In his subject matter and intention, late 19th century French painter Gaston La Touche was more influenced by the Rococo style of the 18th century than by his Impressionist contemporaries, but here he shows the bright colors and free brushwork he adopted in his later career.
I also have to wonder — in his portrayal of the lanterns and the figures lit by them — if hadn’t seen Sargent’s beautiful and influential Carnation, Lily, Lily, Rose.
