“Most of all they [EP & HD] read Balzac’s Swedenborgian romance Séraphita, about bringing the human soul fully alive by teaching it to see through earthly things to the divine goodness and beauty behind and beyond them. There may have been as much of Swedenborg as of Rossetti [La Vita Nuova and “The Blessèd Damozel”] behind ‘Hilda’s Book’. For Hilda, Ezra was at that time the very image of ‘adolescence in its Ariel, or Séraphita stage’.”
