What is architecture without light? Our visual understanding of the world is defined through both material and light, but light is only revealed to the human eye through interactions with material, which in turn exists only in the presence of light, at least to the eye. This interdependence defines every visual environment we inhabit, From the Pantheon in Rome, with its single ceiling oculus that admits a dramatic beam of light from the heavens, to the High Line park in New York City, where discreet lighting fixtures make the ark appear to float over the city, light gives both exterior and interior spaces depth, atmosphere, and definition.
