Reminds me of the Wootz Steelmaking (and much else) in classical India which was lost during the period of Anglo-Islamic colonization. Roman empire, Egypt and Greece, IMO is, contrary to current myths, is far closer in spirit to India than to anything of the 'modern West'. Indeed, the Greeks ruled parts of India for many centuries, and Rome had a great amount of trade with it.
The loss of so much rich tradition across the world due to birth of religion and its obsession with tyrannical power over everything is such a tragedy on humankind... this was recognized by the thinkers of Europe during the wee end of the 'renaissance', but in light of post-WW2 plebification of intellectuals, is being rolled back because of the current crop's moronic obsession with another religion: Marxism.
Such tragedy. tck. Such tragedy.
