On a clear day in September a couple hiking along a high ridge in the Alps came upon a corpse melting out of the ice. When they returned to the mountain hut where they were staying, they alerted the authorities, who assumed the body was one of the missing climbers lost every year in the crevasses that crisscross the glaciers of the region. But after the remains were delivered to nearby Innsbruck, Austria, Konrad Spindler, an archaeologist from the university there, ascertained that the corpse was prehistoric. The victim, a male, had died several thousand years ago. Spindler and other scientists deduced that his body and belongings had been preserved in the ice until a fall of dust from the Sahara and an unusually warm spell combined to melt the ice, exposing the mans head, back and shoulders. No well-preserved bodies had ever been found in Europe from this period: the Neolithic, or New Stone Age. The Iceman is much older than the Iron Age men from the Danish peat bogs and older even than the Egyptian royal mummies. Almost as astounding was the presence of a complete set of clothes and a variety of gear. In the ensuing excitement over the discovery, the press and researchers offered many speculations about the ancient man. Spindler hypothesized an elaborate disaster theory.
Carbon dating: A window to the world
Producing an accurate age of these treasures is a key step for archaeologists, made possible through carbon dating, a process of dating organic material as far back as 60, years using nuclear technology. The mummified corpse was partly entombed in the ice and thought at first to be a fallen mountaineer or Italian soldier from one of the world wars. The ability to carbon date organic objects was first discovered in by Willard Libby , a professor of chemistry at the University of Chicago.
He determined that carbon, a radioactive isotope of carbon naturally found in the atmosphere, was absorbed by green plants and the animals that ate them. Libby correctly theorized that if the amount of carbon in an object could be detected, its age could be known by calculating the half-life about 5, years or rate of decay of the isotope, a process that begins when a living organism dies.
Oldest blood sample ever retrieved sheds new light on Ötzi’s death and may help improve understanding of blood aging.
One image of Otzi The Iceman is the name given to the mummified body of a was found in near a glacier near the border of Italy and Austria. He is the best-preserved prehistoric man ever discovered with his own equipment and clothing. Most ancient human remains are found in burial chambers with carefully selected objected rather than what they use in everyday life. Some have called the discovery of 5,year-old Otzi one of the most spectacular archaeological discoveries of the 20th century.
He is oldest intact human ever found. With the exception of missing toenails, all but one fingernail and an outer layer of skin the Iceman is otherwise perfectly reserved. His body and the tools and clothes found with him have given great insight into a people and age of which little is known in details never preciously imagined.

Otzi the Iceman
A perfect occasion for history lovers to look back on an eventful time full of sensations, findings and new insights. The mummy was freed with ski poles and pneumatic hammers as everyone thought it was a mountain accident victim. After precise surveying works the experts found out that the rock cave was already on the South Tyrolean territory. Housing and hunting tools are on display as well.
An arrow head was stuck in the left shoulder of the glacier mummy dating back to the Copper Age. The contents of his stomach were meat, fat and varied plant tissues — mostly fruit skins and seed coats of grain.
On the 19th of September finally, his body was discovered by accident. The wet mummy could be dated back to approx. The world-oldest mummy, however – embalmed by a person – is the body of a child which age is estimated at 7, years. It was found in the Atacama desert. Both countries – Austria and Italy – claimed to be the owners of the Hauslabjoch Mummy. Experts from all over the world examined his tissue, bones and organs to learn more about his state of health, furthermore his equipment and tattoos.
In , X-rays revealed the cause of death: The Iceman died from an injury caused by an arrow. Every visitor can take a look into the special cooling chamber which features the exact conditions of the eternal ice which preserved the world-famous glacier mummy for so long.
DNA Analysis Reveals What Ötzi the Iceman Wore to His Grave
Radiocarbon-dated to bce , the body is that of a man aged 25 to 35 who had been about 1. The small rocky hollow in which he lay down to die was soon covered and protected by glacial ice that happened to be melting 5, years later when his body was discovered by modern humans. It was at first believed that the Iceman was free of diseases, but in researchers discovered that his body had been infested with whipworm and that he had suffered from arthritis; neither of these conditions contributed to his death.
He also at one time had broken his nose and several ribs. His few remaining scalp hairs provide the earliest archaeological evidence of haircutting, and short blue lines on his skin lower spine, left leg, and right ankle have been variously interpreted as the earliest known tattoos or as scars remaining from a Neolithic therapeutic procedure.
The Iceman was later nicknamed “Ötzi”, after the mountain range where he was found. Two days after the first discovery, Hans Kammerlander and Reinhold.
The hand axe found with the body of the Alpine Iceman is one of the rare copper objects that is firmly dated to the early Copper Age because of the radiocarbon dating of the axe wooden shaft. Here we report the measurement of the lead isotope ratios of the copper blade. The results unambiguously indicate that the source of the metal is the ore-rich area of Southern Tuscany, despite ample evidence that Alpine copper ore sources were known and exploited at the time. The experimental results are discussed within the framework of all the available coeval archaeometallurgical data in Central-Southern Europe: they show that the Alps were a neat cultural barrier separating distinct metal circuits.
The direct evidence of raw metal or object movement between Central Italy and the Alps is surprising and provides a new perspective on long-distance relocation of goods and relationships between the early Copper Age cultures in the area. The result is in line with the recent investigations re-evaluating the timing and extent of copper production in Central Italy in the 4 th millennium BC.

