Winslow Homer was American painter, illustrator and etcher, one of the two most admired American late 19th-century artists and is considered to be the greatest pictorial poet of outdoor life in the United States and its greatest watercolorist. Nominally a landscape painter, in a sense carrying on Hudson River school attitudes, Homer was an artist of power and individuality whose images are metaphors for the relationship of Man and Nature. A careful observer of visual reality, he was at the same time alive to the purely physical properties of pigment and colour, of line and form, and of the patterns they create.
