This book is the second volume of a projected 3-volume edition which aims to contribute to our understanding of Robert Persons's significance as a controversial figure in early modern European history. It includes documents and letters by Persons, as well as letters to Persons, notably from the superior general of the Society of Jesus, Claudio Acquaviva. Letters in Latin, Italian and Spanish are presented both in the original language and spelling and with English translation, and letters in English in original spelling. The correspondence in this volume covers Persons's eight-year sojourn in Spain following the failure of the Spanish armada of 1588, the repercussions of the death of William Cardinal Allen, and Persons's return to Rome in 1597 to deal with disaffected students at the English College.
