Anybody here interested in ancient technologies?


There are archaeological discoveries out there that have left scientists dumbfounded, inventions that occasionally paint a very different picture of our ancient world. Ancient inventions can be groundbreaking, giving us more insight into past cultures, people, and technology. Sporadically, researchers do find inventions that seem to be way ahead of their time, with a few of them almost impossible to recreate even with our modern technology.

From analog computers that are thousands of years old to lost military technology, there are some ancient discoveries worth looking into. What makes a lot of these lost technologies so interesting is how revolutionary they would have been if they caught on by now.


Houfeng Didong Yi: The ancient earthquake detector

Every year earthquake detection technology is getting far more advanced, detecting a natural disaster before it happens, and saving lives. However, the technology may not be that new. Dating back to 2,000 years ago to ancient China, the Houfeng Didong Yi, a seismoscope, was the first earthquake detection device recorded in history, and it was actually very effective. The person who created the tool was Zhang Heng. Dubbed the Leonardo da Vinci of China, the renaissance man was an inventor, astronomer, engineer, scientist, scholar, and artist.

Though his long list of work and accomplishments are all worth mentioning, his Seismoscope takes the cake. The Houfeng Didong Yi was able to detect earthquakes hundreds of kilometers away remotely. The jar device featured eight tubed projections shaped as dragon heads on the exterior, with eight corresponding toads at the base of the jar. Each of the toads represented a direction in which the seismic wave was traveling. To indicate the direction of a distant earthquake, the ancient invention would drop the ball in one of the toads.


Automated Doors: The Greeks had them before you

Automated door technology made its appearance in 1931 and was considered to be one of the signs of the "modern" age. Yet, the world had already seen this technology all the way back in 1 AD. So how did it work?

If you wanted to open the door a fire would need to be lit to generate heat causing an atmospheric build-up in ***** vessels. This vessel would then pump water in holding containers, and these functions would act as weights to open the door. Think of it as a hydraulic system. Unfortunately, the doors were not that practical and not as popular as the modern doors you have around your city.

The ancient doors actually took hours to open and the process was hard to stop once it started. So, this probably meant that you only opened your doors once a day.


Baghdad Battery: The ancient version of the battery

This is easily one of the more controversial ancient inventions on this list. Even more so, the ancient device was stolen in 2003 and has yet to be found. As its name implies, the Baghdad Battery, also known as the Parthian Battery, is a 2,000-year-old ancient artifact that could be an ancient version of a battery. The ancient invention was discovered in 1983 by a German archaeologist in Khujut Rabu, an area right outside of Baghdad.

Inside the clay jar, you will find a copper cylinder and iron rod. If you were to pour a weak acid into the clay jar, something like vinegar or even grape juice, the combination would cause the "battery" to generate about 1 volt of electricity. However, why would an ancient civilization need a battery?

At the moment, that is unclear. In fact, to this day, archeologists have only found one battery. Even more so, there is no written record describing the exact function of the jar. However, researchers have a few prevailing theories about ancient inventions. The Baghdad Battery was potentially used to electroplate items, the act placing a layer of one metal onto the surface of another. Another idea is that the device was used in religious ceremonies.

I used to like reading about how certain things were invented, but now I have little free time for this.
