They have these stone megaphones that you could speak into that projected your voice across the archeological campus to the other side where someone listening into a similar stone piece could hear you. They built this approximately 1,500 years before Christ. I wouldn’t be able to build two stone voice projection devices right now if you paid me. Perhaps two styrofoam cups with a string, maybe a long long string.
