Thayer's paintings that I've viewed in person are roughly painted in most areas, but seen at a distance or in reproduction they work well. Moreover, thanks in part to his personal kind of symbolism, they are unique and, to me, they fascinate.
According to the second link above, Thayer added angel wings to a number of his paintings, but not to depict his subjects (often his daughters) as actual angels. Read the link for an explanation, but for shorthand reasons, the word "Angel" is used below for image captions, and is the title found on the Internet. Today's post features his angel-wing paintings.
Angel - 1889
Winged Figure - 1889
An Angel - 1893
For Robert Louis Stevenson memorial - 1903
Winged Figure Seated upon a Rock - 1903
Almost the same as the previous painting.
Angel - 1903
This seems to be either a study or an incomplete painting.
Or maybe an unfinished work.
Winged Figure - 1904
