One of the most important artists of the twentieth century, Mark Rothko (1903-1970) created a new and impassioned form of abstract painting over the course of his career. Rothko also wrote a number of essays and critical reviews during his lifetime, adding his thoughtful, intelligent, and opinionated voice to the debates of the contemporary art world. Although the artist never published a book of his varied and complex views, his heirs indicate that he occasionally spoke of the existence of such a manuscript to friends and colleagues. Stored in a New York City warehouse since the artist's death more than thirty years ago, this extraordinary manuscript, titled "The Artist's Reality", is now being published for the first time. Probably written around 1940-41, this revelatory book discusses Rothko's ideas on the modern art world, art history, myth, beauty, the challenges of being an artist in society, the true nature of 'American art', and much more. "The Artist's Reality" also includes an introduction by Christopher Rothko, the artist's son, who describes the discovery of the manuscript and the complicated and fascinating process of bringing the manuscript to publication. The introduction is illustrated with a small selection of relevant examples of the artist's own work as well as with reproductions of pages from the actual manuscript. "The Artist's Reality" will be a classic text for years to come, offering insight into both the work and the artistic philosophies of this great painter.
