Over the past twenty years Anthony Petullo has assembled an outstanding collection of works by artists who are often described as “self-taught,” “naive,” or “outsiders.” In Art Without Category, he calls those labels into question, exploring the lives and work of ten extraordinarily gifted artists from Great Britain and Ireland who operated outside the artistic mainstream, determinedly and sometimes obsessively pursuing their singular visions. All received some degree of recognition during their lifetimes, yet they are, as Petullo writes, “orphans without an art family,” creating works that do not fit into the conventional narrative of twentieth-century art. This abundantly illustrated volume, which includes an introductory essay as well as a biography of each artist, demonstrates that they are nevertheless an essential part of the story.
