2. Origins of Greek Drama 
Ancient Greeks from the 5th century BC onwards were fascinated by the question of the origins of tragedy and comedy. They were unsure of their exact origins, but Aristotle and a number of other writers proposed theories of how tragedy and comedy developed, and told stories about the people thought to be responsible for their development. Here are some excerpts from Aristotle and other authors which show what the ancient Greeks thought about the origins of tragedy and comedy.
Aristotle on the origins of Tragedy and Comedy
1. Indeed, some say that dramas are so called, because their authors represent the characters as "doing" them (drôntes). And it is on this basis that the Dorians [= the Spartans, etc.] lay claim to the invention of both tragedy and comedy. For comedy is claimed by the Megarians here in Greece, who say it began among them at the time when they became a democracy [c. 580 BC], and by the Megarians of Sicily on the grounds that the poet Epicharmas came from there and was much earlier than Chionides and Magnes; while tragedy is claimed by certain Dorians of the Peloponnese. They offer the words as evidence, noting that outlying villages, called dêmoi by the Athenians, are called kômai by them, and alleging that kômôdoi (comedians) acquired their name, not from kômazein (to revel), but from the fact that, being expelled in disgrace from the city, they wandered from village to village. The Dorians further point out that their word for "to do" is drân, whereas the Athenians use prattein. (Aristotle: Poetics Chapter 3)
2. And in accordance with their individual types of character, poetry split into two kinds, for the graver spirits tended to imitate noble actions and noble persons performing them, and the more frivolous poets the doings of baser persons, and as the more serious poets began by composing hymns and encomia, so these began with lampoons....Thus among the early poets, some became poets of heroic verse and others again of iambic verse. Homer was not only the master poet of the serious vein, unique in the general excellence of his imitations and especially in the dramatic quality he imparts to them, but was also the first to give a glimpse of the idea of comedy [in the Margites]...And once tragedy and comedy had made their appearance, those who were drawn to one or the other of the branches of poetry, true to their natural bias, became either comic poets instead of iambic poets, or tragic poets instead of epic poets because the new types were more important-- i.e. got more favorable attention, than the earlier ones. Whether tragedy has, then, fully realized its possible forms or has not yet done so is a question the answer to which both in the abstract and in relation to the audience [or the theater] may be left for another discussion. Its beginnings, certainly, were in improvisation [autoschediastikês], as were also those for comedy, tragedy originating in impromptus by the leaders of dithyrambic choruses, and comedy in those of the leaders of the phallic performances which still remain customary in many cities. Little by little tragedy grew greater as the poets developed whatever they perceived of its emergent form, and after passing through many changes, it came to a stop, being now in possession of its specific nature [tên hautês phusin]. It was Aeschylus who first increased the number of the actors from one to two and reduced the role of the chorus, giving first place to the dialogue. Sophocles [added] the third actor and [introduced] painted scenery. Again, [there was a change] in magnitude; from little plots and ludicrous language (since the change was from the satyr play), tragedy came only late in its development to assume an air of dignity, and its meter changes from the trochaic tetrameter to the iambic trimeter. Indeed, the reason why they used the tetrameter at first was that their form of poetry was satyric [i.e. for "satyrs"] and hence more oriented toward dancing; but as the spoken parts developed, natural instinct discovered the appropriate meter, since of all metrical forms the iambic trimeter is best adapted for speaking. (This is evident, since in talking with one another we very often utter iambic trimeters, but seldom dactylic hexameters, or if we do we depart from the tonality of normal speech. Again, [there was a change] in the number of episodes -- but as for this and the way in which reportedly each of the other improvements came about, let us take it all as said, since to go through the several details would no doubt be a considerable task. (Aristotle: Poetics Chapter 4)
Stories about the poet Arion
3. Periander was tyrant of Corinth. The Corinthians say (and the Lesbians agree) that the greatest wonder in his life was the voyage of Arion of Methymna to Taenarum on a dolphin. He was a kitharode second to none at that time and the first of men whom we know to have composed the dithyramb and named it and produced it in Corinth. (Herodotus I.23)
4. Arion, of Methymna...is said also to have invented the tragic mode (tragikoû tropou) and first composed a stationary chorus and sung a dithyramb and named what the chorus sang and introduced satyrs speaking verses. (The Suda lexicon)
