In 1829 Robert Southey published a book of his imaginary conversations with the original Utopian: Sir Thomas More; orColloquies 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.
