This magnificent Hudson River School painting, Hook Mountain, Near Nyack, on the Hudson by Sanford Robinson Gifford, shows the view looking west from the southern shores of Croton Point. Hidden in the trees in the foreground is the rooftop and cupola of Richard T. Underhill’s Italianate villa, which he built in 1846 and christened “Interwasser”.
The image is courtesy of the Yale University Art Gallery, which has made “thousands of images of works in the Gallery’s collection . . . available for free download . . .”
For a similar view from higher up, showing the Underhill vineyards, see this previous post of a wood engraving from Harper’s Weekly.
You should also check out the Hudson River School Art Trail, which includes this painting in an effort to encourage people to “hike in the footsteps of Hudson River School artists . . .” to “see the locations that influenced famous American landscape paintings of the 19th century.”
