Here are descriptions of the two artworks: 1. Parallel Lines by Ann Hamilton is a mixed media installation presented in two separate rooms as part of the 1991 Sao Paulo Biennial art exhibition in Brazil. It likely featured found objects and textiles arranged in a way to divide and connect the two spaces. The title references the parallel nature of the two parts existing simultaneously but separately. 2. The Basilica of Hagia Sophia is a 6th century church located in Istanbul, Turkey that was originally constructed as an Orthodox Christian cathedral but now serves as a museum. Notable for its massive dome structures, it exemplifies the architectural achievements and mathematical/engineering principles of Byzantine building techniques during the early Christian period.
