In honor of the 100th anniversary of Philadelphia’s Benjamin Franklin Parkway, the NCSA committee invites proposals that explore the notion of the vista in the nineteenth century. From personal gardens to public parks, from the street level to the top of a skyscraper, or from the microscope to the panoramic photograph, the nineteenth century was a moment when the idea of the vista changed from a narrow sightline to a sweeping, expansive view. How did theorists alter our historical perspective, broadening our notion of the world through science or religion? In what ways did power systems affect urban vantage points? How did man-made vistas reflect socio-cultural ideals? How did domestic spaces or nightlife transform with the widespread use of gas or electric lighting? How does the conceptual vista operate metaphorically? Topics might include horticulture, landscapes and seascapes, new technology, photography, sightseeing, film and the theater, urban planning, visions and dreamscapes, shifting perceptions of the gaze, or literary or artistic descriptions or depictions of viewpoints. In contrast, papers may consider the absence of vistas, such as mental or physical confinement or elements that obfuscate a view.
