Most armors try to cover as many gaps as possible, but this doesn't seem to be the case of the mirror armor. This armor often only has one large plate protecting the chest, and another protecting the back, leaving arms, legs, shoulders, sides, etc, open. Why is this the case? Was it just a primitive and easy to make armor, or was it done on purpose?

Video Summary
AI GeneratedThis video explores \"mirror armor,\" a style of protection characterized by large plates covering vital areas—primarily the chest—rather than the entire body. It examines the historical prevalence of this design across various cultures and explains the practical reasons why leaving gaps in armor was often a strategic choice rather than a primitive mistake.
Most armor is designed to cover as much of the body as possible. If there are gaps,
you try to close them, overlap them, or make them harder to reach. But then you have armor like
the mirror armor. Instead of covering every weak point, it leaves huge parts of the body exposed
and only protects certain few areas, usually mainly the chest. So why did people use armor
like this? Was it just primitive, or was this done on purpose? Let's find out.
So the term mirror armor actually covers quite a wide range of different armors that obviously
share certain similarities, but that were relatively different from each other,
and that were used in a whole bunch of different regions during a whole bunch of different eras.
For example, they were used quite a lot in the east, in certain regions like for example India,
China, or Russia. In periods like the late middle ages, renaissance, and even certain modern periods,
certain mirror armors were used until I think the 20th century. During the 20th century,
you have the last traces of actually being used. That is the region and era for which the mirror
armor is commonly known as being used, but similar forms of armor also existed way before that.
For example, the greeks had an armor that is called the cardiophilox, which basically just
means a heart protection, that is a similar sort of armor to that later mirror armor,
because as the later ones, it is basically made up of a plate covering the chest. On top of that,
the romans also used a similar armor to the mirror armor during the early republic. Obviously,
the romans are known for using all sorts of different armors like the loica homata, like the
male shirt. They would use other armors and one of those armors would be an armor that is very
very similar to a mirror armor, and in a sense is a mirror armor. Now obviously for those two
earlier examples, it does depend on what exactly you're calling a mirror armor, because the
calvary mirror armor, as I said, is quite vast, both in a geography and era, but also in exactly
what kind of armor you're talking about, because it is basically an armor made up of relatively
large plates covering parts of the body, but those plates could vary a lot in size, in shape,
some of them were rectangular, some others were round, and also in what area of the body they
actually covered. The very basic sort of armor will basically only have a plate on the front
protecting the chest, then you can also have another plate protecting also the back, that is
example what we see on armors like the cardiophilax, they would have one plate in the front, one plate
on the back, and also you can go even farther than that by adding a plate to the side, and you can
even go even further than that by adding some plates to the shoulders, that was sometimes done,
even though that is very very rare, and would be a very very advanced sort of mirror armor. The
plates are usually assembled using leather straps, meaning basically just leather straps connecting
each and every single metal plate together, but then again you do have certain differences
in between different mirror armors, you do have some that are connected with mails, basically just
mail, like chain mail, connecting different plates together, in a very similar manner to an other
armor that is called the mail and plate armor, but it's not exactly the same as a mail and plate armor,
it is considered a mirror armor, even though it is assembled in a similar manner to the mail and
plate armor. And finally you have all sorts of different ways to wear the mirror armor, it could be
worn as a standalone armor, just on top of normal clothing, using the plates alone as armor, but it
could also be worn over some form of other armor, like for example a form of fabric armor, like for
example mail, and even it could be worn over some form of lamella, even though then you're probably
going to be talking mostly about some organic material lamella armor, like for example leather
lamella, because the use of putting a metal plate on top of a metal lamella is very very limited.
So basically the term mirror armor is very very vast, can cover a ton of different armors that
will protect more or less, that will be worn in different contexts, used by different cultures,
during different periods, and so on. And to a certain degree it also depends what you want to
call mirror armor, do you really want to call the early cardiophilox and roman armors mirror armors,
or are those another kind of armor, and also those mirror armors that assemble in a similar manner to
the mail and plate armor, are you going to call that a mirror armor or not.
