Okay. I’m sure anything I could provde wouldn’t be enough anway.
I have read extensively - This theory is something you hold dear but it is your own. I have never read any such claim that the Greek key or any architectural motif came from Indians to the Greeks. In fact it is impossible because this was an era before pictures - the Greek style was imported into India directly by stonemasons who were there due to Alexander. And of course the Greek key existed before that.
