Justinian's 'Novellae Constitutiones' or 'Authenticum' Manuscript volume, containing a copy of the 'Authenticum' of Justinian's 'Novellae Constitutiones'. It was not included in the 19th century editions of Justinian's Novellae but it is very similar to a copy (now missing) from Klosterneuburg described by Gustav Heimbach in 1851, suggesting that both copies shared an examplar. This copy has been heavily corrected throughout and there are many gaps in the original text either due to scribal error or a corrupt exemplar. Although a portion of the end of the manuscript is missing, the text itself is an unusually early codified version of the 'Authenticum'. It includes a copy of a note originally of the sixth century, which gives a description of the original bilingual [Latin and Greek] collected Novellae, and several sets of unique pre-Accursian glosses datable between the late twelfth and mid thirteenth centuries. Collation: 1-9(8), 10(6), 11(8), 12(1). ff.ii+87+ii, 325x200mm, written space 220x120mm. 2 columns of 46-49 lines. In several hands, with some small drawings. 19th Century binding. Ker suggests this manuscript was probably produced in France, as the 13th century marginalia are in a French hand. 12th Century
