Ptolemaeus Arabus et Latinus

_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

s. XIV or XV (for f. 1-82, the rest of the MS dates from either the 14th or the 15th c.).


France (?).


‘Iste liber pertinet Iohanno Colpard de Tornaco [Tournai]’ (f. 141v, 15th-c. hand, perhaps the same that copied f. 122-140 – this owner’s note apply perhaps to f. 122-140 only); Colbert; library of the kings of France in 1732.

Parchment and paper, 143 f., composite MS made of four parts, each copied by a single hand (f. 1-82, 83-98, 99-121, 122-140). Folia 61-81 are in disorder and should be read 79, 63-77, 80, 78, 61-62, 81, as partly worked out by a modern hand that has re-numbered the displaced folia with remarks in French.

Geometry, astronomy, medicine and astrology: notes on Euclid’s Elementa (1r-9r); geometry ‘Questio prima et secunda. Prima dcg satis per se patet…’ (9v-37v); ‘Hec probationes sunt necessarie in theoremate undecimo partis secunde libri Theodosii de speris…’ (38r-60v); Thebit Bencora, Liber carastonis (79r-79v and 63r-65v, beginning missing); Thebit Bencora, De figura sectore, tr. Gerard of Cremona (66r-72v); Ptolemaica (73r-77v, 80r-80v, 78r-78v, 61r-62v and 81r-81v); ‘Geometrie due sunt partes principales…’ (83r-89r); Archimedes, Tractatus de incidentibus in humidum corporibus (89v-94r); Campanus of Novara, De proportione et proportionalitate (94v-98r); Alfraganus, De scientia astrorum, tr. John of Seville (99r-119v); Johannes Damascenus, Aphorismi (122r-125v); Curatus de Ziessele, Compendium theologiae naturalis ex astrologica veritate sumptum (126r-140v); various added notes by at least two hands, including a table of contents (141v). Blank: 82, 98v, 120-121, 141r, 142r-143v.


‘Hec probationes sunt necessarie…’ (38r-60v) consists of a set of notes discussing various texts, including Theodosius’s Spherica, Geber’s Liber super Almagesti, Menelaus’s Spherica and Liber Ameti de proportione et proportionalitate. The section on Geber (f. 41r-44r: ‘Nota in figura tertiadecima primi libri Geber quod arcus ag — sunt equidistantes. Hec probatio est necessaria in figura sectoris’) corresponds, at least in its first part, to the appendix to Geber’s Liber super Almagesti found in some MSS (see C.1.2, under Note). This section is not considered part of the Ptolemaica, because it clearly belongs here to a larger text. On this set of notes, see R. Lorch, ‘Jābir ibn Aflaḥ and the Establishment of Trigonometry in the West’, in R. Lorch, Arabic Mathematical Sciences. Instruments, Texts, Transmission, Farnham-Burlington, 1995, VIII, 13-14.
