Sri. Biswa, Greetings. I did not talk about the contents of Alexandria library. It would have contained amoung other languages, Arabic and Sanskrit too. I mentioned about Nalanda library too. Arabic was flourishing before Muhammad too. Persian literature was great too from what the Iranians say. Where ever they set foot after invading various countries, the literature in those countries burned. In Arabia, pre-Islamic literature burned too. That was my point. Cheers!
