disagree. Central Asia golden age was nuked by Mongels. Islamic golden age is another location - Iraq.
Khurasan, Bactria, Sogdiana very important regions for Central Asia. Susiana and Mesopotamia - another place.
ok ok Prof. Starr! but my tastes run toward thinking pre-Islamic C. Asia (especially under Sassanids) is more underrated !
there was a lot of human capital in Khurasan region during the Central Asian enlightenment. totally separate from Mid East.
well Chaney's pre-1500 data seem to agree with your assessment (white circles scientific production, grey=overall book prod)pic.twitter.com/Lw7cIAZwHE
this chart also identifies Iberia as another, separate center. I love the fact it looks like an earthquake map.
anyway Chaney presents evidence that scientific decline spreads from East to West
