A 14th century manuscript in French prose containing the romance of Ywain (Owain ap Thomas ap Rhodri, otherwise Owain Lawgoch, otherwise Yvain de Galles (c. 1300-1378)). There is a rubric heading: 'Ceste liure est le liure de monseignor Y. et parole de maint buen cheualiers' and the text begins 'En ceste partie dit li contes que misser Yuain le fis au roi Vrien cheuauchait par une grant forest qui estoit apellee la perilleuse foreste ...'. The episode of the lion and dragon fighting (cf. Chrestien de Troyes, Le Chevalier au Lion, ll. 3341 sqq.) occurs on p. 1. There is a lacuna after p. 2. The text ends imperfectly. Inserted at the beginning is a letter to Lord Ashburnham from Thomas Boone the bookseller, 29 New Bond Street, 10 April [1852], concerning his purchase, on 'Ld. A.'s' behalf, of the following lots [at the Louis Philippe sale]: 1108 [Ashburnham Appendix 16] for 1605 fr., 1115 (Ashburnham Appendix 152) for 2150 fr., 1303 (Ashburnham Appendix 167, formerly Williams MS 529, now NLW MS 443D) for 1250 fr. and 1306 (formerly Williams MS 530, now NLW MS 444D) for 1960 fr. The manuscript includes coloured drawings illustrating the text, and a few illuminated initials.
