1, Roman dodecahedron

These fist-sized ancient Roman bronzes were found in France, Switzerland and Germany, which posed an interesting question to archaeologists: not only did they have no clear purpose, but many of them were engraved with various symbols and signs, some of which were difficult to recognize, while others were definitely related to the Chinese zodiac.

There are various speculations about the use of "Roman dodecahedron", such as measuring instruments. Some experts think that they are just decorative candlesticks.

2. Voynich manuscript

Is the Voynich manuscript evidence of lost civilization, or is it just an elaborate scam? This manuscript written in a strange font was discovered by Wilfrid Voynich, an American bookseller, in a Jesuit university library near Rome in 19 12, dating back to15th century.

There are many strange pictures of plants, celestial bodies and bathing beauties, but even the top cryptographers and code translators in the world can't decipher the words in the manuscript. If it is a scam, the credibility is also very high, because the text in the manuscript is very smooth, and statistical analysis also finds that the graphics inside are very similar to those in natural language.

3. Festus disc

We really know very little about "PhaistosDisc". This is a clay disc, which can be traced back to around 2000 BC. However, its origin, significance and use are still a mystery.

The "Festus Disc" (also translated as Festus Disc or festo Disc) was discovered in Crete. There are 24 1 marks on the disc, representing 45 different symbols, some of which represent people, animals, plants and tools. However, because no cultural relics like this have been found in the same historical period, archaeologists cannot make a meaningful analysis of their contents.

4. Shroud of Turin

The "Shroud of Turin" is a piece of linen, which shows a person being crucified. It has been the focus of controversy since it was first discovered in the Middle Ages. According to legend, this linen cloth once wrapped Jesus' body and has always been regarded as sacred by Christians. Radiocarbon dating shows a range from 1260 to 1390. It is not the shroud of Jesus, but it is consistent with the statement that it is a fake. However, these test results have been controversial, and since then, a series of modern technologies have been unable to explain the traces on this linen.

5. Anthich Sila machine

Antichi Silas Machine is considered as the oldest computer in the world, which is about 2000 years earlier than the computer developed by Bill Gates. In fact, the absolutely incredible Antichi Sila machine may prove that the history of advanced technology is much earlier than we thought. It was found in a sunken ship near the Greek island of Silla in Anthich. It looks like a clock.

Scientists later discovered that this mysterious ancient Greek invention could predict the solar eclipse and set the calendar as a four-year cycle, which was also related to Archimedes, a great ancient Greek scientist. Although no device like Anthich Silas machine has been found so far, scientists believe that many such devices existed at the same time around 100 BC.

6. Costa Rica giant stone ball

In 1930s, George Chitan, an American, discovered countless stone balls in the Dikis Delta and Isla de Cano in Costa Rica. These stone balls vary in size, with the large diameter of 6.6 feet (about 2 meters) and the small diameter of only a few centimeters. The spherical surface is extremely smooth and can distinguish light. This is an ideal sphere.

Maximum stone ball weight 16 ton. It's hard to imagine how the ancients moved these behemoths made of granodiorite here, because the nearest quarry is 50 miles (about 80.5 kilometers) from where the giant stone balls were found. There are more than 300 such stone balls scattered all over Costa Rica, and we will never know the reason: their age can be traced back to AD 1000, and their makers have been buried for a long time without any written records.

7. Baigongshan Iron Pipe

"China Discovers Ancient Toilet" is one of many strange news headlines about the origin of Baigongshan iron pipe. Scientists have found hundreds of rusty iron pipes left over from ancient times on the top of a mountain named Baigong Mountain in Qaidam Basin, Qinghai, China, and there is a salt lake nearby. Scientists still don't know the origin of these iron pipes. What's so strange about them?

First, they were found in a completely uninhabited place-scientists didn't find any signs of civilization there. Secondly, the iron pipes are the same size and seem to be arranged in a certain pattern. There is no clear statement about the existence of these iron pipes, and scientists seem to have differences on whether they belong to natural products.

8. Baghdad battery

When electronic equipment did not exist, what did the ancients do with batteries? "Baghdad Battery" was found outside Baghdad, the capital of Iraq (1936). It is a small clay pot. Iron bars are hung in a copper cylinder and welded together, and the outside is covered with asphalt.

This clay pot looks like the shell of a battery in appearance. Since then, the device imitated by scientists according to the "Baghdad battery" can indeed generate electricity, although it is rare, thus proving the power generation ability of small clay pots. However, the question of what the battery did at that time has not been answered so far.

9. corzo cultural relics

After finding a spark plug in a rock block with a history of 500,000 years, pretentious investigators decided that there were three possibilities for it to appear there: First, it came from a highly developed ancient civilization (is it "Atlantis"? ); Second, aliens visited the earth in the dinosaur era; Third, time travelers from the future left clues in the distant past.

The above three explanations are unlikely to be correct, but scientists have not come up with a better explanation so far-perhaps because the "synergy effect" has mysteriously disappeared, so there is no physical object for scientific analysis.

10. Maine coin

1957, archaeologists discovered real Norwegian coins dating back to165438+the early 20th century at Indian ruins in Maine, USA. This discovery also provides an interesting evidence that the vikings had reached a place farther south than Newfoundland before the Italian navigator Christopher Columbus. Although this possibility exists, experts have also raised their own doubts.
