Surtees, A Catalogue Raisonné, vol. 1, 212 (no. 611).
The title is a wordplay on the Tarpeian Rock; DGR's cartoon depicts the Topseian Rock (or cliff), with Morris being hurled down from heaven with a copy of his epic poem The Earthly Paradise to a hell waiting below. In the heavens are a saintly picture of Jane Morris as a Blessed Damozel and two patriarchal figures looking sternly at Morris's descent.
