Ellen Lanyon's "Niagara" is a lithograph that reflects the artist's distinctive approach to rendering natural phenomena through a surrealist and imaginative lens. The work transforms the iconic waterfall into a dreamlike composition, characteristic of Lanyon's practice of combining realistic observation with fantastical elements and vibrant color. As a lithograph, the piece demonstrates the artist's masterful control of the medium to achieve both delicate detail and bold gestural marks.
