What is "sartoris"

Sartoris is a novel, first published in 1929, by the American author William Faulkner. It portrays the decay of the Mississippi aristocracy following the social upheaval of the American Civil War. The 1929 edition is an abridged version of Faulkner's original work. The full text was published in 1973 as Flags in the Dust. Faulkner's great-grandfather William Clark Falkner, himself a colonel in the American Civil War, served as the model for Colonel John Sartoris. Faulkner also fashioned other characters in the book on local people from his hometown Oxford. His friend Ben Wasson was the model for Horace Benbow, while Faulkner's brother Murry served as the antetype for young Bayard Sartoris.
