Parsons Weems' Fable, oil on canvas by Grant Wood, 1939; in the Amon Carter Museum of American Art. Catalog entry: The historian Mason Locke Weems, commonly known by his clerical title, Parson Weems, pulls back a curtain to point at 6-year-old George Washington. Bearing an adult head and holding an axe, George gazes blankly up at his father, Augustine, who questions his son while holding a partially cut cherry tree. All of this takes place in front of a 20th-century brick building, which Wood modeled after his own home in Iowa. The scene illustrates the fable of Washington and the cherry tree, which Weems invented in 1806 for the first president's biography. Wood playfully suggests the artifice of the tale here, presenting the story in the manner of a costumed stage play rather than a real event. Amid the action, two Black figures pick cherries in the background, a reference to Washington' slaveholding past and a reminder of of what often gets left out in historical mythmaking.
