1. Chapter 10 Remaking the World: Environmental Frontiers before 1000 C.E.

2. Review Questions HOW DID geography influence the transmission of culture in sub-Saharan Africa and the Americas? WHAT WERE the environmental consequences of the Islamic conquests in Africa and Eurasia? WHERE DID Christendom expand in the eighth and ninth centuries? HOW DID Japan, China, and the states of southeast Asia seek to stimulate economic growth? HOW DID Pacific islanders succeed in colonizing the Pacific? HOW WIDESPREAD during the history of this period was ecological experiment?

4. Figure of a sacred king. The Oni, or king, of lle-lfe, excavated at lta Yemoo, Nigeria in 1957, 1000-1100 C.E. The king is shown draped in beads, a symbol of royalty.

7. Nazca lines. The Nazca made the vast images for which they are famous by scraping the surface of the desert in Peru to reveal the bare rock underneath. But why did they do it? Vivid, intricate designs, such as this monkey, were too big to be fully visible except from the air. The people who made them can only have experienced them by walking the pathways the patterns made. The straight lines that accompany the images may have served as maps, perhaps indicating underground irrigation channels, but the pictures remain a mystery.

8. Mayan kings. The legitimacy that royal ancestry conferred was an important part of Maya kingship— especially when things were going badly. Yax Pasaj, who became king of Copán in 763, when he was still a small boy, ruled in a time of economic decline and political unrest. This may be why he had himself depicted in the company of all Copán’s previous rulers, seated as if in conference around a small stone platform.

9. Royal Bloodletting. The reign of Itzamnaaj B’alam (“Shield Jaguar”) II of Yaxchilián (681-742), in what is today Mexico, produced some of the finest stone reliefs in which Maya rulers commemorated their performance of important rituals. The most common ritual was royal bloodletting, which was intended to provoke visions. During these bloodlettings, kings communicated with ancestor’s or gods.

10. The Dresden codex. The Maya almanac known as the Dresden Codex contains a wealth of data on agriculture, divination, and religion. But its most remarkable contents are the detailed astronomical observations and predictions,including the table recording the cycle of Venus, one page of which is shown here. The red bars and dots at bottom right are numbers, adding up to 584—the average number of days between the dates on which Venus rises with the sun. Such dates were favorable for war and sometimes foretold drought and death. The gods depicted represent from top to bottom, the Morning Star, Venus as bringer of war, and Venus demanding sacrifice.

13. Watermill. Increased agricultural output caused demand for more and bigger mills to grind grain. Most have not survived, but a fine example of medieval watermill technology, pictured here, is on the Orontes River at Hama, Syria. Water wheels on this scale also hoisted water from riverbeds to aqueducts and irrigation channels.

19. The Grand Canal. China’s ancient canals are still useful to commerce. Here, long lines of barges sail the Grand Canal, an artificial waterway that was first built in the seventh century C.E.

21. The temple of Borobodur on the Indonesian island of Java began to receive pilgrims in the early 800s. Visitors, emerging from the dense tropical forest that surrounded the site, would ascend through four galleries, where stories of virtuous Buddhists were carved in relief eventually reaching the realm of Enlightenment— the circular platform, guarded by statues of Bodhisattvas.

26. Today’s Question Do we have any place left to go? Consider The voyages of the Polynesians were amazing feats of exploration and settlement, opening up a whole new world for human communities. They also filled the last great hole in human habitation outside of Antarctica.
