Abstract
The dome structure has been treated in two layers among the techniques that have formed the space in Baroque architecture and the light used to be manipulated to create the openness of space and the fantasy of atmosphere. Such an expression technique has influenced on the expression of space in the architecture of New York Five in the 1960s to 1970s and the concept of multiple space embellished with various layers has appeared in the architectural concept of New York Five; meanwhile, the common meaning with the technique of double layers and the ways of phenomenal expressions that have recognized the existence of space in the Baroque period has been achieved through the light, immaterial organism. It means that the existing concept of light limited simply to the plane elements of brightness and darkness has been treated as a formative element that has defined and adjusted the visual expansion and reduction of the space Itself and special existence and has been used as an element of the media of spatial structure. In addition, these elements have been treated as another solution for the emotional aspects of space. Therefore, this study compares the plastic and formative meaning of the Baroque architecture with that of New York Five in terms of the relation between space and light and examines them; in doing so, it will give a clue to understand various and new space expression techniques to many architects and space designers who have led modern architecture.
