For a few moments I thought perhaps this was by Czech great Alfons Mucha. It is of the period, though, and the two men’s lifespans ran in close proximity.

De Leftwich Dodge became known as a muralist when the genre was at a peak of popularity, commissioned for major public buildings as well as hotels and mansions. Murals were seen as a kind of art that could reach directly to the people. Dodge drew on a variety of styles for his murals, settling on a heroic, neoclassical look. Achieving success with commissions for his murals, Dodge designed his family home in Setauket, Long Island, in 1906, the classical Villa Francesca, named after his wife.

In his private work, Dodge’s paintings show the influence of Impressionism and Fauvism. Toward the end of his career, Dodge became interested in Mayan art. His work is held in the permanent collections of the Metropolitan Museum of Art and the National Academy of Design. --WP
