Final answer:
The four pillars mentioned might symbolically or practically support drama performances, akin to how Pillars of Ashoka conveyed messages or the Greek skene used pillars to indicate stage entrances.
Step-by-step explanation:
The four pillars in the auditorium of Indian drama do not directly correspond to a known historical or architectural feature related to Indian drama specifically. However, pillars in ancient and classical structures often carried symbolic or practical functions. For example, the Pillars of Ashoka in ancient India were erected by Emperor Ashoka to disseminate his policies and teachings on morality throughout the Mauryan Empire.
In the context of classical Indian theatre, structural elements like pillars could be interpreted as part of the stage design or used to support structures where dramas were performed. In the realm of Greek theatre, pillars played a critical role as part of the skene, indicating different entrances for actors. These pillars, especially when used in liturgical drama, could have delineated specific staging areas known as 'mansions' that represented various settings within narratives.
