There are many mysteries around or the historians are trying to hide the truth. Like Graham Hancock said...

When I saw the columns and triumph arcs in Rome, depicting dacian kings and warriors, I asked myself: from so many great nations that romans conquered, why they bother to put these dacians on their temples ?

Then from the so many other nations, why the dacians later became the romanians ? Romans - Romanians ? Strange coincidences, right?

So many mysteries...
