 It was reprinted in 1643, with "Civitas Solis" by Tommaso Campanella, and "New Atlantis" by Francis Bacon.It was not clearly ascribed to Hall by name until 1674, when Thomas Hyde, the librarian of the Bodleian, identified "Mercurius Britannicus" with Joseph Hall, as is now accepted.Hall's authorship had been an open secret, however, and in 1642 John Milton used it to attack him during the Smectymnuus controversy, employing the argument that the work lacked the constructive approach taken in More's "Utopia" and Bacon's "New Atlantis".