Generally speaking those are called mirror armors, at least they can be called mirror armors,
but it does depend whether or not you do want to call them. So yeah, the category is vast and
its limits are quite unclear. And if you're wondering why this sort of armor is called
a mirror armor, that is probably because the plates were polished up to a so large degree
that they would look like mirrors, at least in certain cases. Because across all the different
cultures that use this armor, or at least the vast majority of the cultures that use this armor,
the armor is called something in relation to mirrors, whether that is a mirror armor straight
up, or something like heart protecting mirrors, or something like that. And also there was a
certain belief, at least among certain of these cultures, that a mirror used as an armor would
repel certain evil spirits or something like that. Now obviously that style of armor, the
mirror armor, does look kind of bad in a certain kind of way, because it has a lot of gaps. As I
said some of them will only be made up of a chest plate and a back plate, meaning that obviously
you can hit on the sides of that plate, you can hit the arms very easily, you can hit on the sides
of the body and so on, you can hit on the shoulders. It leaves incredibly large areas of the body
unprotected. Obviously some of them are covering more parts of the body, some of them have larger
plates, some of them have plates on the side and so on, but generally speaking it will leave very
very large gaps. And the truth is that obviously, yes, it is not as protective as another armor
that will protect larger areas of the body, like for example like a plate armor or something like
that, or a brigandine or something like that. Those armors will protect larger areas of the body and
therefore will be more protective. But obviously you have the problem that metal is very heavy,
very expensive, and when you have it covering your entire body it can also be very very warm.
And this style of armor was primarily used in rather hot regions, obviously not only it was
also used in colder regions like for example Russia, but it was primarily used in colder
regions. If we look at the early examples, those are Greek and Romans, so rather hot climates and
Mediterranean, and also later in time it was also generally being used in rather hot climates
compared to certain other regions of the world. So by minimizing the amount of metal you're using
on your armor you're making more comfortable armor that is cheaper and that is going to be much less
warm to wear when it is very hot. And on top of that it also protects the most important parts
of the body to protect, because obviously as I said it primarily has a chest plate, and obviously
the chest is the part of your body where you have the most important organs, like for example the
lungs, like for example the heart, so it is very important to protect that area of your body. So if
you want an armor that's very light or you don't have enough metal or it is going to be too hot to
wear a full suit of armor or something like that, only protecting the chest is probably your best option.
And finally you also have the fact that as I said it was very very often only worn as a reinforcement
over other forms of armor. So you would in a lot of cases, obviously that now I'm talking primarily
in later periods of time, this was not the case among Greece and was not the case among the Romans,
but in later periods of time it was very often worn over some form of armor, like for example mail.
And obviously if you wear that armor over a mail shirt you already have the mail shirt protecting
all the gaps or the other parts of the body, so you only need to reinforce the most
vital parts of the body and the parts that are most likely to receive a very very strong hit.
Because mail alone might not be enough on the body itself because you can get quite a lot of
force in the hit on the body, but it might perfectly well be enough on the arms or something like that
because you have much more movement in your arms. If I get hit in the arm, a lot of that force is
going to be used to actually just push my arm away, which is not going to happen so easily if
I get hit from the body. So the mirror armor would come over other forms of armor to reinforce the
most vital parts of the body. And this is a big reason why this style of armor keeps reappearing
and was used by so many people. We even find similar design on today's bulletproof vests.
Today's bulletproof vest will basically have a big front plate, a big back plate, so that does show
that that style of armor does work and it is worth it to protect only the most vital parts of the
body because, well first of all, they are the most easy to protect and the most important to protect.
Because obviously you cannot make a full bulletproof suit, or theoretically you could, but it would be
incredibly impractical, so you are better off just having it on the most vital parts of the body.
Now of course the use of today's bulletproof vest and the threat it is supposed to face are very
different from the ones of the mirror armor, but to a certain degree it does show that that style
of armor, that design, does work. So in the end mirror armors definitely had a lot of problems,
like for example they don't protect gas very very well, and other armors, like for example obviously
plate armor, but also brigandine, and to a certain degree male shirts, were better armors. Because
obviously the romans had a similar style of armor to the mirror armor, but then switched to the
logohamata, so male armor, which probably is a big indicator that logohamata, male armor, was much
better. But all this being said, mirror armor can still make a lot of sense in certain cases,
like for example if it's very hot, like for example if you have a limited amount of armor that you can
wear, either because you can't afford more armor, or because you have a limit on how much weight you
can carry with you, the mirror armor is a way of having a very very light armor that will protect
very very well the most vital parts of the body. And it is a proven design, because as I said it
was used in a whole bunch of different regions across a wide range of periods, and is even to
a certain degree used today, or at least similar armors are used even today. So it definitely is
an armor that can make a lot of sense in certain cases. Anyways, hope you enjoyed the video,
and I'll see you in the next one.
