Demosthenes (384 BC - 322 BC) is generally considered the greatest of the Ancient Greek orators. His writtings provide an insight into the life and culture of Athens at this period of time. He suffered from a speech impediment and a common story tells of his talking around mouthfuls of rocks to improve his diction. He became a prominent political orator (speech-maker) making his living through his ability to write and make speeches. He is best known for his Philippic orations, urging the populace to rise up and defend their country against Philip II of Macedon, who was steadily gaining power and territory for the Macedonian state.
