• Performance theory and semiotics unify theatre studies from ancient to early modern stages, foregrounding staging language, disguise, identity, and ritual as interpretive keys across Greek tragedy, medieval drama, and Shakespearean theatre [5], [4], [19], [12], [14], [1].

• A historical-methodology pattern situates theatre within shifting social structures, court culture, and audience expectations across medieval, Jacobean, and Roman contexts, revealing how performance embodies power, ritual, and sociopolitical change [3], [1], [13], [15], [9], [11].

• Archaeology and architectural analysis anchor theatre history in material space, as excavations, buildings, and artifacts illuminate theatres, amphitheatres, and stage spaces, revealing constraints and opportunities shaping performance [6], [10], [20], [16], [8], [18].

• Cross-period comparative frames treat drama as adaptation, reception, and worldview from Euripidean perspectives through Terence, medieval liturgy, and Jacobean drama, emphasizing continuities and shifts in dramatic practice [11], [14], [15], [13], [1].
