Ancient Civilizations of Mexico and Central America

Introduction

Geography and Natural Environment

Unfortunately the terms “Mexico and Central America” are not mutually exclusive. Central America is a natural division comprised between the Isthmus of Tehuantepec and the Isthmus of Panama. Mexico is a political division that includes several states in Central America, namely, Chiapas, Tabasco, Campeche, Yucatan, and the territory of Quintana Roo. The ancient high cultures of Mexico hardly extended as far north as the Tropic of Cancer and the region beyond this is of slight interest to us. Positions south of Mexico will often be referred to the areas of the modern political units although these have no immediate relation to pre-Spanish conditions. These political units are: Guatemala, British Honduras, Honduras, Salvador, Nicaragua, and Costa Rica.

Although lying within the tropics, the territory extending from the Isthmus of Panama to Central Mexico exhibits great extremes of climate and topography and hence of plant and animal life. The year is everywhere divided into a wet and a dry season but the relative duration of each depends upon land form and altitude. The coast of the Pacific is considerably drier than that of the Atlantic. Three climatic zones are generally recognized, namely, the Tierra Caliente (Hot Land), Tierra Templada (Temperate Land), and Tierra Fria (Cold Land), and in some regions each of these has an arid and a humid strip. The change from luxuriant forests to open thorny deserts is often very sudden. On the high plateau or Tierra Fria the natural warmth of the latitude is largely overcome by the altitude. In the Valley of Mexico snow falls only at rare intervals, yet chilling winds are common in the winter. Much of the plateau from Mexico south into Guatemala is open farming land well suited to the raising of maize and wheat where water is sufficient. The shoulders of the mountains bear forests of pine and oak while the highest peaks are crowned with perpetual snow.

A description of the mountains, rivers, and lakes will help towards an understanding of the problems that are before us. The broad plateau, crossed by irregular ranges of mountains, that occupies the states of New Mexico and Arizona continues far south into Mexico. On the western rim the Sierra Madre lifts a great pine-covered barrier, beyond which the land drops off quickly into the hot fringe of coastal plain bordering the Pacific Ocean and the Gulf of California. The highest mountains of the western Sierra Madre are El Nevado and Colima, the first a snowy peak 14,370 feet high and the second an active volcano 12,278 feet high. On the eastern rim of the central plateau the second Sierra Madre is less continuous but it culminates in the loftiest peak of all Mexico—the wonderful cone of Orizaba. This mountain rises from the tropical jungles well into the region of perpetual snow and attains an elevation of 18,314 feet above the sea. Its name in Aztecan is Citlaltepetl, which means Star Mountain. Two other famous peaks of Mexico are Popocatepetl and Iztaccihuatl, both names being pure Aztecan. The first means Smoking Mountain and the second White Woman. These volcanic crests rise into the snowy zone from the table-land which is itself about 8,000 feet above the sea.
