Archimedes of Syracuse was an ancient astronomer, war planner, engineer, astrologer and mathematician whose works are mostly lost because of the tragic fire Cleopatra set to the Library of Alexandria, a ruse permitting her time to drown her baby brother, a usurper of Macedonian rule in Polemic Egypt. The fire destroyed the libraries collection of ancient works only known to us today by reference from surviving relics or papyri.
In the early 20th century, researchers in Istanbul discovered Archimedes' work re-written on a prayer book.
This is story of the ancient world's greatest scientific mind: Archimedes of Syracuse.
