Spain's mirror peninsula found among Campomanes' papers
The 'Description of Sinapia, a Peninsula in the Southern Land' is an anonymous late-17th-century Spanish manuscript. It lay unpublished until the scholar Stelio Cro identified it in the 1970s among the papers of the Enlightenment minister Pedro Rodríguez de Campomanes. It describes a southern-hemisphere peninsula that sits antipodal to Iberia with matching shape and size, and its name is an anagram of Hispania. It is a concrete case of a reform program written as a geographic double of the author's own country and kept private rather than printed.
