Printed in upright Roman font. Spaces are left for poem and book initials, with small guide letters: alternating blue and red capitals have been executed throughout (incl. Gosbinus). Note especially the illuminated initial for Amphitryo (the previous page has a list of contents, with folio numbers added by annotator); both line-initials and markers of change of speaker have been flashed in red. There are marginalia in a secretary hand on many pages of the Plautus, offering variants and explications; Miles Gloriosus is particularly heavily annotated (note the 'manicule' on f. 131r, e.g.). Many of the MS folio numbers have been trimmed.
Of Gosbinus I know nothing, and neither apparently does the internet! An inserted ms note describes him as 'per Brabantiam et Lymburgiam Cancellarius', and says the work was finished at Brussels in 1460.
