This document summarizes Maeve Curley's dissertation on the experience of performers in arenas throughout history. It discusses the evolution of arenas from ancient Greek stadia to Roman amphitheaters to modern Spanish bullrings. The Greek stadia were simple running tracks that evolved to include seating areas. The Roman amphitheaters were influenced by Greek theaters and formed oval shapes to seat more spectators closer to performances involving gladiators. Finally, bullrings evolved from rectangular shapes to circular designs in Spain to create a unified audience experience and intimate atmosphere for bullfights. Throughout, the document examines the relationship between performers and audiences in shaping the design of arenas.
