The first and most considerable was properly called the scene, and gave its name to this whole division. It occupied the whole front of the building from side to side, and was the place allotted for the decorations. This front had two small wings at its extremity, from which hung a large curtain, that was let down to open the scene, and drawn up between the acts, when any thing in the representation made it necessary. The second, called by the Greeks indifferently προσκήνιον, and λοτεῖον and by the Romans _proscenium_, and _pulpitum_, was a large open space in front of the scene, in which the actors performed their parts, and which, by the help of the decorations, represented either a public square or forum, a common street, or the country; but the place so represented was always in the open air. The third division was a part reserved behind the scenes, and called by the Greeks παρασκήνιον. Here the actors dressed themselves, and the decorations were locked up. In the same place were also kept the machines, of which the ancients had abundance in their theatres. As only the porticoes and the building of the scene were roofed, it was necessary to draw sails, fastened with cords to masts, over the rest of the theatre, to screen the audience from the heat of the sun. But as this contrivance did not prevent the heat, occasioned by the perspiration and breath of so numerous an assembly, the ancients took care to allay it by a kind of rain; conveying the water for that use above the porticoes, which falling again in form of dew through an infinity of small pores concealed in the statues, with which the theatre abounded, did not only diffuse a grateful coolness all around, but the most fragrant exhalations along with it; for this dew was always perfumed. Whenever the representations were interrupted by storms, the spectators retired into the porticoes behind the seats of the theatre.