5. Pindar says the dithyramb was discovered in Corinth. The inventor of the song Aristotle calls Arion. He first led the circular chorus. (Proculus, Chrest. xii)
6. The first performance of tragedy was introduced by Arion of Methymna, as Solon said in his Elegies. Charon of Lampsacus says that drama was first produced at Athens by Thespis. (John the Deacon, Commentary on Hermogenes)
Stories about Cleisthenes, Sicyon, and Hero-drama
7. I must not omit to explain that [the tyrant] Cleisthenes picked on Melanippus as the person to introduce into Sicyon, because he was a bitter enemy of Adrastus, having killed both Mecistes, his brother, and Tydeus his son-in-law. After settling him in his new shrine, he transferred to him the religious honors of sacrifice and festival which had previously been paid to Adrastus. The people of Sicyon had always regarded Adrastus with great reverence, because the country had once belonged to Polybus, his maternal grandfather, who died without an heir and bequeathed the kingdom to him. One of the most important of the tributes paid him was the tragic chorus, or ceremonial dance and song, which the Sicyonians celebrated in his honor; normally, the tragic chorus belongs to the worship of Dionysus; but in Sicyon it was not so -- it was performed in honor of Adrastus, treating his life-story and sufferings. Cleisthenes, however, changed this: he transferred the choruses to Dionysus, and the rest of the ceremonial to Melanippus. (Herodotus V.67)
Stories trying to explain why, if tragedy originated from Dithyrambs sung in honor of Dionysus, not all tragedies were about Dionysus ("Nothing to do with Dionysus": (ouden pros ton Dionuson)
8. When Phrynichus and Aeschylus developed tragedy to include mythological plots and disasters, it was said, "What has this to do with Dionysus?" (Plutarch, Symp. Quaest.)
9. Nothing to do with Dionysus. When, the choruses being accustomed from the beginning to sing the dithyramb to Dionysus, later poets abandoned this custom and began to write "Ajaxes" and "Centaurs". Therefore the spectators said in joke, "Nothing to do with Dionysus." For this reason they decided later to introduce satyr-plays as a prelude, in order that they might not seem to be forgetting the god. (Zenobius V.40)
10. Nothing to do with Dionysus. When Epigenes the Sicyonian made a tragedy in honor of Dionysus, they made this comment; hence the proverb. A better explanation: Originally when writing in honor of Dionysus they competed with pieces which were called satyric. Later they changed to the writing of tragedy and gradually turned to plots and stories in which they had no thought for Dionysus. Hence this comment. Chamaeleon writes similarly in his book on Thespis. (The Suda lexicon)
Stories about Thespis the Athenian playwright
11. From when Thespis the poet first acted, who produced a play in the city and the prize was a goat... (Marmor Parium, under the year about 534 BC).
12. This is Thespis, who first moulded tragic song, inventing new joys for his villagers, when Bacchus led the wine-smeared (?) chorus, for which a goat was the prize (?) and a basket of Attic figs was a prize too. The young change all this. Length of time will discover many new things. But mine is mine. (Dioscorides, Anth. Pal. VII. 410)
13. The unknown poetry of the tragic Muse Thespis is said to have discovered and to have carried poems on wagons, which they sang and acted, their faces smeared with wine-lees. (Horace, Ars Poetica 275-277)
14. As of old tragedy formerly the chorus by itself performed the whole drama and later Thespis invented a single actor to give the chorus a rest and Aeschylus a second and Sophocles a third, thereby completing tragedy... (Diogenes Laertius III. 56)
15. Thespis: Of the city of Ikarios in Attica, the sixteenth tragic poet after the first tragic poet, Epigenes of Sicyon, but according to some second after Epigenes. Others say he was the first tragic poet. In his first tragedies he anointed his face with white lead, then he shaded his face with purslane in his performance, and after that introduced the use of masks, making them in linen alone. He produced in the 61st Olympiad (536/5-533/2 BC). Mention is made of the following plays: Games of Pelias or Phorbas, Priests, Youths, Pentheus. (The Suda lexicon)

3. Staging an ancient Greek play
Attending a tragedy or comedy in 5th century BC Athens was in many ways a different experience than attending a play in the United States in the 20th century. To name a few differences, Greek plays were performed in an outdoor theater, used masks, and were almost always performed by a chorus and three actors (no matter how many speaking characters there were in the play, only three actors were used; the actors would go back stage after playing one character, switch masks and costumes, and reappear as another character). Greek plays were performed as part of religious festivals in honor of the god Dionysus, and unless later revived, were performed only once. Plays were funded by the polis, and always presented in competition with other plays, and were voted either the first, second, or third (last) place. Tragedies almost exclusively dealt with stories from the mythic past (there was no "contemporary" tragedy), comedies almost exclusively with contemporary figures and problems.
