At the annual Athenian 
 drama festival in 426 BC,
  a comic play called The Babylonians,
  written by a young poet 
 named Aristophanes,
  was awarded first prize.
  But the play’s depiction of Athens’ 
 conduct during the Peloponnesian War
  was so controversial that afterwards,
  a politician named Kleon 
 took Aristophanes to court
  for "slandering the people of Athens 
 in the presence of foreigners."
  Aristophanes struck back two years later
 with a play called The Knights.
  In it, he openly mocked Kleon,
  ending with Kleon’s character working as 
 a lowly sausage seller
  outside the city gates.
  This style of satire was a consequence
  of the unrestricted democracy 
 of 5th century Athens
  and is now called "Old Comedy."
  Aristophanes’ plays, the world’s earliest 
 surviving comic dramas,
  are stuffed full of parodies, songs, 
 sexual jokes, and surreal fantasy.
  They often use wild situations,
  like a hero flying to heaven 
 on a dung beetle,
  or a net cast over a house to keep 
 the owner’s father trapped inside,
  in order to subvert audience expectations.
  And they’ve shaped how comedy’s
 been written and performed ever since.
  The word "comedy" comes from 
 the Ancient Greek "komos," – revel,
  and "oide," – singing,
  and it differed from its companion 
 art form, "tragedy" in many ways.
  Where ancient Athenian tragedies dealt 
 with the downfall of the high and mighty,
  their comedies usually ended happily.
  And where tragedy almost always 
 borrowed stories from legend,
  comedy addressed current events.
  Aristophanes’ comedies celebrated ordinary
 people and attacked the powerful.
  His targets were arrogant politicians,
  war-mongering generals,
  and self-important intellectuals,
  exactly the people who sat in 
 the front row of the theatre,
  where everyone could see their reactions.
  As a result, they were referred to 
 as komoidoumenoi:
  "those made fun of in comedy."
  Aristophanes’ vicious 
 and often obscene mockery
  held these leaders to account,
 testing their commitment to the city.
  One issue, in particular, 
 inspired much of Aristophanes’ work:
  the Peloponnesian War 
 between Athens and Sparta.
  In Peace, written in 421 BC,
  a middle-aged Athenian frees 
 the embodiment of peace from a cave,
  where she’d been exiled 
 by profiteering politicians.
  Then, in the aftermath of a crushing 
 naval defeat for Athens in 411 BC,
  Aristophanes wrote "Lysistrata."
  In this play, the women 
 of Athens grow sick of war
  and go on a sex strike 
 until their husbands make peace.
  Other plays use similarly fantastic 
 scenarios to skewer topical situations,
  such as in "Clouds,"
  where Aristophanes mocked 
 fashionable philosophical thinking.
  The hero Strepsiades enrolls in
 Socrates’s new philosophical school,
  where he learns 
 how to prove that wrong is right
  and that a debt is not a debt.
  No matter how outlandish these plays get,
 the heroes always prevail in the end.
  Aristophanes also became
 the master of the parabasis,
  a comic technique where actors 
 address the audience directly,
  often praising the playwright 
 or making topical comments and jokes.
  For example, in "Birds,"
  the Chorus takes 
 the role of different birds
  and threatens the Athenian judges that
 if their play doesn’t win first prize,
  they’ll defecate on them 
 as they walk around the city.
  Perhaps the judges 
 didn’t appreciate the joke,
  as the play came in second.
  By exploring new ideas
  and encouraging self-criticism 
 in Athenian society,
  Aristophanes not only 
 mocked his fellow citizens,
  but he shaped the nature of comedy itself.
  Hailed by some scholars 
 as the father of comedy,
  his fingerprints are visible 
 upon comic techniques everywhere,
  from slapstick
  to double acts
  to impersonations
  to political satire.
  Through the praise of free speech 
 and the celebration of ordinary heroes,
  his plays made his audience think 
 while they laughed.
  And his retort to Kleon in 425 BC 
 still resonates today:
  “I’m a comedian, 
 so I’ll speak about justice,
  no matter how hard 
 it sounds to your ears.”
