Maya engineers constructed numerous bridges with spans up to 50 feet long with timber beams. This figure shows a cross section of the Classic Period Maya bridge over the Pusilha River. Maya short span bridges crossed streams, canals and moats in urban environments.
Though foreign invaders were disappointed by the region’s relative lack of silver and gold , the Maya took advantage of the area’s many natural resources, including limestone (for construction), the volcanic rock obsidian (for tools and weapons) and salt .
These technological achievements include the fabrication of tools that are harder than iron; the invention of high strength durable materials of construction including the fabrication of hydraulic cement for producing cast-in-place concrete; the development of the Maya arch as a structural mechanism to create multi-
The vast Inca road network relied on about 200 rope bridges to traverse the steep valleys and canyons of the Andes. Constructed from grass and other natural materials, the swaying bridges were especially suited to the Incas as they never invented wheeled transport.
Chichen Itza was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archaeological site is located in Tinúm Municipality, Yucatán State, Mexico.
The basic idea—based on centuries- old Inca building techniques—is that the grass is woven into rope , which is then woven into larger cords, which is then woven into the cables that make up the basic formation of the bridge .
The Inca Empire built a huge civilization in the Andes mountains of South America. Some of their most impressive inventions were roads and bridges, including suspension bridges, and their communication system called quipu, a system of strings and knots that recorded information.
A simple suspension bridge (also rope bridge , swing bridge (in New Zealand), suspended bridge , hanging bridge and catenary bridge ) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end.
After assembling a record-setting 154 radiocarbon dates, the researchers have been able to develop a highly precise chronology that illuminates the patterns that led up to the two collapses that the Maya civilization experienced: the Preclassic collapse, in the second century A.D., and the more well-known Classic
Scholars have suggested a number of potential reasons for the downfall of Maya civilization in the southern lowlands, including overpopulation, environmental degradation, warfare, shifting trade routes and extended drought. It’s likely that a complex combination of factors was behind the collapse.
The Maya have lived in Central America for many centuries. They are one of the many Precolumbian native peoples of Mesoamerica . In the past and today they occupy Guatemala, adjacent portions of Chiapas and Tabasco, the whole of the Yucatan Peninsula, Belize, and the western edges of Honduras and Salvador.
The Mayan religion was Polytheist, and they worshiped more than 165 Gods. The Gods were human-like. The Gods were born, grew up and died. Gods would do other human like activity that was deemed acceptable behavior.
The Classic Maya in particular developed some of the most accurate pre- telescope astronomy in the world, aided by their fully developed writing system and their positional numeral system, both of which are fully indigenous to Mesoamerica.
