Among one of the more prominently displayed works is his "Cristo de la Sangre" (Christ of the Blood) or "Hermandad del Cristo Crucificado" (Brotherhood of the Crucified Christ), on display at the Museo Reina Sofia in Madrid. He also painted a similarly painting of individuals undergoing a traditional mortification of the flesh and a bleeding crucified Christ called "The Flagellants" (1900). These paintings were praised by Unamuno in his book on "De Arte Pictorico" as being honest representation of Spain: a Spain "religious and tragic, a black Spain". rooted in the particularly Spanish Catholic fascination with mutilating penance.
