Ancient mummy labels help to reconstruct climate of Roman Egypt

Published

on

A project funded by the Swiss National Science Foundation (SNSF) is using mummy labels to help reconstruct the climate of Roman Egypt.

Mummy labels are small labels made of wood, faience, or ivory, that were attached to mummies during the Ptolemaic and Roman periods.

The label would generally have an inscription written in Greek or demotic (and sometimes in hieratic or hieroglyphs) that named the deceased, their family, or a short prayer for the afterlife. The labels were used as a means to identify the deceased after the mummification process for when they were being transported to a necropolis for burial.

These small labels could even play the role of a cheap substitute for funerary stelae, as sometimes indicated by their shape and the fact that they could be identified as wy.t or στήλη “stela.”

As part of a new study, researchers are analysing the tree rings on the wooden labels in a process known as dendroclimatology. This reveals a wealth of climatic data, as tree rings are wider when conditions favour growth and are narrower when times are difficult during periods of drought.

The results of the study are published in the International Journal of Wood Culture, where the researchers analysed 300 labels and looked for matching sequences to give a broader view of what the climate was like in the areas of the eastern Mediterranean, in modern-day Lebanon, the Greek islands, or the mouth of the Nile during the period of Roman Egypt (30 BC – AD 641).

“That’s why mummy labels are ideal for our purposes”, explains François Blondel, an archaeologist at the University of Geneva. “Not only are there thousands of them in museums around the world, they’re made from lots of different tree species, such as pine, cypress, cedar and juniper”.

There are a few good years here and an unfortunate succession of droughts there, but the actual dates are still unclear, François Blondel explains. “We can’t yet assign a precise date to the rings and the events they record”.

The next step going forward will therefore be to locate these events in history. With luck, the scientists will find a datable specimen. Then, by looking for overlaps with other labels from the same tree species and region, they should be able to pinpoint the exact date. If not, they will have to resort to radiocarbon dating.

By combining several samples of wood taken along the rings of the same specimen, it is possible to statistically reduce dating uncertainty – to virtually zero in the best-case scenario. The scientists still have to find the right specimens and, above all, obtain permission from museums for invasive radiocarbon analysis.

Archaeologists find traces of violent history on Anglo-Scottish border

Published

Archaeologists from the Border Reivers Archaeology Unit have uncovered traces of the violent history along the Anglo-Scottish border.

Excavations at the Swinton Kirk parish church in the village of Swinton, located north of the Scottish border, have uncovered human remains consisting of 124 bone fragments that show signs of multiple injuries at the time of death.

An anthropological study has identified up to five individuals among the fragments, two of which are adults, while the other three are children/young adults.

The church, which dates from 1100 (with significant alterations in 1593), was used as a refuge during the Anglo-Scottish Wars and the systemic raiding by the Reivers.

The Reivers were English and Scottish raiders that attacked settlements on both sides of the border land between the late 13th century to the beginning of the 17th century.

The Wardens of the Marches governed the Marcher law, which granted individuals who had been raided the legal authority to retaliate with a raid of their own within six days to reclaim their property.

Swinton was attacked by English forces at least four times in the 15th to 16th centuries, evidenced by the remains of a defensive earthwork bank around the parish church.

Among the bone fragments, osteoarchaeologists have found two fragments from the lower leg bone that has indications of sharp force trauma from a blade. According to the experts, the trauma occurred peri-mortem (around the time of death).

An archaeologist from the Border Reivers Archaeology Unit said: “Living human bone has a completely different consistency and texture from dead bone. The living bone is more like a very hard dense wax or wood and is not as brittle as dead bone, it breaks and cuts in a completely different way.”

One of the shin bones uncovered also has slashing marks, while a thigh bone has teeth marks likely from a large canid (dog or wolf).

Inside the tomb of the First Emperor

Published

By

The tomb of the First Emperor, also known as the Mausoleum of the First Qin Emperor, is the burial complex and mausoleum of Qin Shi Huang, the founder of the Qin Dynasty and the first emperor of a unified China.

