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.

Basel, Universitätsbibliothek, F.III.25

s. XIIIex (f. 45-51, the rest of the MS dates from the 13th and 14th c.).


‘Hunc comparavit magister H. de Wess… (?) librum pro duabus marcis in vigilia beati Mathie apostoli’ (f. 44r, partly erased); the MS belonged to Johannes Tagstern, Dominican friar in Basel, then to the Dominican convent in Basel (f. 1r: ‘Conventus Basilien<sis> ordinis predicatorum est iste liber et fuit quondam Iohannis Tagstern professionis eiusdem’; inner front cover: ‘Iste liber est fratrum predicatorum domus Bas<iliensis>’, 15th-c. hand); ‘Ex libris Academiae Bassi<liensis>, 1559’ (f. Ir).

Parchment, I+51 f. Composite MS made of four parts of various origins (f. 1-8, 9-16, 17-44, 45-51). The fourth part, containing the Ptolemaic sections, is copied in a single hand. At least one folio is missing at the beginning and f. 51 has been glued on the back cover, so that the verso of that folio is now inaccessible.

Astronomy, computus and astrology: Petrus de Sancto Audomaro, Tractatus de semissis, c. 1-10 (1ra-7vb and 9ra-16rb); canons of Toledan tables, fragment (8ra-8rb); ‘Incipit quoddam preambulum de theorica planetarum. Cuilibet planetarum assignatur triplex locus…’ (17r-18v, as introduction to the following text); Theorica planetarum Gerardi (18v-26r); Pseudo-Messahallah, De compositione astrolabii (26v-41r); Johannes de Pulchro Rivo, Computus (41v-44r); scattered notes (44v); Ptolemaica (45ra-51rb); ‘Si volueris scire qua hora luceat Luna singulis noctibus…’ (51rb-51v, but f. 51v is illegible). Blank: Iv, 8v, 16v.

‘…nes non intromitamus quia non apparet electionis proficuum licet proficeremus. 7. Non poterit dare iudicia secundum stellarum complexionem nisi homo qui vim anime — maximus namque error foret si traderetur illi. Et ego Deum precor ut te diligat. Et perfecta est huius libri translatio 17 die mensis Martii, duodecimum mensis Gumedi et secundi anno Arabum 530. Explicit Centilogium Ptholomei cum commento Haly.’

= Abuiafar Hamet filius Joseph, 〈Commentum in Centiloquium〉 (tr. Plato of Tivoli) (C.3.1.1)

, starting with the last line of v. 6, due to one missing folio at the beginning. Glosses by the scribe throughout and by two later hands on f. 46r, 48v and 50r.


‘Ptholomeus dixit quod stelle cum caudis sunt 9 — si cum Iove quicquid ipsa significabit in regibus.’

= Pseudo-Ptolemy, De cometis (B.4)

. Substantial marginal notes apparently by another hand. These notes are astrological but do not seem to be related to the present text nor to the Centiloquium.
