These paragraphs contain the whole biographical portion of the "Life," contained in his eight folio pages,--the Author's practice being that of introducing some extraneous matter suggested by, but not connected with the subject of the biography. But in the passages quoted the Author's usual carelessness or ignorance is very apparent. His statements of matters of fact, indeed, are never to be relied upon, being seldom confirmed, and often contradicted by better authorities, and instead of a work of National importance, deserving the liberal patronage it received, it is altogether worthless. Thus Mackenzie might have known, that if Hay was "brought up," and "commenced Master of Arts," at a University in Scotland, it could not have been at Aberdeen, which was not founded until the year 1494; and that if Hay was Chamberlain to a King of France, it could not have been Charles the Sixth, whose reign extended from the year 1380 to 1422. The concluding notice of the supposed time of Hay's death, "towards the latter end of the 14th century," is obviously a clerical error for the 15th century. Instead, however, of favouring the reader with an abridged history of the Kings of France, or some other discursive topic, Dr Mackenzie has in this instance deviated from his ordinary practice, and given a careful and detailed analysis of a Manuscript volume in his own possession, containing three works translated from the French by Sir Gilbert Hay; and this may be instanced as one of the few actual contributions to the Literary History of Scotland, contained in his three folio volumes. It may here be quoted, omitting a somewhat confused and inaccurate account of the original author Honorè Bonnor or Bonnet, Prior of Sallon. "The first Book (he says,) contains 10 Chapters, wherein the Author gives the definition of War, according to the Doctors of Civil and Canon Law, and shows that it had its first rise in Heaven betwixt God and his rebellious Angels; then he treats of the bypast persecutions of the Church by way of commentary upon S. John's Vision of the five Angels in the Revelation, and speaking of the fourth Angel, he acknowledges, That there was a woman that was chosen Pope and that she was an English woman: And after Leon, says our translator, "was chosen a woman Pape, not wittand that she was a woman, the quhilk was of England born."
