Another distinctive aspect of Fitzgerald¹s earlier work, and one that is still important to his works today, is his use of line. Whether it is the direct linear components of line in planes, contour of actual or implied mass, geometric shape, negative shapes, or implied line through composition, Fitzgerald taps into the deeper expressive power of line. It is his mastering of line in composition that sets his work apart from that of other sculptors. It is not just the expressive quality of line that he is interested in- it is the cognitive, connotative symbolic geometry, sheer written language, and numbers that line embodies in relationship to knowledge. "It is not just the visual line; it is the things that line connotes".
