The Swimming Hole [SEP] Introduction
The Swimming Hole (also known as Swimming and The Old Swimming Hole) is an 1884–85 painting by the American artist Thomas Eakins (1844–1916), Goodrich catalog #190, in the collection of the Amon Carter Museum of American Art in Fort Worth, Texas. Executed in oil on canvas, it depicts six men swimming naked in a lake, and is considered a masterpiece of American painting. According to art historian Doreen Bolger it is "perhaps Eakins' most accomplished rendition of the nude figure", and has been called "the most finely designed of all his outdoor pictures". Since the Renaissance, the human body has been considered both the basis of artists' training and the most challenging subject to depict in art, and the nude was the centerpiece of Eakins' teaching program at the Pennsylvania Academy of the Fine Arts.
