The stage columns, like the Globe itself, are actually polygonal rather than perfectly round. Due to the sixteenth-century methods used in their construction, each is a 64-sided shape. *

Due to the sixteenth-century methods used in their construction, each Theater is a 64-sided shape.

Explanation:

Theater in the city of London had been a big affair in the time of Elizabeth and it was evident in the rather elaborate construction of its halls.

One can see even by the modern globe of the Shakespeare company that the space that is retained by the structure is polygonal.

This was because these theaters had been springing up from their previous less fortunate existence in tents so they had retained the design.

The structure was kept that way because the space did not need to be too symmetrical.

Then there's the whole cultural, social relativity thing. if the novel exemplifies cultural and social values that are part of america/americans, and details a setting that is part of america in a way only a citizen would know, then, its american literature.