According to the Records of the Grand Historian by Sima Qian (a historian from the Han period), Qin Shi Huang was born in 259 BC in Handan, the capital of Zhao.

He was given the name of Ying Zheng or Zhao Zheng – Zheng being his month of birth “Zhengyue”, the first month of the Chinese lunar calendar.

Around 246 – 247 BC, the 13-year-old Ying Zheng succeeded his father to the throne of Qin and reigned for 36 years as Qin Shi Huang until his death in 210 BC.

Qin Shi Huang’s reign brought about the unification of China and an end to the Warring States period in 221 BC. He constructed a series of walls to connect fortifications along the empire’s northern frontier (the precursor to the Great Wall of China) and built a national road system and the Lingqu Canal.

Although some historians see Qin Shi Huang’s rule as one of tyranny, he did enact several major economic and political reforms to standardise the Chinese states incorporated into his Empire and worked to completely abolish the feudal system of loose alliances and federations.

During his life, Qin Shi Huang became obsessed with immortality and sought the elixir of life. He sent ships in search of Penglai mountain on an inhabited island, where an ancient magician known as Anqi Sheng was said to reside. Qin mythology believed that immortals resided on the mountain and knew the secret to everlasting life.

It was this obsession with immortality that would be Qin Shi Huang’s downfall, as many historians propose that he died from prolonged poisoning due to regular consumption of an elixir containing mercury. Mercury exposure would undoubtedly cause a decline in function of the central nervous system and result in severe brain and liver damage.

Qin Shi Huang was buried in the Mausoleum of the First Qin Emperor, a large complex commissioned when he first became emperor. The mausoleum is located in present-day Lintong District in the city of Xi’an, and was constructed over 38 years using 700,000 workmen (based on historical text).

The structure of the mausoleum is situated beneath a 76-metre-tall hillock (mound) shaped like a truncated pyramid, however, due to soil erosion the pyramid now stands at 47 metres tall. The base of the pyramid measures 515 x 485 metres and covers an area of just under one square mile.

Excavations around the complex have discovered around 7,000 (estimates suggest up to 8,000) statues of terracotta warriors, horses, officials, acrobats, strongmen, and musicians, and around 100 wooden battle chariots placed to serve the emperor in his afterlife.

Archaeologists have steered clear of excavating the tomb beneath the hillock due to concerns of the irreparable damage that would be caused to the structure, and the accelerated degradation of the tomb contents when exposed to contaminants such as air pollutants, temperature oscillations, changes in humidity, bacteria and fungus.

This is evidenced with the terracotta warriors, as when they were first excavated, the painted surface present on some examples began to flake and fade within seconds of exposure to the dry air of Xi’an’s climate.

What is known about the tomb interior comes again from the Records of the Grand Historian by Sima Qian, who describes how workmen constructed palaces and scenic towers for a hundred officials within the interior of the hillock. They poured bronze to cast the emperors outer coffin and filled the tomb with rare artefacts and treasures from across China.

Using non-invasive techniques such as geo radar and gravimetre investigations, archaeologists have determined that the “palace” measures 140 × 110 × 30 m3, while the central coffin chamber measures 80 × 50 × 15 m3.

Most interestingly, is Sima Qian’s account of Mercury being used in the tomb to simulate the hundred rivers, the Yangtze, Yellow River, and the great sea, which sat below a representation of the heavenly constellations.

In 2016, a study using lidar mapping was conducted around the mausoleum to detect traces of mercury concentrations. The study found elevated concentrations up to 27 ng/m3, significantly higher than the typical general pollutant level in the area which was found to be around 5–10 ng/m3.

The State Administration of Cultural Heritage (SACH) continues to follow a process of research and evaluations to develop a protection plan before any long-term excavations can take place in the Mausoleum of the First Qin Emperor.
