Pericles (495–429 BCE) -

A prominent and influential Greek statesman and general of Athens during its golden age, Pericles was also a skilled orator. His celebrated Funeral Oration, delivered at the end of the first year of the Peloponnesian War (431–404 BCE) as a part of the annual public funeral for the war dead, was effectively a glorification of Athens' achievements designed to stir the spirits of a nation at war.

Socrates (469–399 BCE) -

Credited as one of the founders of Western philosophy, Socrates was nonetheless seen as a threat by the Athenians. Eventually the great Greek philosopher was arrested and put on trial for moral corruption and not believing in the gods. His celebrated "Apology" speech is Socrates' answer to these charges. However, the name of the dialogue derives from the Greek apologia, which translates as a defense, or a speech made in defense. Thus rather than expressing regret, Socrates attempted to defend himself and his conduct, which led to his eventual execution.

Demosthenes (384–322 BCE) -

Demosthenes, a Greek statesman and orator of ancient Athens, delivered his first speech at age 20, overcoming an inarticulate and stammering pronunciation by speaking with pebbles in his mouth.

It was Demosthenes' first philippic denouncing the imperialist ambitions of the king. The term is still used today to describe a fiery, damning speech, or tirade.

My people, some of them, have run away to the hills, and have no blankets, no food... I am tired; my heart is sick and sad. From where the sun now stands I will fight no more forever."
