Describes the work of archaeologists who have uncovered the artifacts of the ancient Maya.

As Europe endured its Dark Ages, the Maya mapped the heavens and mastered mathematics. They constructed vast cities in jungle landscapes, leaving legacies in stone at places like Palenque and Uxmal. In overgrown sites, archaeologists now piece together this civilization with the aid of satellite technology. Modern-day experts provide windows into the Mayan world by interpreting ancient messages, inscribed for future generations. National Geographic supports K-12 educators with ELA Common Core Resources.

The #1 New York Times and Wall Street Journal bestseller, named one of the best books of the year by The Boston Globe and National Geographic: acclaimed journalist Douglas Preston takes readers on a true adventure deep into the Honduran rainforest in this riveting narrative about the discovery of a lost civilization -- culminating in a stunning medical mystery. Since the days of conquistador Hernán Cortés, rumors have circulated about a lost city of immense wealth hidden somewhere in the Honduran interior, called the White City or the Lost City of the Monkey God. Indigenous tribes speak of ancestors who fled there to escape the Spanish invaders, and they warn that anyone who enters this sacred city will fall ill and die. In 1940, swashbuckling journalist Theodore Morde returned from the rainforest with hundreds of artifacts and an electrifying story of having found the Lost City of the Monkey God-but then committed suicide without revealing its location. Three quarters of a century later, bestselling author Doug Preston joined a team of scientists on a groundbreaking new quest. In 2012 he climbed aboard a rickety, single-engine plane carrying the machine that would change everything: lidar, a highly advanced, classified technology that could map the terrain under the densest rainforest canopy. In an unexplored valley ringed by steep mountains, that flight revealed the unmistakable image of a sprawling metropolis, tantalizing evidence of not just an undiscovered city but an enigmatic, lost civilization. Venturing into this raw, treacherous, but breathtakingly beautiful wilderness to confirm the discovery, Preston and the team battled torrential rains, quickmud, disease-carrying insects, jaguars, and deadly snakes. But it wasn't until they returned that tragedy struck: Preston and others found they had contracted in the ruins a horrifying, sometimes lethal-and incurable-disease. Suspenseful and shocking, filled with colorful history, hair-raising adventure, and dramatic twists of fortune, THE LOST CITY OF THE MONKEY GOD is the absolutely true, eyewitness account of one of the great discoveries of the twenty-first century.

Describes the work of archaeologists who have uncovered the artifacts of ancient India.

When the Maya kings of Tikal dedicated their first carved monuments in the third century A.D., inaugurating the Classic period of Maya history that lasted for six centuries and saw the rise of such famous cities as Palenque, Copan and Yaxchilan, Maya civilization was already nearly a millennium old. Its first cities, such as Nakbe and El Mirador, had some of the largest temples ever raised in Prehispanic America, while others such as Cival showed even earlier evidence of complex rituals. The reality of this Preclassic Maya civilization has been documented by scholars over the past three decades: what had been seen as an age of simple village farming, belatedly responding to the stimulus of more advanced peoples in highland Mesoamerica, is now know to have been the period when the Maya made themselves into one of the New World's most innovative societies. This book discusses the most recent advances in our knowledge of the Preclassic Maya and the emergence of their rainforest civilization, with new data on settlement, political organization, architecture, iconography and epigraphy supporting a contemporary theoretical perspective that challenges prior assumptions.
