A prominent feature of the landscape is the Sierra de Malintzi, or Malinche, that is, "Lord of Marina," a name given to Cortes after his alliance with the "heroine of the conquest." The Sierra (originally Matlacuezatl), which rises grandly (more than 16,000 feet) above the plateau, takes a prominent place in Tlaxcaltecan mythology, owing to the peculiar shape of its summit, representing in rough outline the body of a native woman lying at full length in its grave and partly wrapped in its cerements. There are some woollen manufactures, centred chiefly in the capital, and also a few silver, copper, lead, and coal mines in the San Ambrosio and San Mateo ranges; but the state is essentially agricultural, yielding large annual crops of maize and wheat, the total produce being valued at over 1,000,000.
