tour, Hobbes made the acquaintance of Fulgenzio Micanzio, a close associate of Paolo Sarpi, who had written against the pretensions of the papacy to temporal power in response to the Interdict of Pope Paul V against Venice, which refused to recognise papal prerogatives. James I had invited both men to England in 1612. Micanzio and Sarpi had argued that God willed human nature, and that human nature indicated the autonomy of the state in temporal affairs. When he returned to England in 1615, William Cavendish maintained correspondence with Micanzio and Sarpi, and Hobbes translated the latter's letters from Italian, which were circulated among the Duke's circle.
