The ancient Greek mathematician Pythagoras found that music followed mathematical principals. It only took us 2500 years to rediscover that connection. It is amazing how much knowledge the ancient Greeks and Egyptians and others knew that are lost to antiquity that we do not know today.
You can thank the Muslims for burning down the Library at Alexandria. It would have held a bounty of ancient knowledge lost to us today.
It was Umar the Muslim conqueror of Alexandria who said with the burning of the library - paraphrasing “ If its in the Koran we already have it, if its not we don’t want it!”
Technically speaking the library suffered fire damage from Julius Caesar’s occupation of Alexandria & from rioting between Christians & Jews during the reign of Theodosius I (roughly 400 AD).
