On f. 2 is written ‘The Ladie Isabell Fairfax daughter and hare of Thwats hir bouk,’ on f. 8 ‘This boke belongeth to my lady farfax off Steton,’ and on f. 1 ‘S^r Thomas fayrfax of Denton Knighte true owner of this booke, 1588.’ This Lady Isabell Fairfax was the granddaughter and heiress of John Thwaites of Denton, who died in 1511, and was married to Sir William Fairfax of Steeton. Sir Thomas Fairfax of Denton, whose name appears in the book, was her grandson. The book no doubt came from the Thwaites family, and we are thus able to trace it back as far as John Thwaites of Denton, who died in old age not much more than a hundred years after the death of the author. It was bequeathed with other MSS. to the University of Oxford by Sir Thomas Fairfax the parliamentary general, grandson of the above Sir Thomas Fairfax of Denton, and was placed in the Bodleian Library in 1675. The first leaf of the text, up to Prol. 146, is written in a second hand which has also written ff. 186-194, including the last lines of the _Conf. Amantis_ from viii. 3147. A third hand (with very different orthography) has written viii. 2938-3146, being the last 29 lines of f. 41 v^o (over an erasure) and the whole of f. 185, which is a leaf inserted in the place of one cut away (the last of quire 23). At viii. 2938 there is visible a note, ‘now haue, etc.,’ for the guidance of the scribe after the erasure had been made. From the fact that two hands have been employed in the transformation of the MS. at the beginning and end it seems probable that the changes were made at two separate times (as we also know by the dates that the rewritten epilogue preceded the rewritten preface), and that what I have called the third hand was really the second in order of time, being employed to substitute the later epilogue for the former, while the other hand, doing its work probably after the accession of Henry IV, replaced the first leaf by one containing the Lancaster dedication, which had been in existence since 1392-3, but perhaps only in private circulation, and added also the _Traitié_ and the Latin poems, with the account of the author’s books, ‘Quia vnusquisque,’ in its revised form. I say after the accession of Henry IV, because the reference in the third recension account of the books to Richard’s fall, ‘ab alto corruens in foueam quam fecit finaliter proiectus est,’ seems to require as late a date as this. It should be noted that this hand is the same as that which has made somewhat similar additions to the All Souls and Glasgow MSS. of the _Vox Clamantis_. Other examples of alteration of first recension readings by erasure in F are Prol. 331 _marg._, 336, i. 2713 f., iv. 1321 f., 1361 f., _Lat. Verses after_ vii. 1640, _Lat. Verses after_ vii. 1984.
