F. Mozley maintained that Foxe preserved a high standard of honesty, arguing that Foxe's method of using his sources "proclaims the honest man, the sincere seeker after truth." The 2009 Encyclopædia Britannica notes that Foxe's work is "factually detailed and preserves much firsthand material on the English Reformation unobtainable elsewhere." It was typical, however, in the late nineteenth and early decades of the twentieth centuries to treat Foxe's text as "not to be trusted....If not the father of lies, Foxe was thought to be the master of inventions, and so readers of the Britannica were advised and warned." Documented grounds Foxe based his accounts of martyrs before the early modern period on previous writers, including Eusebius, Bede, Matthew Paris, and many others. He compiled an English martyrology from the period of the Lollards through to the persecution of Protestants by Mary I. Here Foxe had primary sources to draw on: episcopal registers, reports of trials, and the testimony of eyewitnesses. In the work of collection Foxe had Henry Bull as collaborator. The account of the Marian years is based on Robert Crowley's 1559 extension of a 1549 chronicle history by Thomas Cooper, itself an extension of a work begun by Thomas Lanuet. Cooper (who became a Church of England Bishop) strongly objected to Crowley's version of his history and soon issued two new "correct" editions. John Bale set Foxe onto martyrological writings and contributed to a substantial part of Foxe's ideas as well as printed material. Objectivity and advocacy Foxe's book is in no sense an impartial account of the period. He did not hold to later centuries' notions of neutrality or objectivity, but made unambiguous side glosses on his text, such as "Mark the apish pageants of these popelings" and "This answer smelleth of forging and crafty packing." David Loades has suggested that Foxe's history of the political situation, at least, is 'remarkably objective'. He makes no attempt to make martyrs out of Wyatt and his followers, or anyone else who was executed for treason, except George Eagles, whom he describes as "falsely accused." Sidney Lee, in the Dictionary of National Biography, called Foxe "a passionate advocate, ready to accept any primâ facie evidence". Lee also listed some specific errors and suggested that John Foxe plagiarized. Thomas S. Freeman observes that, like a hypothetical barrister, Foxe had to deal with the evidence of what actually happened, evidence that he
