It appears as an appendix to Thomas Birch's "Historical View of the Negotiations between the Courts of England, France and Brussels, from 1592 to 1617", 1749. The work "A Relation of the State of Polonia", produced between 1598 and 1603, used to be attributed to Carew, but in 2014 Sobecki definitively identified John Peyton as the author and the coronation of James VI and I in 1603 as the date of completion. Sobecki's identification is based on Peyton's letters about this work and the finding of a second copy of "A Relation of the State of Polonia" written in Peyton's hand and dated and signed by Peyton himself.
