What kind of props and scenery were used?

Minimal Scenery and Props were used. Actors wore masks, platform shoes and elongated togas with high waistbands.

The actors were so far away from the audience that they had to make their masks extremely vibrant and also made them a little bit unrealistic. (CrystaLinks)

Lighting was mainly provided by the sun besides torches that were used as props to play up the essence of certain characters. The principal traits of the characters portrayed could be expressed in the mask, and a simple convention arose whereby types of character had their own types of mask. (Ancient Greek Drama and Theatre)

On the platform that was the stage there was a small hut that was used as a building actors could walk in and out of from the door in the front. When a famous writer painted the front of the building with a nature scene the invention of scenery on stage was created. (BBC)
