On the stage. The history of the theater

The performance will begin soon. People are in a hurry to the theater. Someone from work, someone is from home, and someone even from another city, if the performance is especially interesting. So they hand over clothes and things to the wardrobe, take binoculars if the places are far from the stage, and go into the hall. No magic, right?
But the light goes out and the curtain rises, and silence reigns in the full hall - tense, tight, ringing. Not at all the same as it happens in an empty room. This is the silence of unity, when for those who are on stage and those who sit in chairs, there is nothing more important than what is happening in this second. Here it is, the real magic of the theater. For this, it exists.
Let"s talk about the theater, about its structure and history. How did the theater begin and how did it change over time? What types of art did he unite in himself and what forms took? Why does the theater live and develop more than 2000 years?
The third call sounded. The light goes out. We begin!
