The Mayan culture was made possible by the agricultural conquest of the rich lowlands where the exuberance of nature can only be held in check by organized effort. On the highlands the preparation of the land is comparatively easy, owing to scanty natural vegetation and a control vested in irrigation. On the lowlands, however, great trees have to be felled and fast-growing bushes kept down by untiring energy. But when nature is truly tamed she returns recompense many fold to the daring farmer. Moreover, there is reason to believe that the removal of the forest cover over large areas affects favorably the conditions of life which under a canopy of leaves are hard indeed.

The principal crops of the Mayas were probably much the same as on the highlands, with maize as the great staple. Varieties favorable to a humid environment had doubtless been developed from the highland stock by selective breeding as agriculture worked its way down into the lowlands. Archaic art appears along the edges of the Mayan Area in the state of Vera Cruz, Mexico, and in the Uloa Valley, Honduras. In both these regions are also found clay figurines that mark the transition in style between the archaic and the Mayan, as well as finished examples of the latter. There can be no doubt, then, that the archaic art of Mexico marks an earlier horizon than the Mayan. Whether or not it was once laid entirely across the Mayan Area cannot be decided on present data but it seems unlikely. We have already seen that this first art was distributed primarily across arid and open territory.
With their calendarial system already in working order the Mayas appear on the threshold of history 600 years before the Christian Era, according to a correlation with European chronology that will be explained later. The first great cities were Tikal in northern Guatemala and Copan in western Honduras, both of which had a long and glorious existence. Many others sprang into prominence at a somewhat later date; for example, Palenque, Yaxchilan or Menché, Piedras Negras, Seibal, Naranjo, and Quirigua. The most brilliant period was from 300 to 600 A. D., after which all these cities appear to have been abandoned to the forest that soon closed over them. The population moved to northern Yucatan, where it no longer reacted strongly upon the other nations of Central America and where it enjoyed a second period of brilliancy several hundred years later.
