Pollen Study Points to Culprit in Bronze Era Mystery - NYTimes.com - 0 views

To the north lay the mighty Hittite empire; to the south, Egypt was thriving under the reign of the great Pharaoh Ramses II. Cyprus was a copper emporium. Greece basked in the opulence of its elite Mycenaean culture, and Ugarit was a bustling port city on the Syrian coast. In the land of Canaan, city states like Hazor and Megiddo flourished under Egyptian hegemony. Vibrant trade along the coast of the eastern Mediterranean connected it all.

Experts have long pondered the cause of the crisis that led to the Late Bronze Age collapse of civilization, and now believe that by studying grains of fossilized pollen they have uncovered the cause.

unusually high-resolution analysis of pollen grains taken from sediment beneath the Sea of Galilee and the western shore of the Dead Sea, backed up by a robust chronology of radiocarbon dating, have pinpointed the period of crisis to the years 1250 to 1100 B.C.

the uniqueness of the study also lay in the combination of precise science and archaeological and historical analysis, offering the fullest picture yet of the collapse of civilization in this area at the end of the Bronze Age. “Egypt is gone. Forever,” said Professor Finkelstein. “It never got back to that level of prosperity again.”

the team extracted about 60 feet of cores of gray muddy sediment from the center of the Sea of Galilee in northern Israel, passing through 145 feet of water and drilling 65 feet into the lake bed, covering the last 9,000 years. At Wadi Zeelim in the southern Judean Desert, on the western margins of the Dead Sea, the team manually extracted eight cores of sediment, each about 20 inches long.

Pollen grains are one of the most durable organic materials in nature, she said, best preserved in lakes and deserts and lasting thousands of years. Each plant produces its own distinct pollen form, like a fingerprint. Extracting and analyzing the pollen grains from each stratum allows researchers to identify the vegetation that grew in the area and to reconstruct climate changes.

The results showed a sharp decrease in the Late Bronze Age of Mediterranean trees like oaks, pines and carobs, and in the local cultivation of olive trees, which the experts interpret as the consequence of repeated periods of drought.

The droughts were likely exacerbated by cold spells, the study said, causing famine and the movement of marauders from north to south. After the devastation came a wet period of recovery and resettlement, according to the experts — a new order that gave rise to the kingdoms of biblical times.
