Other notes	It was Schulz, Kat. 95 (1934) who identified the hand of Nicholas of Cusa. It was presumably at Erfurt when Nicolas of Cusa wrote his annotations on 2, 15, 16, 17, 26v. He visited Erfurt in May-June 1451; see J. Koch, Nikolaus von Kues und seine Umwelt, Sitz. Heidelberger Akad. der Wiss., Phil.-hist. Klasse (1944-8) 2 Abh., 123-4.

There are isolated diagrams similar to (b) and (c) in GOxfB Digby 23, s. 12 (?), ff. 52-52v. A diagram similar to (c) accompanies Abbo's astronomical texts (see A. Van de Vyer, Les oeuvres inédites d'Abbon de Fleury, Revue Bénédictine 47 (1935) 140-4) in GOxfB Harl. 2506, Fleury, s. 10-1, f. 31, GOxfB Vit. A. XII, (English), s. 11, f. 10, GOxfCS 17, f. 38v, GLonB Cotton Tib. E. IV. Winchester, s. 12, f. 141v. In GOxfB Bodl. 232, f. 21, the diagram stands alone.
Work 13	Title (ms.)	Diagram

Ian."; "Incensio pascalislune"; three series of letters: "ad lunam", apparently "litterae punctatae"grouped in twos or three beg.: C..M, ending DO.P; "anni", in Greek numerals; "ad terminum", single letters, apparently relating to the B.-.Q table on 15, but here using it to find the terminal of Easter, instead of its actual date. At the four corners outside the rota, and in the centre, are added formulae for finding the five terminals listed above.
	Additional remarks	Added, s. 12. Set together with another diagram in a red frame with yellow wash
	Folio no.	23v (upper diagram)
	Rubric	Spera ad inveniendos terminos per circulum anni atque eorum lunationes
	Additional copies	There is a similar rota, with fewer data, in SMadN 9605 (s. 12) f. 85. In GOxfB Bodl. 232 (s. 11) f. 21v there is a rectangular table which displays most of the data found here. It is called: "Spera terminorum in festivitatibus annorum".
Work 14	Title (ms.)	Text and diagram showing how gravity affects the fall of rain

	Folio no.	23v (lower diagram)
	Additional copies	The same diagram and text follow an extract from Isidore (De Nat. Rerum XI. 1-3) in GOxfCS 17 f. 39v (in these MS. text and diagram are preceded by Abbo's "Sententia", for which see A. Van de Vyer, Les oeuvres inédites d'Abbon de Fleury, Revue Bénédictine 47 (1935) 140-4) and GLonB Cotton Tib. C. 1, Peterborough, s. 12, f. 7. In GOxfB Digby 23, f. 52, the diagram, i a form mauch closer to ours, stands alone.
Work 15	Author standard	Beda
	Title (ms.)	De Nat. Rerum XVI
	Incipit	Zodiacus vel signifer
	Publ. descriptions	For a discussion of the diagram and its relation to the Pliny excerpts see also H.P.Lattin, The 11th cent. MS. Munich 14436, Isis 38 (1947-8) 215-22 & fig. 2. For the Baltimore MS. see H. Bober, Journal of Walters Art Gallery 19-20 (1956-7) 85-6, 90, 92, & fig. 14-5
	Printed copies	Pr. J.-P. Migne, Patrologiae Cursus Completus, Series Latina, 90 col. 231; the diagram, col. 363-4A & 1153-4B is different again; for the note by Cusanus, see 107 col. 690B7-C8; Rabanus is however copying Bede.
	Additional remarks	Added, s. 12, in blank space
	Folio no.	26vb
	Explicit	duabus ut sol.
	Glosses etc.	In the lower margin Cusanus has written: Ad illam figuram vide Rabanum in c(apitul)o de cursu planetarum per signiferum quod et hic ascribitur.
	Math. drawings	The text accompanies a diagram entitled "Cursus planetarum per zodiacum".
	Additional copies	The diagram is similar to one found in GOxfB Canon. Class. Lat. 279, s. 9 (?), f. 34, where it accompanies the first part of the so-called York Excerpts from Pliny's Nat. Hist., ed. K. Rück, Auszüge aus der Naturgeschichte des C. Plinius Secundus (Progr. Königl. Ludwigs-Gymnasium (1887-8) 34-43. In GLonB Cotton Vit. A. XII, f. 9, it is used to explain the "Sententia Abbonis" for which see A. Van de Vyer, Les oeuvres inédites d'Abbon de Fleury, Revue Bénédictine 47 (1935) 140-4. See also GOxfCS 17, f. 38; GLonB Cotton Tib. E. IV. f. 141 and Walters Art Gallery, Baltimore, W. 73, English, s. 12, f. 5v. In this last MS. the Bede text is on f. 2.
