"The Castle of Perseverance" manuscript in the Macro MS dates to around 1440, but certain textual errors suggest that this version was copied from an earlier manuscript. Dialectic particularities in the playtext show that it was composed in the first quarter of the 15th century, in the East Midlands, probably around Norfolk. The play contains a reference to “crakows”, the pointed ends of shoes that were popular in this time period. There are six other references to crakows in the literature of this period, dating between 1382 and 1425. Scholars therefore set 1425 as the latest possible date of composition. Stylistic differences in dialect, rhyme scheme and stanza pattern between the banns (an advertisement for the coming performance that begins the play) and certain sections of the play text lead to the argument that the play may have had two or even three authors.
