While the A type cavea plan was created around the middle of the first century B.C. in Latium or Campania, B type was formed in Central Italy, including Latium, in the third quarter of the same century (Table 1). In the early Augustan age, C type appeared, probably in Roman colonies. Although B and C types were only used in Roman West Mediterranean cities, A type is found in more than half of all ‘ Roman-typed theatres ’ throughout the ancient Mediterranean world in the Roman period making it the most common cavea plan in those theatres.
