15th-century manuscript produced in England, probably London. The volume contains the 'Myrrour of the Blessed Lyf of Jesu Christ', a translation by Nicholas Love, Prior of Mount Grace Charterhouse in Yorkshire, of the Pseudo-Bonaventure 'Meditationes vitae Christi'. The work dispenses meditative and doctrinal comment on scripture and is made up of 63 chapters in 7 sections, each representing a day of the week.

The manuscript was produced for Edmund Grey, 4th Baron Grey of Ruthin, and his wife Katherine Percy. Scott dates the production of the manuscript to sometime between 1445 and 1465. He bases the approximate dating on the presence of Lord Grey's arms impaling his wife's Percy arms following their marriage, which apparently took place by 1444/5, and on the fact that Grey is not styled the first Earl of Kent, to which he was raised in May 1465.

The manuscript is written in a bastarda book hand in double columns of 34 lines each. Each section and chapter has incipits and explicits in a mix of Latin and Middle English given in red. A scribal marginal textual apparatus is evident in the margins of most folios. Pricking is evident for both the horizontal and vertical lines. Each folio has been lined on the recto and verso sides with a frame ruling in pink, except for the occasional recto side of an inserted miniature.

Each section begins with an elaborate colour foliated initial of either seven or nine lines on gold grounds. On folio 9r this initial is historiated rather than floriated. Each chapter begins with gold letters of either two or three lines on rose or blue backgrounds, with sprays of green feathering and gold motifs extending into the margins. Throughout the work there are frequent blue and gold letters of one line, with red and blue penwork. The marginal annotations are in Latin and are given in red, with initials of blue and gold with red and blue penwork. Throughout the work there is a running title in the centre of each upper margin. This is in Latin and given in red, with initials in blue or gold with penwork in red and blue.

Although the 'Mirror' was a very popular text not many copies were illustrated. This copy contains seventeen full-page miniatures, as well as fifteen full borders, and is considered to be one of the most beautifully-illuminated surviving examples among the numerous copies of this work.

There are full page illuminated miniatures on the following folios: 5v, 8v, 12v, 27v, 36v, 46v, 49v, 57v, 66v, 69v, 106v (damaged), 118v, 126v, 129v, 140v, 146v, 149v.

Some of the miniatures are on singletons inserted as an extra leaf in a quire of eight; however, the method of insertion was not consistent, as some miniatures are part of the regular quires.

There are full bar-frame conventional borders on folios 6r, 9r, 13r, 28r, 37r, 50r, 58r, 67r, 70r, 107r, 127r, 130r, 141r, 147r, and 150r. Folios 47r 119r lack a border.

For further discussion of the miniature and border work see Scott.

Horizontal catchwords are present on the following folios: 15v, 23v, 76v, 92v, 100v, 108v, 125v, 133v, 141v, 150v, and 158v.

Quire signatures in the form of lower case numbers, Roman numerals, and symbols are present on the following folios: 16r, 17r, 18r, 19r, 42r (cropped), 43r (cropped), 44r (cropped), 45r, 60r, 61r (cropped), 62r, 63r, 69r (cropped), 71r (cropped), 72r (cropped), 93r, 94r, 95r, 96r (cropped), 101r, 102r, 103r, 104r, 134r (cropped), 135r (cropped), 136r, 137r, 143r (cropped), 144r (cropped), 145r (cropped), 152r (cropped), 153r (cropped), and 154r (cropped).

There is evidence throughout the manuscript of contemporary and modern repairs to the vellum. Some leaves have been mounted on guards, and folio 106 is damaged with substantial loss of text and miniature.