In what follows, we will run through an imaginary (but as far a possible, accurate) outline of the production of a Greek tragedy in 5th century BC Athens from beginning to end. The outline will bring out some of the features of creating and watching a Greek tragedy that made it a different process than it is today. Staging a play.

4. Greek Theaters

Greek tragedies and comedies were always performed in outdoor theaters. Early Greek theaters were probably little more than open areas in city centers or next to hillsides where the audience, standing or sitting, could watch and listen to the chorus singing about the exploits of a god or hero. From the late 6th century BC to the 4th and 3rd centuries BC there was a gradual evolution towards more elaborate theater structures, but the basic layout of the Greek theater remained the same. The major components of Greek theater are labled on the diagram above.
Orchestra: The orchestra (literally, "dancing space") was normally circular. It was a level space where the chorus would dance, sing, and interact with the actors who were on the stage near the skene. The earliest orchestras were simply made of hard earth, but in the Classical period some orchestras began to be paved with marble and other materials. In the center of the orchestra there was often a thymele, or altar. The orchestra of the theater of Dionysus in Athens was about 60 feet in diameter.
Theatron: The theatron (literally, "viewing-place") is where the spectators sat. The theatron was usually part of hillside overlooking the orchestra, and often wrapped around a large portion of the orchestra (see the diagram above). Spectators in the fifth century BC probably sat on cushions or boards, but by the fourth century the theatron of many Greek theaters had marble seats.
Skene: The skene (literally, "tent") was the building directly behind the stage. During the 5th century, the stage of the theater of Dionysus in Athens was probably raised only two or three steps above the level of the orchestra, and was perhaps 25 feet wide and 10 feet deep. The skene was directly in back of the stage, and was usually decorated as a palace, temple, or other building, depending on the needs of the play. It had at least one set of doors, and actors could make entrances and exits through them. There was also access to the roof of the skene from behind, so that actors playing gods and other characters (such as the Watchman at the beginning of Aeschylus' Agamemnon) could appear on the roof, if needed.
Parodos: The parodoi (literally, "passageways") are the paths by which the chorus and some actors (such as those representing messengers or people returning from abroad) made their entrances and exits. The audience also used them to enter and exit the theater before and after the performance.

5. Structure of the plays The basic structure of a Greek tragedy is fairly simple. After a prologue spoken by one or more characters, the chorus enters, singing and dancing. Scenes then alternate between spoken sections (dialogue between characters, and between characters and chorus) and sung sections (during which the chorus danced). Here are the basic parts of a Greek Tragedy:
a. Prologue: Spoken by one or two characters before the chorus appears. The prologue usually gives the mythological background necessary for understanding the events of the play.
b. Parodos: This is the song sung by the chorus as it first enters the orchestra and dances.
c. First Episode: This is the first of many "episodes", when the characters and chorus talk.
d. First Stasimon: At the end of each episode, the other characters usually leave the stage and the chorus dances and sings a stasimon, or choral ode. The ode usually reflects on the things said and done in the episodes, and puts it into some kind of larger mythological framework.
For the rest of the play, there is alternation between episodes and stasima, until the final scene, called the...
e. Exodos: At the end of play, the chorus exits singing a processional song which usually offers words of wisdom related to the actions and outcome of the play.
