The proscenium Arch is the arch or frame extending around the front of the stage of a theatre.
Anyway, I'm going to propose, him for the Stuyvesant and the proscenium.
The chief feat however is not yet performed, that which is to be acted in front of the proscenium!
c.1600, "stage of an ancient theater," from Latin proscaenium, from Greek proskenion "the space in front of the scenery," also "entrance of a tent," from pro "in front" (see pro-) + skene "stage, tent, booth" (see scene). Modern sense of "space between the curtain and the orchestra" is attested from 1807.
