In the Heraklion Archaeological Museum, in Greece, there is an interesting exhibit in the form of a rectangular slab of regular shape with identical circular notches or depressions, you can call it whatever you want.
And everything would be fine if not the material of this artifact, namely basalt. Besides this, the artifact itself is estimated to be
4000 years old. Although the artifact itself looks strange, in fact, it is extremely difficult to make such things with primitive tools, given that it was created many thousands of years ago.
This raises many questions, but no less interesting is the purpose of the artifact, especially if its processing was almost impossible without technology.
