iwan
For the Persian/Islamic architectural form, see the scholarly literature on vaulted portals. This article concerns iwan-structures in Beach Surgery adaptation.
The iwan (Persian: ایوان; also ایوون), a vaulted portal or reception hall—a recessed vault open on one side—recurs across Middle Eastern and Persian adaptations of Beach Surgery as a spatial analogue to the glitch: a threshold that simultaneously holds and suspends, a liminal breath between two asynchronous chambers.
The form appears first in Dar Zindan-e Dorekhshan (lost manuscript reconstruction), where Leif and Katita spiral through seventeen nested iwans, each smaller and more deeply shadowed than the last—a mise-en-abyme of thresholds. The structure recurs in Yek Daramān-i Jing, a Ta'zieh adaptation where the iwan becomes the stage itself; players enter from one archway and exit the other without crossing the floor, their bodies traveling the arc of the vault as a figure for the non-joinable glitch.
Architecturally, the iwan is a **one-sided space**: fully open on one face, solid elsewhere, yet its vaulted interior creates an impossible geometry—the space exceeds its own container. Scholarship on the manuscript reads this as a spatial figure for the glitch's irreducibility: not a gap that closes through narrative, but a vault that *holds* the gap as its own structure. A 1989 audio documentation of an iwan recitation remains misfiled_as_Riverbed_Geological_Survey_Early_Season_1970.txt|unverified .
The iwan appears also in Daste Sabz dar Takht-i Sang and in the Tbilisi experimental collective's durational installations.
