The two men had found a body from the time of the Roman invasion of Celtic Britain.
Archaeology is an important field of anthropology, which is the broad study of human culture and biology.
Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.
If you visit London, you can go and see Lindow Man at the British Museum, where he is spending some time in the company of more famous mummies from Egypt.
Whereas the bodies of the Egyptian kings and queens were intentionally preserved, Lindow Man is with us by accident.
The men were cutting the peat when one of them saw something sticking out – a human foot!
Naturally, the men called the police, who then found the rest of the body. Possibly – but it was a death nearly two thousand years old.We also know a lot about them from what they made, from their coins to their buildings.Archaeologists have worked on Roman remains as far apart as Hadrian’s Wall in the north of England and Leptis Magna in Libya.The archaeologists believe that he was sacrificed to three different Celtic gods, called Taranis, Esus and Teutates. A sacrifice to Teutates required drowning, which is why he was found in the bog. The Romans said that the Celts made sacrifices every May to make sure that there was enough food that year. An archaeologist called Anne Ross has suggested that Lindow Man was a special case.Why would an important man be sacrificed to three gods?The movement of our ancestors across the planet has been mapped from their remains – humans went to Australia about 70,000 years ago, but have been in South America for just 15,000 years.
