Historical Note on The Sand-Reckoner by Archimedes

The Sand-Reckoner by Archimedes was addressed to King Gelon of Syracuse (who appears to have lived some $250$ years earlier).

It is in this book that we learn that Aristarchus of Samos had first proposed a heliocentric universe, nearly $2000$ years before Nicolaus Copernicus.