Over two decades of scientific analyses on the mummy and related objects have provided unprecedented knowledge on ancestry, diet, tools, lifestyle, health and attire [ 3 — 9 ] of humans living in a relatively unexplored period of European prehistory.
Recently a number of scientific investigations finally addressed the archaeological issues related to the inorganic tools and implements found with the body, especially the copper blade Fig 1 , which is the oldest prehistoric metal blade found complete of the ropes and wooden handle in the world [ 11 ]. The microsample here analyzed was extracted from the major cavity.
Iceman research milestones
Through imaging techniques, we know about degeneration in his lumbar spine and a fatal arrow wound in his left shoulder. Although these molecules are very stable in tissues, prior to this study it was unclear whether they could still be found in human tissues after thousands of years. They analyzed not only tissue samples from the Iceman, but also those from a mummy of a soldier fallen in World War I. Some molecules were found that were present predominantly in the ancient tissues.
Professor Meese, head of the Institute of Human Genetics at Saarland University, claims that the stability of these biomarkers is also important for people today.
Scientific examination of the mummy. While hiking in the southern Austrian mountains very close to northern Italy in October , Erika and Helmut Simon stumbled across the top half of a human corpse protruding from glacial ice. Along with some then unidentified materials which were collected and bagged, the corpse was taken for closer inspection to the University of Innsbruck, Austria. It became quickly apparent that rather than the corpse being a recent victim of the mountains, it was many thousands of years old being dehydrated, preserved and mummified by the ice which had encapsulated it.
It became apparent that the mummy was in fact one of the most significant archaeological finds of the century. His future was firstly dependant on one fundamental question — was he found in Austria or in Italy? This was important as the mummy was clearly of great scientific and monetary value. The border in this region disputed for centuries under the current agreement signed in after WW1, depends upon the line between the highest rock ridges in the area i.

The Iceman mummy, nicknamed Ötzi, was discovered in amidst sheets of Ötzi opened a crucial window on the burial rituals and political strategies of a significant artifacts dating to the same period surfaced at similar highaltitude.
The discovery of the year-old mummified body and the associated artefacts created a media frenzy and great public interest. A wealth of scientific papers, popular books and documentaries have been published. How else could the body and artefacts be so well preserved? From the start, it was believed that he was a unique find, preserved by miraculous circumstances.
Otherwise, there would surely have been more such finds. It was six years before the first mass melt-out of archaeological finds from the ice in Yukon in and a few years later in the Alps and Norway more on the history of glacial archaeology here. When the first examples of a new type of find are discovered, they will sometimes appear surprising and odd. As time passes and more finds are made, this situation normally changes.
The earliest finds no longer appear peculiar, but fit a pattern that was not visible initially. We have seen the same thing happening during our glacial archaeology work here in Innlandet County, Norway. Finds that initially appeared odd and hard to understand, turned out to fit a pattern not visible to us, when we first started out. There are now hundreds of sites and thousands of finds.
