Several corrections can be seen throughout the manuscript, all of them inline, where the mistakes were removed and written over, thus weakening the paper substrate. They are found mostly in the early pages and are not numerous—perhaps a dozen. They, most likely, were done by the scribe. They are visible on the reverse of the page, as the weakened paper allowed the ink to bleed through.
Additionally, there are a few corrected mistakes in the pagination, some corrected by the scribe and others done in a different hand.
One “correction” involves a word in a stanza -titire- intentionally left out by the scribe, with enough space left between the preceding and following words to be filled in by a different hand.
The last and most significant correction is a word crossed out at the beginning of a stanza, with the new word written above, also in a different hand.
The handwriting in “voir” (first image, from a recognized handwriting by Grecourt) and “et vers” (second image) is highly consistent in style, slant, and letter formation. It is very likely that both were written by the same hand.
