(14th century)
“ For oure book seith, al that is writen is writen for our doctrine, and that is myn entente. Wherfore I biseke yow mekely, for the mercy of God, that ye preye for me that Crist have mercy on me and foryeve me my giltes; and namely of my translacions and enditynges of worldly vanitees, the whiche I revoke in my retracciouns: as is the book of Troilus; the book also of Fame; the book of the XXV. Ladies ”
