While greatness could not be claimed for Daniel's ‘Rosamond,' it is a moderately complex poem, better and more unified than has been thought. The difficulty is that critics have overlooked the meaning of the celebrated casket. The central section of'Rosamond,’ as indicated by the picture on the casket, is a retelling of the myth of Io in terms of English history in order to inculcate the moral that the sin of lustful prostitution, particularly when adulterous, results in self-metamorphosis into a beast. This transformation occurs despite assurances by a procuress that a god or king can make his own morality and absolve any sin. The central allegorical myth is supported by other moralized myths of lust—those of Neptune and Amymone, Danae and Jove, Atalanta and Hippomenes, and Pasiphae and the bull.
