1857.  trans. Uhland, in Charleston Daily Courier, 11 Aug., 4/1.

        Hast thou seen that olden castle
  Which looketh on the sea,
Around whose lofty towerets
  The clouds dance merrilie!

1876.  J. G. Stapelton, Shall He Live Again?’ 61.

        There on upstepping terrace o’er the tree-
Tops rose red gables steep, and clustered roofs
O’er-topped with sheeny towerets and spires
Enlifted high into the cloudless air.
