Roman dodecahedron

A Roman dodecahedron is a mystery, no one can explain it, no conclusion, because scientists have not found any books about it written by the ancients. Many scientists have tried their best to prove its use, but in the present, they had no result.

Who invented them?
The ancient Roman invent them in 2nd or 3rd centuries AD.

Who found them?
A lot of scientists found them. Some scientists are came from Rome and many scientists are from other countries. They have been cracking its use.

Where were them found?
It is said that there were finding from France, Germany, Sweden and other places.

When were them found?
The first Roman dodecahedron was found in 1739.

Color and shape
Most of them have bronze color and they have twelve sides, twelve pentagonal, while some are made of bronze others are stone.

News about them
Now it's still a mystery.It seems to be hard to crack.

Where are they saved now?
Now they're in the Birmingham Museum and other museums.

Science and technology
They are very complex, scientists may need to use a lot of mathematical formulas and geometry to them to find out want are they used for.

Secret of them
A lot of scientists fought tooth and nail to proved what is it used for, but finally there is no conclusion.

Meaning of them
It maybe something used for religious ceremonies in Rome.

What they represent
It represents the wisdom and mystery of the ancient Roman.

What was a Roman dodecahedron used for?
According to Ancient-origins.net and Richardcarrier.info undefined, we found that a Roman Dodecahedron...

1. Candlestick holders
Some scientists found that some melted wax in a Roman dodecahedron, so they gress it was to be a candlestick holder. But some scientists think it was impossible because max will leak out from the bottom and the light of the candles will be covered by the shell, it's too difficult to use if it's a candlestick holder.

2. Dices
While some scientists think that it's just a dice but others don't. Because the dice in Rome is solid and It has numbers or words on it, but a Roman dodecahedron hasn't these things, they think it's impossible to be a dice.

3. Calculate a date to grow crop
Say it in a easy way, a dodecahedron may used as a calendar. A huge amounts of scientists think it's impossible, because it's very inaccurate to calculate a date. And at that time Rome already had objects that could accurately calculate the time.

4. Calibrate water pipes
Calibrate a water pipe is using a tool to measure the size and the outer end of the water pipe. Some people think ancient Roman use the Roman dodecahedron to calibrate water pipes, a huge amounts of scientists also think it's impossible, It hasn't a scale and the size is wrong, too hard to calibrate water pipes.

5. For army
Some dodecahedrons were found in ancient military bases, so some people think it used for army standard  bases,  but lots of scientists think it was too small and weak, they laid out a bunch of calculations to prove the theory wrong. Or it was just a toy used by Roman soldiers to kill time, they threw stones in the hole of a dodecahedron to gained the winner.

6. Religion
Some people said that it was used for a sacred tool in two ancient places, but there is no historical record about this theory.

7. Glove Knitters
A man called Martin Hallett used a 3D printer to made a dodecahedron and played with it. He found that he can knitted some gloves with it.

The videoundefined shows that how to knitting with a dodecahedron.
