What metaphors are used in A New England Nun by Mary Eleanor Wilkins Freeman?

If the ending of "A New England Nun" is ironic, it is only so in the sense that Louisa, in choosing to keep herself chained to her hut, has thrown off society's fetters. The enthusiasm with which Louisa has transformed "graceful" if "half-needless" activity into vision and with which she now "numbers" her days with an aural pun on poetic meter by which Freeman metaphorically expands Louisa's artwould have been proscribed for her after her marriage. Such vision is more than compensatory for Louisa's celibacy. Louisa's choice of solitude, her new "long reach," leaves her ironically "uncloistered"and imaginatively freer, in her society, than she would otherwise have been.
