A Latin version, by an unidentified translator, of a Greek treatise by Barlaamus, theologian and bishop of Gerace, Calabria, against papal primacy: 'Doctissimi Barlaami Tractatus de Primatu Papæ e Græco exemplari in Latinum conuersus, sic vt vtriusque libri singule pagine mutuo respondeant' (First line, 'Est hoc positum ab artium scientiarumque peritis, humanissime Francisco ...'; last line, '... vt tibi cum qva decet animi moderatione patienter auscultabo') (ff. 1-22 verso).
The translation is independent of that in the bilingual edition of John Lloyd, Του σοφωτατου Βαρλααμ λογοσ περι τησ του παπα αρχησ. Barlaami de Papæ principiatu libellus nunc primum græcé & latiné editus (Oxford, 1592, ESTC S112537).
