Tragedy. (I) Tragedy in greece originated in the lyric dithyramb; i.e. in the song of a chorus at the rites held in honour of Dionysus. This song, in accordance with the cult of the god, expressed at one time exuberant joy, at another deep sorrow. The cult of Dionysus is also indicated by the Tery name of tragedy, signifying goat-song; i.e. (according to the usual explanation) the hymn sung by the chorus in their dance round the altar at the sacrifice of the goat, which was dedicated to Dionysus. Others derive the name from the fact that, to represent Satyrs, the chorus were clad in goatskins, and hence resembled goats. These choral songs seem to have received a certain dramatic form as early as the time of ArtOn, to whom the dithyramb owes its artistic development. The true drama, including tragic and satyric plays, was evolved subsequently in Athens.
| of Icarla, which was a chief seat of the cult of Dionysus. The date assigned to this is
! 540 B.C. Thespis was at the same time poet, leader of the chorus, and actor. According
| to the testimony of the ancients, his pieces
' consisted of a prologue, a series of choral songs, standing in close connexion with the action, and dramatic recitations introduced between the choruses. These recitations were delivered by the leader of the chorua, and were partly in the form of monologues, partly in that of short dialogues with the chorus, whereby the action of the play was advanced. The reciter was enabled to appear in different mles by the aid of linen or wooden masks. These also are said to have been contrived by the poet himself. The invention of Thespis, whose own pieces soon lapsed into oblivion, won the favour of Plsistratus and the approval of the Athenian public. Tragedy thus became a substantial element in the Attic festival of Dionysus. Thespis' immediate followers were Ctuerilus, Pratlnas (the inventor of the satyric drama), his son Aristids, and Phri/nlchus. Phrynichus especially did good service towards the development of tragedy by introducing an actor apart from the leader of the chorus, and so preparing the way for true dialogue. He further improved the chorus, which still, however, occupied a disproportionate space in comparison with the action of the play.
Tragedy was really brought into being by sEschyhts, when he added a second actor (called the deutlragonistes) to the first, or protaganistes, and in this way rendered dialogue possible. He further subordinated the choruses to the dialogue.
SGphdcle's, in whom tragedy reaches its culminating point, added to jEschylus' two actors a third,OTtrltagonistes; and jEschylus accepted the innovation in his later plays. Thenceforward three actors were regularly granted by lot to each poet, at the public expense. Only rarely, and in exceptional cases, was a fourth employed. Sophocles also raised the number of the chorus from twelve to fifteen. The only other important innovation due to him was, that he gave up the internal connexion, preserved by jEschylus, among the several plays of a tetralogy which were presented in competition by the tragic poets at the festival of Dionysus.
