mysteries abound

Have you ever heard of the Longyou Grottoes in China? As a longtime admirer of a good mystery this one caught my interest when I first read about them a year or two ago, but unfortunately, there isn't really a lot of information other than some pictures and a few articles to be found on the internet.

Discovered in 1992 by a curious farmer (or an old lady called Grandma Wu depending on which account you accept), who wondered if the pond near his village was one of the legendary 'bottomless' ones, he convinced his neighbours to share in the rental on a pump so they could see for themselves. Now while I can't really understand why poor villagers would want to disrupt their supply of fresh water, they apparently kept pumping water from the squared off hole long enough to discover it was actually a purpose made cavern of pretty enormous size. Already ninety-eight feet deep, the floor itself sprawled to enclose an area of nearly thirteen thousand square feet - supported by carved pillars. The ceiling, wall and pillar surfaces are all finished the same way with a series of parallel bands between ridge marks about twenty inches wide and containing parallel chisel marks set at an angle of about 60°.

Once the first grotto was reported to the authorities a further twenty-four (or thirty-five) were found, all isolated from one another and often separated by less than two feet of stone. One fact from Wikipedia was curious. “Despite their size and the effort involved in creating them, so far no trace of their construction or even their existence has been located in the historic record.” Carved in siltstone, a medium-hard rock, the grottoes are thought to date to a period prior the Qin Dynasty in 212 BCE. However, there is not a single ancient text that describes the underground complex nor its creation or its purpose. Furthermore, there's no sign anywhere given the fact that the Ancient Chinese were extremely meticulous record keepers, of where nearly thirty-five million cubic feet of excavated rock went. When it's mentioned it would have taken a thousand workers each carting one hundred buckets twenty-four hours a day for six years (going where?) I can only shake my head in perplexity.

Commenting on the Longyou Grotto Caves, Yang Hongxun, an expert at the Archaeological Institute of Chinese Academy of Social Sciences, explained:

“At the bottom of each cave, the ancient builders wouldn’t be able to see what the others were doing in the next grotto. But the inside of each cave had to be parallel with that of the other, or else the wall would be holed through. Thus the measure apparatus should have been very advanced. There must have been some layout about the sizes, locations, and the distances between the caves beforehand.”

Another of the grottoe's mysteries is that there’s no evidence of lighting having been used. At Longyou there are no traces or remnants of the lamp bases, oil plates or other lighting equipment that have been found in other Chinese caves. Carbon residue remains on rock permanently. How did the builders see what they were doing when excavating and how did they breathe? The entrances are small and the caves deep, there would have been little to no natural light. It's a mystery.

Most of the spectacular mysterious ancient caverns are still full of water and neglected. This may be a good thing since Trip Advisor states the most bizarre thing is the level of destruction that has gone on in the ones that are open to the public. Concrete has been poured over them, lights and speakers installed, large fish ponds built inside the grottoes, and modern carvings have been added to the walls. By trying to attract tourists the government has destroyed and defaced the ancient cultural historical and architectural wonder. Alas, the Chinese were once understood to be very sensitive to ancient culture.

The general assumption about the grottoes is that they were man made about twenty-five hundred years ago, but I wonder. Not so much that people couldn't have made them, but the timing of their fabrication. While our race is estimated to be two hundred thousand years old our history dates back less than ten thousand years. Many ancient and mysterious artifacts and constructions have been found and are still being found. We don't know everything.

Maybe I'll ask Crow.

ps: article of the week

Amazing!! Makes one wonder and respect the engineering skills of those people so long ago. The photos are so beautiful. Today's attitudes about preservation are sadly very questionable though.

You do find such fascinating stuff; archaeology is a pet interest of mine, so a huge thanks to you and to Crow (perhaps he can find out more)!

Happy January! We are starting to thaw out from an unusually long and cold spell. How about you?

Should Fish More said...

I like that there are still such mysteries in our world. I am a scientist, I made my living in the field applied to medicine. Yet, there are things we cannot explain, or understand. Good. As it should be.
Yes, ask Crow. And before I have my next cardiac procedure in a week or so, if he has any info he'd pass on the events around Poe's demise, I'd like to know.

susan said...

Thank goodness there are places better preserved than these and, hopefully, there are many more yet to be discovered. Seeing fragments of our ancient and mysterious world history gives me hope for the future.

I tried to find pictures taken before much 'restoration' work had been done, so I'm glad to know you liked these, Marja-Leena. Crow knows far more than he tells, but I'm working on him. The Remy helps. :)

I'm glad your temperatures are normalizing. I saw similar disruption was going on in Portland too. Ours has been weird as well with bouts of serious cold and snow followed by several days of heavy rain. Yesterday it was 50F and today was 0F - quite a change. Of course, normal here means more of the same until April.

susan said...

I agree, Mike. Someone once said our body of knowledge is like having the light of a candle flame in a dark place while we look for more candles.

I will ask Crow. We've talked about Poe, but he was off telling tales to young Ambrose Bierce at the time. Another mystery.

We wish you well at your next procedure.

Hi Susan,
The discovery of the Longyou Grottoes in China is fascinating and the pictures amazing. An integrity and wisdom resplendent in ancient hand carved engineering, which seems in sync with the best in modernity. The surrounding geology has no doubt been sufficiently stable for the underwater structures remain intact and allow us such a splendid bird’s eye, maybe dating back at least 2000 years or more.
Maybe Crow can indeed claw-back samples from the cave walls for testing, along with his scientific cronies, to provide more clues. But not just for our curiosity I hasten to add, if it risks damaging his elegant plumage.
Best wishes

Tom said...

I'm simply too amazed to add anything further. I'll be interested to know if Crow has some answers.

susan said...

Hi Lindsay,
Seeing photographs of these grottoes is intriguing enough to allow us to understand the wisdom of our ancestors in staying more closely connected to the natural environment even as they shaped their own places in it. While it's interesting to speculate about just how old they may be the fact is that stone can't be carbon dated, only material that was once living. Even my dear friend Crow can't get around that one. Otherwise, he'd risk a little temporary damage to his plumage.
All the best.

susan said...

I'm delighted to have brought this place to your attention, Tom. There's something almost dizzying about contemplating the mystery behind it's construction.

Andrew R. Scott said...

That is rather amazing. Thanks.

Sean Jeating said...

Definitely fake news. Apart from that the savages in ancient time had no tools like twitter at their hand to get their wisdom trumpeted: Such things could not be done without Astro Teller's mastermind and Silicon Valley's various other unicorns and moonshooters.

susan said...

It really is. You're welcome.

susan said...

It would appear we have entered the age of fake reality, Sean. It's amusing that so many people think our society is the penultimate achievement possible for mankind to attain.. until tomorrow, that is.

Astounding discovery And mysterious...:)

susan said...

Now I'm very happy to have written the post. :)

Ol'Buzzard said...

I never heard of these caves - interesting. Like the mysterious drawings on the earth in Peru - on answer.

History is always fascinating, but history that approaches the mythical is better still.

wow. ancient bunkers... what were they hiding from?
