Gorham Phillips Stevens was director of the American School of Classical Studies in Athens during World War II and was key as both an architect and archaeologist in the first reconstruction of the Erechtheon in Athens This paper reflects an early stage in the reconstruction project and argues that the East wall had windows by which the inner cella was lit. This extra lighting suggests the use of the space as a sacred art gallery as well as a shrine. The paper is important in understanding the subtle art of reconstructing ancient ruins and illuminates the process by which the first Acropolis restoration (which is now being revised and corrected) was accomplished.
