In 1869 Richards published "Medea", a poetic rhapsody on the picture by Frederick Sandys. In 1871 his only novel "So very Human" was published, with a title suggested by a phrase from Charles Dickens. Besides the five dramas above, Richards produced four others. One of these, his tragedy of "Norma", based on the libretto of Vincenzo Bellini's opera, was performed for the first time on 5 February 1875 at Belfast, with Miss Wallis in the title rôle. His other dramatic works, which were not published, were "The Prisoner of Toulon", "King Pym, or the Great Rebellion", and "Love and Patience".
