"Single large leaf, manuscript on vellum, 384 x 250 mm, with main text in double columns of 29 lines in a scrawling gothic bookhand, that encased in gloss in smaller version of same almost filling entire borders and ending with ""Explicit glosa"" at foot of second column with large red paragraph mark with trailing penwork and its capital touched in red, other contemporary interstitial marginalia in hairline script, the capitula list for the entire parent volume on the verso in three columns of very small script with entries lined through in red pen (this a common form of medieval heightening, performing the same function as underlining), bright red rubrics and paragraph marks, simple red initials, simple running title in light brown ink at head of recto as well as a contemporary folio no. 'cclxxxii', details of a legal case included as an example in a 19-line near-contemporary addition at foot of capitula list among other short additions there, recovered from the binding of a later book with the inscription in a French sixteenth- or seventeenth-century hand ""du 13e 14e et 15e siècle"" (probably referring to copies of documents once found within the binding), cockling, tears, small holes, scuffs and stains concomitant with reuse, overall fair and presentable condition"
The Liber Sextus was the second great medieval collection of decretals (letters of the popes promulgating decisions on matters of Canon Law). It was proceeded by those commissioned by Pope Gregory IX from Raymond de Penafort in 1234 (the Liber Extra), and was itself commissioned by Pope Boniface VIII in 1298 from Guillaume de Mandagot, bishop of Embrun, Berenger Fredoli, bishop of Beziers and Ricardo Petroni, papal vice-chancellor. Its gloss was supplied by Johannes Andrew, with additions by Johannes Monachus (d. 1313), and Guido de Baysio (d. 1313)
