These words appear beneath a 1652 engraving of Jan Amos Komenský, the polymath scholar, educational reformer and bishop of the Moravian Unitas Fratrum (Unity of Brethren), generally known by his Latinized name Comenius. Comenius made ‘all the world his owne’, not only by winning admirers across a wide geographical area but also, in another sense, through his idiosyncratic endeavours during his long-running exile to bring about a ‘universal reformation’ of the entire world by reordering and teaching all knowledge to all people by means of a ‘universal wisdom’ (pansophia). Comenius's physical exile, brought about by war, became a spiritual and intellectual pilgrimage bringing him into numerous intellectual circles across Europe. Among those connected to the circles influenced by Comenius was the poet John Milton. Though not physically exiled, Milton, too, utilized exile motifs in his writing and, like Comenius, was a teacher who proposed educational reforms. Both men saw the world as suffering a cosmic exile caused by the Fall of humanity, and both saw education as having the potential, at least in part, to restore the harmony of the world and thus to reverse this cosmic exile.
