James Howell (1935-2014) was an American abstract artist who used infinite variations of the colour grey to explore the fundamentals of light, space, time, and [kinaesthetic] perception. He appreciated the colour's mystery, softness, simplicity, and capaciousness. His precise, systematic methods, developed over many years, yielded accomplished square paintings and works on paper. Their subtle revelations - absent of illusion, narrative, and symbolic references - expand in the viewer's consciousness. In this comprehensive first monograph, Alistair Rider traces Howell's artistic evolution, from the beginnings of his career in the early 1970s through the artist's greatest achievement - the group of abstractions called Series 10, which occupied the last two decades of his life. Rider's multi-faceted essay also chronicles Howell's biography, including his early studies and accomplishments in architecture, and offers several interpretive frameworks for Howell's oeuvre, notably a connection to East Asian philosophies. The beautifully produced book presents dozens of full-colour plates of artworks and exhibitions, and Rider's essay is thoroughly illustrated with archival images and documents from the James Howell Foundation. This publication makes a critical contribution to the re-evaluation of an artist whose studies of light into shadow have for many years been in a dynamic conversation with recognized trends in contemporary art.
