<i>Il Penseroso</i> by Joseph Mozier, done in 1866.  <a rel="nofollow" class="external text" href="https://books.google.com/books?id=kFYoAAAAYAAJ&amp;pg=PA107">Here (<i>Keim's illustrated hand-book, Washington and its environs: a descriptive and historical hand-book to the capital of the United States of America</i> by De Benneville Randolph Keim, p.107)</a> is a description of the statues in the hall in 1874, which mentions it.  It was not part of the official National Statuary Hall collection, but other works were placed in that room until enough statues were submitted from the states.  Several of those statues are now in the rotunda, but this one was apparently moved to the Smithsonian, and per <a rel="nofollow" class="external text" href="http://americanart.si.edu/collections/search/artwork/?id=18064">here, on the Smithsonian site</a> is now at the American Art Museum, third floor, Luce Foundation Center. Per <a rel="nofollow" class="external text" href="https://books.google.com/books?id=L7IAAAAAYAAJ&amp;pg=PA166">Smithsonian Institution Bulletin 70, <i>The National Gallery of Art</i> by Richard Rathburn, p. 166 (1909/1916)</a> it was moved in 1888.
