Schrift und Hände

littera carolina. Many hands.


  • At least 16 major tituli in square capitals (usually red), usually with uncial E, often with uncial h and/or D;
  • lesser tituli and capitula titles in uncials (normally red);
  • tituli twice in rustic capitals (addition on 69v, and 204r);
  • 9- and 5-line plaitwork initials on 2r and 5r.
  • Through most of codex, initials are 2 to 11 lines, pen-decorated in red and black in simple designs;
  • 1- to 4-line incidental initials, red and/or black;
  • diagrams and rotae in black, red, green.
  • Different decoration on ff. 146r-171v (quires xxi-xxiv, Titel: Scholia in Arati Phaenomena ), with multicolored initials up to 15 lines, in Insular-influenced style (reddish brown, orange-red, green, tan, gray-blue);
  • initials on 146r-153v are more elaborate, including beast and bird heads, (also human head on 146r), with red-dot decoration;
  • astrological illustrations on ff. 154v-167r, the following painted in colors: moon 154v (winged Selene with cresent on head, in chariot drawn by two horses), Arcturus Minor et Maior 155r-v, Serpens 156r, Hercules 156v;
  • other constellations added later in ink outline (poor quality work), some done in part or left blank;
  • in this Aratus section, tituli are also in square capitals with a few uncial letters (as in rest of codex), but smaller than elsewhere, and here also stroked with colors;
  • likewise incidental initals stroked with colors. The illustrations in color may also be a little later than the original phase of the book's production, since the quality of work is not as good as in the decorated initials in this section. On the illustrations, see G. Thiele, op. cit. below, and Bischoff, "Über Einritzungen ", loc. cit. below.


9c corrections (although for the most part, texts remain corrupt), tironian notes; a few modern notes in margin.

Geschichte der Handschrift


"Codex sancti petri scriptus sub pio patre hildebaldo archiepiscopo" ( f. 1r - Hildebald Abp. of Köln 786-819 ).

annales Colonienses in Paschal table f. 76v

list of names, mentioning also Hildebald and Charlemagne, f. 219v; see also Calendarium additions ff. 72v-76r.

This manuscript is a collection of texts from Irish and Anglo-Saxon schools, according to W. Stevens, "Sidereal Time ", loc. cit. This is one of the four manuscripts which Bischoff named as being among those which without any doubt originated at Köln ( "Panorama ", loc. cit.); this ms. is probably also listed in the Köln catalogue of 833. Evidence for origin at Köln includes owner marks ff. 1r and 219v (mention of Hildebald and Charlemagne), Calendarium ff. 72v-76r, and notes added in paschal tables f. 76v. Uniform page layout, similar rubrication, and quire signatures written by text hands indicate that the codex was intended as a unified book, although built up from booklets of various texts, apparently begun in 798 and completed in 805; ff. 2-14 (quires i-ii) may be the earliest part of the codex, where text on 14v calculates the current date as A.D. 798, which is also 1st year of paschal table f. 76v; or this ms. may be copied from an exemplar dating from 798; date 805 given as current year ff. 55r and 76r. Quires xxi-xxiv form a booklet with distinctively more elaborate decoration; elsewhere there are blank pages or half-pages at ends of some quires; changes of hand usually occur between quires. As noted by C.W. Jones, Bedae Pseudepigrapha, p. 115, this ms. is "one of the most important of the early computistical manuscripts in every respect, but the texts are carelessly copied." The many errors remain, for the most part, uncorrected. Not identifiable with Decker, nr. 36 ("Item Bedae de temporibus), which could be Hs. 103, unless Hs. 103 is Decker's nr. 92 ("Compotum Bedae vol. I")(see Frenken , loc. cit.); Hs. 83-II should be identified with Decker's nr. 91.

    (Omss) See McGurk, op. cit. pp. 319-320 , for other illustrated copies; also: Praha, Sk.Uk. 1717 ; Vat. reg. lat. 1324 (= Thorndike-Kibre 124 ). Maass, ed. cit. p. 101 , uses 10 mss. for edition (this ms. = K); cf. this ms. esp. to Dresden 183 . Spaces for illustrations throughout text, not all filled in; some illustrations painted, some only drawn in sketches (on illustrations see G. Thiele, op. cit., Bischoff, "Über Einritzungen", loc. cit., and McGurk, op. cit.). This ms. listed in E. Zinner, Verzeichnis der astronomischen Handschriften des deutschen Kulturgebiet (Munich 1925), nr. 705. Referring to this ms. in relation to the other extant illustrated Carolingian mss. of this text, McGurk (op. cit. p. 319) writes, "The most beautiful of the group, its quality and its early date suggest that it might be close to an exemplar at the palace." This text, known as the Revised Aratus Latinus, probably dates to the 8c, and is based on the anonymous prose translation ( Aratus Latinus, probably 7c) of Aratus' Greek, plus scholia ( 3c) to the translation of Aratus by Germanicus Caesar. See McGurk, op. cit. p. 318, for more on the relationship of this text to the original poem of Aratus and other Latin versions.
