Chimú Culture constructed 10 km wall to protect capital against El Niño events

Published

Archaeologists conducting a study of the Muralla La Cumbre, a 10 km wall in northern Peru, have concluded that the Chimú Culture constructed the wall to protect the capital of Chan Chan against El Niño events.

The Chimú culture emerged around AD 850-900 and controlled a territory encompassing 1,000 km (620 mi) of coastline from Piura in the north to Paramonga in the south.

The Kingdom was centred on Chan Chan, a large adobe city located at the mouth of the Moche Valley in an arid area of coastal desert. The city reached its peak during the 15th century AD, where it is estimated to have had a population of around 40,000 to 60,000 inhabitants.

The Chimú constructed the Muralla La Cumbre, a large trapezoidal stone wall during the 13th or 14th century AD, which runs from Cerro Cabras to Cerro Campana over a distance of 10 km.

Various theories for the purpose of the wall have been proposed, with the most prominent being as a territorial delimitation of the Chimú capital, to protect the city from Inca invasion, or as a ceremonial causeway.

Excavations led by archaeologist, Gabriel Prieto Burméster, Director of the Huanchaco (Pahuan) Archaeological Project, has suggested that the wall was instead built to protect Chan Chan from El Niño events.

El Niño events may have led to the demise of the Moche and other pre-Columbian Peruvian cultures. A recent study, titled “Global impact of the 1789-93 El Niño”, even suggests that a strong El Niño event caused poor crop yields in Europe, which in turn helped spark the French Revolution.

The researchers found an accumulation of almost two metres of sediment with multiple interstices of sand and mud which only occur on one side of the wall. There are 12 interstices detected, suggesting 12 climatic events.

A radio carbon analysis of roots found in one of the sediment layers has revealed a date of AD 1400-1450. This period coincides with a large sacrifice of 250 children and 40 warriors discovered near Chan Chan in 2019, which experts at the time suggest was to appease the gods for protection against natural catastrophes linked to El Niño events.

Revolutionary war barracks discovered at Colonial Williamsburg

Published

Archaeologists excavating at Colonial Williamsburg have discovered a barracks for soldiers of the Continental Army during the American War of Independence.

Colonial Williamsburg is a living-history museum that forms part of the historic district in the city of Williamsburg, Virginia.

Williamsburg was the capital of the Virginia colony from 1699 until 1779, founded by English settlers during the Second Anglo-Powhatan War (1622–1632).

Tensions with England mounted over fundamental civil and economic rights for the colonists, resulting in the American Revolution and the American War of Independence.

Archaeologists excavating next to the museum’s visitor’s centre uncovered foundations of a barracks that could accommodate up to 2,000 soldiers from the Continental Army and up to 100 horses.

“We have horseshoes,” said Jack Gary, Colonial Williamsburg executive director of archaeology. “We also have this object here which is a snaffle bit, so it’s part of a horse bit that goes in the mouth to control the horse. And this object here is part of a curry comb for brushing down the horse’s coat.”

Excavations have so far unearthed only a small part of the complex, but experts suggest that it covered roughly three to four acres.

The barracks were known from Eighteenth-century maps and other historical documents, but until now, the exact location of where it existed within the colony interior was unknown.

According to the historical sources, the barracks were built between 1776 and 1777, and were later destroyed by fire in 1781 by soldiers of the British Army under the command of General Cornwallis.

Excavations also uncovered mid-1700 chimney bases, ceramics, gun flint, coins, musket balls, military buckles, and items of decorative jewellery worn by high-ranking officers as cufflinks.

An interesting discovery are examples of lead shot with indications of tooth-marks, suggesting that the soldiers chewed on the lead shot because it tasted sweet.

Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought

Archaeologists have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought.

An analysis of the oldest archaeological sites on the island suggests that the first human occupation occurred between 14,257 and 13,182 years ago.

This analysis, published in the journal Proceedings of the National Academy of Sciences, used archaeological data, climate estimates, and demographic modelling.

The demographic modelling indicates that these early groups consisted of hundreds to thousands of people, who arrived in two to three main migration events over a period of only 100 years. Within just a few centuries, 11 generations – the population of Cypris had expanded to up 4,000 to 5000 inhabitants.

According to the study authors, these findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies. “This settlement pattern implies organised planning and the use of advanced watercraft,” says Professor Bradshaw.

The climate estimates suggest that these early settlers arrived at a time during an increase in temperature and precipitation, also enabling an increase in environmental productivity that could sustain large hunter-gather populations.

Dr Moutsiou, said: “It has been argued that human dispersal to and settlement of Cyprus and other eastern Mediterranean islands is attributed to demographic pressures on the mainland after abrupt climatic change saw coastal areas inundated by post-glacial sea-level rise, forcing farming populations to move to new areas out of necessity rather than choice.”

Our research, based on more archaeological evidence and advanced modelling techniques, changes that”, adds Dr Moutsiou.

The research – “Demographic models predict end-Pleistocene arrival and rapid expansion of pre-agropastoralist humans in Cyprus” by Corey Bradshaw, Christian Reepmeyer, Frédérik Saltré, Athos Agapiou, Vasiliki Kassianidou, Stella Demesticha, Zomenia Zomeni, Miltiadis Polidorou and Theodora Moutsiou – has been published in the Proceedings of the National Academy of Sciences of the USA.
