These landscapes contain all the elements of her huge originality; the spontaneous brush strokes, the inventive shapes, lambent color, and monumental scale of work and vision. Mahoney's distinctive style that bridges realism and abstraction uses color and structure to share with the viewer the spiritual content of experiencing the miracle of nature and life.
