It has been said that when gods fall, the earth shakes.

Yesterday night, the news broke that the Alabama-based African-American artist Thornton Dial had died on Monday at his home in McCalla, just southeast of Birmingham, at the age of 87. A master of what label-loving art historians and merchants might refer to as post-Cubist assemblage or postmodern appropriation, not to mention of his own variety of unaffected expressionism and a fluid style of draftsmanship that was both lyrical and semi-abstract, Dial was an artist whose ideas and creations fit into all and none of those establishment-dictated categories at the same time. As with the most innovative, most remarkable self-taught artists of any time or place, both his worldview and the evidence of his artistic achievement were and remain unique and, ultimately, unclassifiable.
