New pollen samples dug out of the bottom of the Sea of Galilee (Lake Kinneret) by an Israeli scientific team suggest that a regional drought seems to have been the reason why prosperous societies –– Egyptian, Hittite and Mycenaean –– collapsed more than 3,000 years ago.
The recent study by Dafna Langgut and Prof. Israel Finkelstein of the Institute of Archaeology at Tel Aviv University (TAU); Prof. Thomas Litt from the University of Bonn, Germany; and Prof. Mordechai Stein from the Hebrew University appeared in the October issue of Tel Aviv: Journal of the Institute of Archaeology of Tel Aviv University.
The study explains short-term and cataclysmic climatic changes in the region. In addition, the new research opens up a new way for scientists to compare records and substantiate them.
Looking at pollen at the micro-scale of 40-year gaps, the researchers discovered a shift in vegetation that corresponds to a drought that heightened in the years between 1250 and 1100 BCE. This drought presumably could have created a snowball effect on trade, farming and societies themselves.
How pollen fells the mighty
What fascinates historians is the quick timescale in which these ancient centers of power disappeared from the world stage. “In a short period of time, the entire world of the Bronze Age crumbled,” says Finkelstein.
“The Hittite empire, Egypt of the Pharaohs, the Mycenaean culture in Greece, the copper-producing kingdom located on the island of Cyprus, the great trade emporium of Ugarit on the Syrian coast and the Canaanite city-states under Egyptian hegemony – all disappeared and only after a while were replaced by the territorial kingdoms of the Iron Age, including Israel and Judah.”
Finkelstein, a noted archeologist, is more pragmatic and prefers not to talk about the mysterious Sea Peoples who may have pillaged and stormed the empires in the region back then. (In fact he hung up the phone when I asked him the question: saying – “this interview is over”, when I was writing a piece for ISRAEL21c.) This is a theory suggested by his former student, Egyptologist Shirley Ben-Dor Evian. Neither is he willing to connect the Bible’s narratives to what he finds using the tools of archeology.
Pollen, however, provides scientific evidence. Using pollen records to understand the past is not a novel idea, even in Israel where Langgut, a palynologist (pollen expert), has used pollen findings to reconstruct ancient gardens.
The most enduring organic material
Langgut, who carried out the actual studies of 20-meter-long samples drilled from 300 meters down into the heart of the Sea of Galilee – Israel’s only inland lake — says that “pollen is the most enduring organic material in nature.”
She explains: “Pollen was driven to the Sea of Galilee by wind and river-streams, was deposited in the lake and was embedded in the under-water sediments. New sediments that are added annually create anaerobic conditions which help preserve the pollen particles. These particles tell us about the vegetation that grew in the vicinity of the lake in the past and therefore testify to the climatic conditions in the region.”
The lake, with its stories, sediments, and recovered ancient fishing boats and other artifacts, can reveal much about the factors that have shaped the land of Israel.
“The novelty [of the study] is mainly in the resolution, which concentrated on a short period of time with a good control of radiocarbon dating,” Finkelstein explains.
And, he adds, the study was unique because it made use of more than one record — pollen records, archeological and textual records.
Will work like that done at the Sea of Galilee be able to shed light on the political and societal effects of advanced climate change and the world droughts that are predicted for the next hundred years and beyond? Only time will tell.
