Dorothea Rockburne’s *On the Consideration of the Curve* surveys more than fifty years of abstraction in which mathematics and material are inseparable. Graphite-and-kraft-paper constructions from the late 1960s, Golden Section paintings, translucent vellum Angels inspired by Giotto, and later works on paper take shape through folding, cutting, layering, and measuring, exploring topology, proportion, and perception.
