Note: Probably all errors for compounds in 'rofe-' (sense 6.(a)); the emendation from 'rose Tyles' to 'rofe Tyles' ('roof tiles') is an easy one, especially since 'rofe nayle' appears nearby in the same account, --but note that some further emendation or interpolation would likely be necessary, since 1 d. per tile (in the 1472 example) is 20 times the going rate for ordinary roof tiles (see Salzman); the companion item of 200 tiles for 16 d. is closer to the mark. Either the 'rose tiles' are something very special and really are 'rose tiles' (tiles bearing the image of, or shaped like, a rose?), or, more likely, 'iiij' should be taken to mean either "iiij C" (which would make the tiles very cheap), or "one quarter" (?i.e. of the previous '200'), which would give 'rofe' tiles the same unit cost as the undistinguished 'tiles'--or an error for "xxxx", which would put them in a similarly appropriate price range. Note that subsequent examples of 'rose tile' measure them in 'quarters,' which supports that intepretation of the 1472 quotation. If the 'rose tile' really all are errors for 'rofe tile' (etc.), then the 'rose nail(es)' are certainly 'rofe nail(es)'.
