The Large Theater in Pompeii was built in the usual Greek fashion which utilized the natural slopes of a hillside. Before Pompeii was destroyed the seats were numbered, with each person allowed 40 cm (15 3/4 inches). The theater could accommodate 5,000 people. An enormous cloth canopy was used to protect the audience from the sun and wind. This theater is occasionally used for performances today.
We know from Acts 19:29-41 that a disorderly gathering occurred in a similar theater in Ephesus when the silversmiths felt their idol-making trade was threatened by conversions to Christianity.
