1. Thorney Abbey Manuscripts Related to MS 17

Cambridge. University Library Additional 3020-3021 (Red Book of Thorney)


1. Pp. 5-6 + fols. 7r-9r (n.b. first leaf paginated, thereafter foliated) comprise a chronological table from 1085-1501, containing in parallel columns a list of the kings of England, the abbots of Thorney, and the bishops of Ely. The table was drawn up ca 1456, possibly by the same scribe that added the signatures to the quires of MS 17. There are additional annalistic notes in a late 15th or early 16th century hand.

2. The remainder of this large volume is the cartulary of Thorney Abbey, in nine parts, comprising royal charters, donations, papal and episcopal charters, and acta of the abbots. The first phase of copying was apparently conducted in the early years of the reign of Edward III. Blank sheets were left at the end of each section for additions. Two waves of systematic addition were carried out by two principal scribes, who inserted charters and documents of the later 14th and 15th centuries. The hand of the second of these scribes is contemporary with and possibly identical to the hand which wrote the annals for 1396,1397 and 1399 in the Paschal tables of MS 17, and the Greek alphabet on fol. 11v.
