More than 2,500 years ago, an Athenian nobleman named Cylon -- the first recorded Olympic champion -- tried to take over the city of Athens and install himself as its sole ruler. According to Thucydides and Herodotus, Athenian and Greek historians who wrote about the coup, Cylon enticed an army of followers to enter the city and lay siege to the Acropolis. Now archaeologists in Athens believe they may have found some of the remains of Cylon's army in a mass grave in Phaleron, four miles (6 kilometres) south of downtown Athens.
