially of the opulent state of Cholula. Frequent hostilities rose between them, in which the advantage was almost always on the side of the former. A still more formidable foe appeared in later days in the Aztecs, who could ill brook the independence of Tlascala when the surrounding nations had acknowledged, one after another, their influence or their empire. Under the ambitious Axayacatl, they demanded of the Tlascalans the same tribute and obedience rendered by other people of the country. If it were refused, the Aztecs would raze their cities to their foundations, and deliver the land to their enemies. To this imperious summons, the little republic proudly replied, “Neither they nor their ancestors had ever paid tribute or homage to a foreign power, and never would pay it. If their country was invaded, they knew how to defend it, and would pour out their blood as freely in defence of their freedom now as their fathers did of yore, when they routed the Aztecs on the plains of Poyauhtlan!”[111] This resolute answer brought on them the forces of the monarchy. A pitched battle followed, and the sturdy republicans were victorious. From this period, hostilities between the two nations continued with more or less activity, but with unsparing ferocity. Every captive was mercilessly sacrificed. The children were trained from the cradle to deadly hatred against the Mexicans; and, even in the brief intervals of war, none of those intermarriages took place between the people of the respective countries, which knit together in social bonds most of the other kindred races of Anahuac.
