Best Digital Lock - Basically, you might already be familiar with locks and keys.

The lock is a device that will protect something so people cannot open it. The one who can open it is only people who have access to its keys. 


However, even if you are already familiar with that, there are still so many shocking facts about locks and keys. 

Do you know who the inventor of the original lock? Also, who are the people that develop them until it is commonly used in modern society? What kind of historical events happened regarding them? Or other shocking facts that you still do not know about them even though you see them almost every day?
Here are some fun and unique facts that you can learn!
1. The Egyptians Were The Ones who are Inventing Locks

When talking about who invented locks and keys, one of the first societies that used them was the ancient Egyptians.

According to the archaeologists, they started using them around B.C. 2000. However, the name of the first person who used it is not mentioned in history up until today. 

Then, how unique are locks around that time? 

Considering the Egyptians were one of the most advanced civilizations of that era? At that time, the Egyptians were making locks by using wood.
It is kind of simple because you install two big pieces of wood with holes on the side between the door's crack. 

Then, on the hole, you can insert another wood, so people cannot open it on the outside. In general, the concept is not that different from public toilet locks, but with a more traditional vibe.

However, the usage of these locks is still very limited because you only can use them when you are inside the home. It is also easy to break with force because the lock was made from wood. So if you are curious about what is the oldest lock, the wood lock from the Egyptian civilization is the answer.


2. The Romans Were The Ones who are Developing Locks

Interestingly, one of the fun facts about locks is the one who develops it. As it is stated before, the locks that are made by the Egyptians are not strong enough. 

So, the Romans tried to strengthen its security by changing its material. When the Egyptians made it from wood, the Romans made it from metal. 

However, the development did not happen in a short period after the Egyptians invented them. Because, the Romans only invented the metal locks in the first century, around 870 to 900. 

They made the locks for better security. Aside from that, they also invented locks that can fasten and unfasten outside. 

So, if you want to know how old the oldest key is, the metal one was invented in the first century. While the wood one was invented in the B.C. 2000. There is a gap of around 3000 years between those two. 


3. Locks and Keys Become The Symbol of Love in Literature

Not only for practical use, people also started to use locks and keys in literature. Especially in the 14th to 17th century, when the Renaissance era started to occur in Europe. 

At that time, people started to learn more about humanity. They start writing scripts for plays, poetry, and prose. 

At that time, they also learned about parables in their book. Reflecting on how locks were invented, that is to protect something precious to you from other people, locks and keys become a symbol of love.
William Shakespeare, who is one of the most famous writers in English literature, also has written about locks and keys before. 

He is the one who wrote, "This in my memory lock'd, and you yourself shall keep the key to it", which is considered a romantic phrase.

In today's society, the thing about "locks and keys are the symbol of love" is still relevant. 

So, it is not surprising that many couples write their name on a padlock and throw away the key. They are doing that with the hope that their love will last long. 

Some countries like France and South Korea even make it a tourist attraction. Not only for romantic love, some people also write on the padlock with their best friend or family. Because platonic love and familial love is also important in people's life.

4. Making Locks and Keys is King Louis XVI's Hobby

As you might already know, the revolution happened because the royals and the noblemen failed to prosper the people. The people are poor and hungry, and they go on a spree with the state's coffers are running low. Their kings were also considered useless and often made detrimental policies. 

The reason is that the king, Louis XVI, was not that interested in politics. He likes to spend his time in the basement making locks and keys more. Unexpected, right?


5. Ancient Chinese Commonly Use Animal-Shaped Locks

Aside from Europe and Egypt, the importance of locks and keys to protect the home and to give privacy is also known in Asia. For example, it was commonly used in China, as one of the most advanced civilizations in Asia at that time. 

When talking about what are the most unique locks and keys, then ancient Chinese locks are definitely one of the answers. 

Like the ancient Romans, they made it by using metal. However, the design is very unique because it is very similar to the shape of animals. 

Aside from the traditional ones, the animal figures are also found in the padlocks. There are the figures of elephants, dragons, hippopotamuses, horses, and other animals that are important in China's history and philosophy. 

This is because they believe that the locks and keys will protect them from evil spirits. 

They also use it to fulfill certain wishes, either hoping to be happy or to have good fortune. So, aside from security, there are also belief essences in the purpose of locks and keys for ancient Chinese at that time.
