In 1829 Robert Southey published a book of his imaginary conversations with the original Utopian: Sir Thomas More; or Colloquies on the Progress and Prospects of Society. The product of almost two decades of social and political engagement, Colloquies is Southey’s most important late prose work, and a key text of late 'Lake School' Romanticism. It is Southey’s own Espriella’s Letters (1807) reimagined as a dialogue of tory and radical selves; Coleridge’s Church and State (1830) cast in historical dramatic form. Over a series of wide-ranging conversations between the Ghost of More and his own Spanish alter-ego, ‘Montesinos’, Southey develops a richly detailed panorama of British history since the 1530s– from the Reformation to Catholic Emancipation. Exploring issues of religious toleration, urban poverty, and constitutional reform, and mixing the genres of dialogue, commonplace book, and picturesque guide, the Colloquies became a source of challenge and inspiration for important Victorian writers including Macaulay, Ruskin, Pugin and Carlyle.
