What climate science can tell us about the lost world that inspired The Odyssey
New study suggests drought added pressure as Bronze Age palace societies collapsed
By the time The Odyssey was composed, the Bronze Age palace societies that helped inspire its fictional world had been gone for centuries.
uncertain
that → tell → centuries
Palaces had fallen, trade networks had fractured and populations had shifted across the eastern Mediterranean.
asserted
populations → fall → Mediterranean
Now, a new climate study suggests that centuries of repeated severe drought added to the pressures on that collapsing world.
uncertain
centuries → suggest → world
Published in Science Advances, the study models drought conditions from roughly 1400 to 900 BC, overlapping the collapse of Mycenaean palace society in Greece and the Hittite state in what is now Turkey.
asserted
what → publish → Greece
Cave formations, lake sediments, pollen and other natural records had already shown evidence of drought.
asserted
formations → show → drought
The new model helps explain how several natural climate patterns may have aligned to intensify it, offering a historical backdrop to the scarcity and upheaval that echo throughout The Odyssey's fictional world.
uncertain
that → help → world
Katherine Power, the study's lead author and a PhD student in physical geography at Stockholm University, says the model found a long-term shift toward drier conditions across parts of the eastern Mediterranean.
asserted
model → say → Mediterranean
Several shorter-term climate patterns then aligned in ways that intensified drought around the time of the Late Bronze Age collapse.
asserted
that → align → collapse
Those shorter droughts would not necessarily have been catastrophic on their own, Power said, but because they occurred on top of a long-term drying trend, their effects were amplified.
asserted
effects → say → trend
"Everything sort of happened at once, and that was very bad luck for them," Power said.
asserted
Power → happen → them
Power and co-author Qiong Zhang, a professor of physical geography at Stockholm University, reached that conclusion using a computer model that simulated 8,000 years of climate change, including shifts in Earth's orbit, greenhouse-gas concentrations and interactions among the atmosphere, oceans, vegetation and soil moisture.
asserted
that → reach → atmosphere
Power says the combined effects could have meant shorter wet seasons, weaker harvests and strained water supplies, adding pressure to already stressed societies.
uncertain
effects → say → societies
"We never want to say that climate was the sole driver," Power said.
asserted
Power → want → ?
"We want to say that climate may have exacerbated problems that were already going on.
uncertain
that → want → problems
"
When connected systems fail
Lynn Welton, an assistant professor of Near Eastern Archaeology at the University of Toronto, praised the study for showing how the region's climate changed over time and placing local evidence within a broader regional picture.
asserted
climate → connect → picture
In the Late Bronze Age, the eastern Mediterranean was bound together by trade, diplomacy and political alliances, allowing disruption to spread when major centres weakened, Welton told CBC News from Tell Tayinat, an archaeological site in southern Turkey that preserves evidence from the transition between the Bronze and Iron Ages.
asserted
that → bind → Ages
"What characterizes this period is the disintegration of a lot of the international systems that existed during the Late Bronze Age period, but how different regions responded in the subsequent period varies quite a bit," Welton said.
asserted
Welton → characterize → period
Writings from the period also point to food shortages and dependence on grain shipments.
asserted
Writings → point → shipments
"We have some texts that seem to indicate that there were droughts or famines," Welton said.
asserted
Welton → have → texts
Other records describe poor harvests and reliance on grain shipments from elsewhere.
asserted
records → describe → shipments
If harvests failed in several places at once, she says, trade could no longer provide the same protection.
uncertain
trade → fail → protection
Welton cautioned that the term "collapse" can obscure as much as it reveals.
asserted
it → caution → much
The Hittite state ended and the Mycenaean palace economy disappeared, for example, but she says that doesn't mean communities everywhere vanished.
asserted
communities → end → example
Some cities continued with little evidence of destruction, she said, while others show newcomers, changing material culture and political reorganization.
asserted
others → continue → culture
"Not all regions collapsed at the same time, at the same rate, in the same ways," Welton said.
asserted
Welton → collapse → ways
The imagined age behind the poem
Centuries after the Bronze Age palace societies disappeared, The Odyssey imagined a heroic world of palaces, warriors, vulnerable households and perilous journeys.
asserted
Odyssey → imagine → palaces
Most experts agree that the poem cannot be read as evidence of a historical drought or Bronze Age migration.
asserted
poem → agree → drought
But its recurring concerns — scarcity, displacement and social disorder — echo pressures familiar in a region shaped by environmental and political upheaval.
asserted
concerns → recur → upheaval
Jonathan Burgess, a University of Toronto professor emeritus of classics and author of The Travels of Odysseus, says the poem doesn't preserve one clearly defined historical era.
asserted
poem → say → era
"It's just a hodgepodge," Burgess said.
asserted
Burgess → say → ?
"The material and cultural aspects of Homer come from different time periods.
asserted
aspects → come → periods
"
A recurring theme in the poem is the role of food insecurity in shaping the epic's action.
asserted
theme → recur → action
"Hunger is very important," Burgess said.
asserted
Burgess → say → ?
Because their wanderings are unplanned, the crew repeatedly arrives in unfamiliar places without reliable provisions.
asserted
crew → arrive → provisions
"They don't know where they are.
asserted
they → know → ?
They're just landing at places here and there."
Their search for food helps draw the crew into the cave of the Cyclops.
asserted
search → land → Cyclops
Later, adverse winds trap them on the island of Helios until their supplies run out.
asserted
supplies → trap → Helios
Facing starvation, the crew kill the sun god's sacred cattle despite repeated warnings.
asserted
crew → face → warnings
"They'd rather eat now and drown later than just die by starvation," Burgess said.
asserted
Burgess → eat → starvation
Scarcity also threatens order in Ithaca.

Scarcity → threaten → Ithaca
