The invisible enemy was
the Plague of Athens, an epidemic that possibly reached from Africa to
the city of Athens, during the Peloponnesian War, at a time when the
Greeks could still win the war. Experts think that the
plague, often identified as Bubonic Plague (although in recent studies
it is thought that it was a hemorrhagic fever, or perhaps Typhus)
entered the city-state of Athens through the port of Piraeus, its only
source of food and supplies. Due to the lack
of hygiene at that time, Athens became a propitious place of the palga,
killing many Greeks, even General Pericles, who was a great Greek
statesman, passed away after the death of his wife and children
Xanthippus and Paralus. The plague of Athens finally decided the course of the Peloponnesian War.
