Document 7: Rowan Oak: Rowan Oak, also known as William Faulkner House, is William Faulkner's former home in Oxford, Mississippi. It is a primitive Greek Revival house built in the 1840s by Robert Sheegog. Faulkner purchased the house when it was in disrepair in the 1930s and did many of the renovations himself. Other renovations were done in the 1950s. The house sits on 4 landscaped and twenty nine acres of largely wooded property known as Bailey's Woods. One of its more famous features is the outline of Faulkner's Pulitzer Prize–winning novel "A Fable", penciled in graphite and red on the plaster wall of his study. Though the "rowan oak" is a mythical tree, the grounds and surrounding woods of Rowan Oak contain hundreds of species of native Mississippi plants, most of which date back to antebellum times. The alley of cedars that lines the driveway was common in the 19th century. The studs of the house are 4"x4" square cypress, which were hand-hewn. Faulkner drew much inspiration for his treatment of multi-layered Time from Rowan Oak, where past and future seemed to inhabit the present.
