A poem can be read alone in a room. A play is unfinished until someone stands up and speaks it. Drama is literature written to be performed by actors before an audience, and that fact shapes everything about it: dialogue instead of description, scenes instead of chapters, and the audience's shared breath in a dark space. Three great traditions show how differently cultures have used the stage.

Greek tragedy

Tragedy took shape in Athens in the sixth and fifth centuries BCE. Plays were staged at the City Dionysia, a spring festival in honor of the god Dionysus, where playwrights competed for a prize before thousands of citizens in an open air theater. Actors wore masks, and all of them were men. Alongside the actors was the chorus, a group of performers who sang and danced and commented on the action, often voicing the worries of ordinary citizens. Only about thirty complete tragedies survive, by three authors: Aeschylus, Sophocles and Euripides.

Sophocles' Antigone, from around 441 BCE, is one of the most argued over plays ever written. After a civil war, King Creon forbids anyone to bury the rebel Polynices. His sister Antigone buries him anyway. Facing Creon, she says, in R. C. Jebb's 1891 translation, that she did not think his decrees "were of such force, that a mortal could override the unwritten and unfailing statutes of heaven." Antigone dramatizes the conflict between a ruler's law and a higher moral duty. The play does not make Creon a cartoon: he speaks for order in a city just torn by war. The philosopher Hegel later read it as a clash between two rightful claims, and readers since have used it to think about conscience and civil disobedience.

Shakespeare

William Shakespeare (1564 to 1616) wrote or helped write about 38 plays for London's public theaters, including the Globe, built in 1599. His theater mixed kings and clowns, murder and jokes, often in the same scene. Much of his dialogue is in blank verse: unrhymed lines of iambic pentameter, ten syllables with the stress on every second one, a rhythm close to natural English speech. His most famous device is the inward speech. A soliloquy is a speech in which a character alone on stage speaks their thoughts aloud, as when Hamlet weighs whether "to be, or not to be."

Shakespeare gave voice to outsiders even when his culture despised them. In The Merchant of Venice, Shylock, a Jewish moneylender, asks, "Hath not a Jew eyes?" The play still sparks debate over whether it exposes or repeats the prejudice of its time. We have many of these plays only because of luck and loyalty. Seven years after his death, two fellow actors gathered his work into the First Folio of 1623, and the First Folio saved about eighteen plays that had never been printed, among them Macbeth and The Tempest.

Noh

In Japan, a very different theater took shape in the fourteenth century. Noh was developed by the actor Kan'ami and his son Zeami, who won the patronage of the shogun Ashikaga Yoshimitsu. A Noh stage is nearly bare, with a painted pine tree on the back wall. The main actor wears a carved wooden mask; a chorus chants, and flute and drums accompany slow, highly controlled movement. Many plays follow a pattern: a traveling monk meets a local person who turns out to be a ghost, and the ghost relives the moment that still binds it to the world. Zeami wrote treatises on acting, and Zeami prized yugen, a quality of subtle, mysterious grace, above surface excitement. Comic plays called kyogen were performed between Noh pieces to relieve the mood.

India had its own classical drama, written in Sanskrit. Kalidasa's Shakuntala, probably from the fourth or fifth century CE, so impressed European readers after William Jones translated it into English in 1789 that Goethe praised it in verse.

Worked example: two ghosts

Compare the ghost in Hamlet with the ghost in the Noh play Atsumori, by Zeami. Hamlet's father appears in armor and demands revenge for his murder. His command drives the whole plot forward, and nearly everyone is dead by the end. In Atsumori, the warrior Kumagai has become a monk after killing Atsumori, a sixteen year old noble, at the battle of Ichi-no-Tani in 1184. He returns to pray for the boy. Atsumori's ghost appears, relives the battle and raises his sword against his killer. Then he stops, recognizing that the monk's prayers have made them friends, not enemies.

Read closely, the two ghosts point in opposite directions. Hamlet's ghost binds the living to the past; Atsumori's ghost is released from it. One play explores how revenge spreads from person to person; the other imagines how prayer and remorse can end a cycle of killing. Neither is simply better. Together they show that the stage can be a place to rehearse a society's answers to violence, and that a slow form like Noh can carry as much moral weight as a play full of swordfights.
