A verse from Caxton's Book of Curtesye, printed at Westminster circa 1477.
Kembe your hede, & loke you kepe yt clene;
your eres twayn suffre not fowle to be;
In your wysage loke no spote be sene;
purge your nose; lett no man in yt se
The vile matter; yt ys none honeste;
Ne with your bare hond no fylth from yt feche,
for that ys fowle, & an vncurtoys teche.
Comb your head and look you keep it clean;
Both your ears suffer not foul to be;
On your face be sure no spot is seen;
Purge your nose; let no man in it see
Vile matter; it is not honorable;
Nor with your bare hand no filth from it fetch,
For that is foul, and a discourteous fault.
