The Victorian age was the last great age before this knowledge was banned. This knowledge (of harmonic things like archecture, sound, light, etc) happened to be banned starting from around the time of the federal reserve.

Notice that architecture today is generally what i describe as 'non-harmonic', and is visually ugly and makes you feel confused. Harmonic architecture reaches its pinnacle in something like a great cathedral.

Tartaria IS a psyop to distract from the fact that this knowledge has been purposefully obscured, and to stop people from reviving this knowledge. Researching about the Tatars will get you nowhere, if you truly want to understand about what makes these buildings (and their construction techniques.....) special.
