Fascinating to see so many examples of a Tetractys in #India. These are from roughly 200 AD. I have heard some theories that Pythagoras travelled to India and was given the title Pytha Guru there. Pythagoras popularised the symbol, yet it was a much more ancient symbol but it is very mysterious. Even Pythagoras had a secret society centered about the #Tetractys.
