The Reverend Howard Finster was twenty feet tall, suspended in darkness. Or so he appeared in the documentary film that introduced a teenaged Greg Bottoms to the renowned outsider artist whose death would help inspire him, fourteen years later, to travel the country. Beginning in Georgia with a trip to Finster’s famous Paradise Gardens, his journey—of which The Colorful Apocalypse is a masterly chronicle—is an unparalleled look into the lives and visionary works of some of Finster’s contemporaries: the self-taught evangelical artists whose beliefs and oeuvres occupy the gray area between madness and Christian ecstasy.

With his prodigious gift for conversation and quietly observant storytelling, Bottoms draws us into the worlds of such figures as William Thomas Thompson, a handicapped ex-millionaire who painted a 300-foot version of the book of Revelation; Norbert Kox, an ex-member of the Outlaws biker gang who now lives as a recluse in rural Wisconsin and paints apocalyptic visual parables; and Myrtice West, who began painting to express the revelatory visions she had after her daughter was brutally murdered. These artists’ works are as wildly varied as their life stories, but without sensationalizing or patronizing them, Bottoms—one of today’s finest young writers—gets at the heart of what they have in common: the struggle to make sense, through art, of their difficult personal histories.

In doing so, he weaves a true narrative as powerful as the art of its subjects, a work that is at once an enthralling travelogue, a series of revealing biographical portraits, and a profound meditation on the chaos of despair and the ways in which creativity can help order our lives.

The term outsider art has been used to describe work produced exterior to the mainstream of modern art by certain self-taught visionaries, spiritualists, eccentrics, recluses, psychiatric patients, criminals, and others beyond the perceived margins of society. Yet the idea of such a raw, untaught creativity remains a contentious and much-debated issue in the art world. Is this creative instinct a natural, innate phenomenon, requiring only the right circumstances—such as isolation or alienation—in order for it to be cultivated? Or is it an idealistic notion projected onto the art and artists by critics and buyers?

David Maclagan argues that behind the critical and commercial hype lies a cluster of assumptions about creative drives, the expression of inner worlds, originality, and artistic eccentricity. Although outsider art is often presented as a recent discovery, these ideas, Maclagan reveals, belong to a tradition that goes back to the Renaissance, when the modern image of the artist began to take shape. In Outsider Art, Maclagan challenges many of the current opinions about this increasingly popular field of art and explores what happens to outsider artists and their work when they are brought within the very world from which they have excluded themselves.
