Well said.
The Sassanids left such a mountain of knowledge and lore, not to mention bright, intelligent people, that the Muslims became associated with the forefront of knowledge for centuries. But in the end the culture of Islam won out. Persian art and knowledge devolved down to endless repetitive calligraphy and ugly fanaticism. A terrible tragedy.
Have you read the book by the Turk author Orhan Pamuk, “my name is Red”?
It’s a murder mystery but also a commentary on the proscription and destruction of realistic Middle Eastern art by the stylization ‘required’ by the Koran. The protagonist is an artist in Istanbul of the 1500s.
