D MS Douce 322. S Stonyhurst College MS 23. T Trinity College, Cambridge MS R.3.21. R MS Royal 18 A.x. H MS Harley 1706.
B preserves the earliest and best text of the poem.
S and R are related, with S the better version. B agrees with RS more often than with DTH, but points of agreement with DTH are especially interesting. For this edition emendation of B has been conservatively undertaken by collation with D, S, T, R, and H, considered in that order. Variants that are merely orthographical are not recorded. Variants unique to one MS are also not recorded, unless they provide evidence for an editorial judgment.
