Fivefold tunnel is a freestanding arched passageway that connects two ceremonial rooms of the enfilade, reminiscent of a baroque arcade, or traillage. Composed of intersecting sets of parallel steel bars, the latticework structure, whose pattern is based on Ammann lines, displays fivefold symmetry. Five sets of parallel lines, spaced according to the golden ratio, cross each other at angles of 108 and 72 degrees, generating a complex aperiodic pattern. The use of fivefold symmetry in this work stems from the artist’s close collaboration with Icelandic mathematician and architect Einar Thorsteinn.
