Bas-reliefs, in fact, are the same as drawings and many other images and works of art that allow you to understand at least some details of the life of the past and find out what people could see then. Since what a person observed, he most often reflected somewhere and this is understandable.
In general, in the world, I am sure, there are hundreds of bas-reliefs that somehow do not fit into the official history, but I will tell you about those that I know at the moment.
Yesterday, in a selection of 3 incredible temples, I wrote about the Hoysalesvara temple, where huge walls with bas-reliefs are probably counted not even in hundreds, but in thousands.
I'm sure you can find a lot of interesting things there, but since it is personally difficult to go there and explore every wall, I will write about those strange bas-reliefs that are known.
The first is a creature with a telescope. I do not know what it looks like, presumably it is something like a centaur, although it is unlikely that the centaur was in Indian mythology. But it doesn't matter.
Promotional video:
This creature is watching some kind of battle of the "gods". Equally interesting is that in this battle, as you can see, something resembling a setup with arrows or missiles. But as far as the telescope is concerned, about 1,000 years ago (the approximate age of the bas-reliefs), the telescope was not yet invented, according to official history.
At the same temple, but in a different place, you can see another interesting picture. These are more than 5 creatures dressed in one outfit, namely, something very similar to space suits. He is wearing a helmet on his head and this is obvious, and on his back there is something like a balloon.
And the most interesting thing is that this is not a fantasy, but a clear image of something that is not typical for the 10th century AD approximately.
As I said, most likely, you can see a lot more there, but I could only find information about these objects. And since I mentioned the cosmonaut, it is worth mentioning a separate cosmonaut figurine.
In Spain, in the city of Salamanca, there is a cathedral, which was built from the 15th to the 18th century approximately. On one of the walls, and high enough, they filmed a figure in the distinct image of an astronaut.
I must say right away that I am not stating that the figurine is ancient, it is just an interesting find, but there are some oddities. If the figurine was added during the restoration, as most people claim, then at least this was not documented anywhere. And the addition of such elements to a religious building, in theory, should be seriously punished.
In addition, when they say that it was definitely done during the restoration of the 90s, neither the name of the architect nor any other specialist is known. In general, maybe the figurine was added in our time, but there are many other "ancient cosmonauts", the same temple about which I told above, as well as many artifacts, drawings, etc.
Next is the Ta Prohm temple, which according to the official version was built in the 7th century. But on one of the walls, you can see the bas-reliefs of three strange creatures, one of which resembles a stegosaurus. Some claim that this is some kind of animal, and behind it are mountains, but this explanation is even more absurd than a dinosaur.
The problem is that in the 7th century, if only a small part of people knew about the existence of dinosaurs. In addition, the ancient people did not have the knowledge to restore the structure of this or that dinosaur and depict it in this form.
Well, at the end of the article, I will add a huge number of bas-reliefs around the world with unknown creatures and saucer-shaped flying vehicles, which many still record to this day.
In general, based on the bas-reliefs, one can draw only one conclusion that the ancient people knew a lot and all this does not fit into the official history at all.
Of course, you can look for excuses that somewhere is a fake, in another case a joke, and in the third it is an accident, but there cannot be so many coincidences. Therefore, it is worth seriously thinking about the past and what then unknown civilizations could see and live with.
