Meteor clue to end of Middle East civilisations

SCIENTISTS have found the first evidence that a devastating meteor impact in the Middle East might have triggered the mysterious collapse of civilisations more than 4,000 years ago.
satellite images of southern Iraq have revealed a two-mile-wide impact crater caused by a meteor
Studies of satellite images of southern Iraq have revealed a two-mile-wide circular depression which scientists say bears all the hallmarks of an impact crater. If confirmed, it would point to the Middle East being struck by a meteor with the violence equivalent to hundreds of nuclear bombs.
Today's crater lies on what would have been shallow sea 4,000 years ago, and any impact would have caused devastating fires and flooding.
The catastrophic effect of these could explain the mystery of why so many early cultures went into sudden decline around 2300 BC.
They include the demise of the Akkad culture of central Iraq, with its mysterious semi-mythological emperor Sargon; the end of the fifth dynasty of Egypt's Old Kingdom, following the building of the Great Pyramids and the sudden disappearance of hundreds of early settlements in the Holy Land.
Until now, archaeologists have put forward a host of separate explanations for these events, from local wars to environmental changes. Recently, some astronomers have suggested that meteor impacts could explain such historical mysteries.
The crater's faint outline was found by Dr Sharad Master, a geologist at the University of Witwatersrand, Johannesburg, on satellite images of the Al 'Amarah region, about 10 miles north-west of the confluence of the Tigris and Euphrates and home of the Marsh Arabs.
"It was a purely accidental discovery," Dr Master told The Telegraph last week. "I was reading a magazine article about the canal-building projects of Saddam Hussein, and there was a photograph showing lots of formations - one of which was very, very circular."
Detailed analysis of other satellite images taken since the mid-1980s showed that for many years the crater contained a small lake.
The draining of the region, as part of Saddam's campaign against the Marsh Arabs, has since caused the lake to recede, revealing a ring-like ridge inside the larger bowl-like depression - a classic feature of meteor impact craters.
The crater also appears to be, in geological terms, very recent. Dr Master said: "The sediments in this region are very young, so whatever caused the crater-like structure, it must have happened within the past 6,000 years."
Reporting his finding in the latest issue of the journal Meteoritics & Planetary Science, Dr Master suggests that a recent meteor impact is the most plausible explanation for the structure.
A survey of the crater itself could reveal tell-tale melted rock. "If we could find fragments of impact glass, we could date them using radioactive dating techniques," he said.
A date of around 2300 BC for the impact may also cast new light on the legend of Gilgamesh, dating from the same period. The legend talks of "the Seven Judges of Hell", who raised their torches, lighting the land with flame, and a storm that turned day into night, "smashed the land like a cup", and flooded the area.
The discovery of the crater has sparked great interest among scientists.
Dr Benny Peiser, who lectures on the effects of meteor impacts at John Moores University, Liverpool, said it was one of the most significant discoveries in recent years and would corroborate research he and others have done.
He said that craters recently found in Argentina date from around the same period - suggesting that the Earth may have been hit by a shower of large meteors at about the same time.

King Hammurabi is the best known of the early monarchs of ancient times... belonged to the First BabyIonian Dynasty which came to an end, under circumstances shrouded in mystery, some three or four generations after Hammurabi. For the next several centuries, the land was in the domain of a people known as the Kassites. They left few examples of art and hardly any literary works -- theirs was an age comparable to and contemporaneous with that of the Hyksos in Egypt, and various surmises were made as to the identity of the two peoples. A cartouche of the Hyksos king Khyan was even found in Babylonia and another in Anatolia, a possible indication of the extent of the power and influence wielded by the Hyksos. Until a few decades ago, the reign of Hammurabi was dated to around the year 2100 before the present era... At Platanos on Crete, a seal of the Hammurabi type was discovered in a tomb together with Middle Minoan pottery of a kind associated at other sites with objects of the Twelfth Egyptian Dynasty, more exactly, of its earlier part. This is regarded as proof that these two dynasties were contemporaneous... however... At Mari on the central Euphrates, among other rich material, a cuneiform tablet was found which established that Hammurabi of Babylonia and King Shamshi-Adad I of Assyria were contemporaries. An oath was sworn by the life of these two kings in the tenth year of Hammurabi, The finds at Mari "proved conclusively that Hammurabi came to the throne in Babylonia after the accession of Shamshi-Adad I in Assyria"... The Khorsabad list ends in the tenth year of Assur-Nerari V, which is computed to have been -745... the first year of Shamshi-Adad is calculated to have been -1726 and his last year -1694... it reduced the time of Hammurabi from the twenty-first century to the beginning of the seventeenth century... "a puzzling chronological discrepancy", which could only be resolved by making Hammurabi later than Amenemhet I of the Twelfth Dynasty... If Hammurabi reigned at the time allotted to him by the finds at Mari and Khorsabad -- but according to the finds at Platanos was a contemporary of the Egyptian kings of the early Twelfth Dynasty -- then that dynasty must have started at a time when, according to the accepted chronology, it had already come to its end. In conventionally-written history, by -1680 not only the Twelfth Dynasty, but also the Thirteenth, or the last of the Middle Kingdom, had expired.
