Ancient Seawall Found Submerged

被淹没的古代海堤

Go snorkeling in a lot of places, you’ll find coral. But on Israel’s Mediterranean coast?

去很多地方潜水,你会发现珊瑚。但在以色列的地中海海岸呢?

“I think it’s the only place in the world that you can find whole prehistoric villages submerged under the sea.”

“我认为这是世界上唯一一个你可以发现整个史前村庄被淹没在海底的地方。”

Ehud Galili is an underwater archaeologist at the University of Haifa. He says one submerged village, called Tel Hreiz, sits just a few meters under the water. The community was populated some 7,000 years ago.

Ehud Galili是海法大学的水下考古学家。他说,有一个被水淹没的村庄,名叫泰尔瑞兹,就坐落在水下几米的地方。这个社区大约在7000年前就有人居住了。

There, the archaeologists have found pottery and flint, human skeletons, the remains of deer, cows, pigs and dogs, and hundreds of olive pits—probably the remains of olive oil production. And the researchers also found a 300-feet stretch of huge boulders—a wall.

在那里,考古学家发现了陶器和燧石、人类骨骼、鹿、牛、猪和狗的遗骸,以及数百个橄榄坑——可能是橄榄油生产的遗迹。研究人员还发现了一段300英尺长的巨石墙。

After ruling out other possible uses for the wall—like defense against enemies or corralling animals—the scientists determined that the formation was actually an ancient seawall, the oldest known example in the world. The results are in the journal PLOS ONE.

在排除了墙状防御敌人或围捕动物的其他可能用途后,科学家们断定,这个结构实际上是一个古老的海堤,是世界上已知的最古老的海堤。研究结果发表在《公共科学图书馆·综合》杂志上。

The boulders that kept the waters of the Mediterranean from flooding the village came from riverbeds at least a few kilometers away. And the researchers say that it would have taken multiple people—or strong beasts of burden—to move them into place, suggesting that constructing the wall was a well-organized community effort. But eventually, the sea beat the barrier.

阻止地中海海水淹没村庄的巨石来自至少几公里外的河床。研究人员说,要把他们搬到合适的地方,可能需要很多人,或者是身强力壮的,这表明修建长城是社区精心组织的工作。但最终,大海冲破了障碍。

“Little by little, sea level continued to rise, and then it became no longer effective. At some point, the cost of continuing to struggle with the sea was too high economically, and they made a decision to abandon the village.”

“一点一点地,海平面继续上升,然后海堤变得不再有效。在某种程度上,继续与大海抗争的经济代价太高了,人们决定放弃这个村庄。”

Of course, our technology is far more advanced than what they had seven millennia ago. But this sunken seawall is still a warning of what can happen when humans battle rising seas.

当然,我们的技术比七千年前要先进得多。但这座沉没的海堤仍然是一个警告:人类与上升的海平面作战时,最后的结果可能会是什么。
