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.

statement of donation dated 1577 from the Spanish orientalist Arias Montano (d. 1598) in exchange for a volume of the Four Gospels (1r).

Cod.: paper, I+146 ff. (irregularly foliated with Arabic-European numerals in pencil on every fith or tenth recto, with only eight folios between ‘30’ and ‘40’ and only three folios between ‘120’ and ‘125’; foliated in reverse order on versos; we follow our own refoliation that places the beginning of the text on f. 1v; no catchwords). A clear Andalusī hand (or maybe two) in black; in Books XI–XIII the hand is smaller and slightly flatter, but in all it is very similar to the one in the previous books, although the possibility of two different hands, similarly trained, cannot be ruled out. Almost fully dotted ductus; occasional vowels, and hardly any shaddas or hamzas. Centered book headings in bold black; chapter headings in bold black; initial words of some new sections in red; some abjad notation with overlines in red. Substantial diagrams in black with abjad notation in red; tables in black and red. Dimensions: 272×235 mm; 19 lines per page. Substantial moisture stains; mold stains; slightly worm-eaten; the first seven folios are substantially damaged with areas next to the upper outer corner torn off, although the text is not affected.

Cont.: astronomy. — Index: title page (Iv); Ptolemaica (1v–146r); Blank: 36v–37v, 52v, 120r, 145v, 146v.

The manuscript, in its current state, contains Almagest VII.3–XIII.11, although there are sections and individual folios missing. In the above index, separations within a same book chapter, such as XIII.8, 141r–v, followed by XIII.8, 142r–v, indicate that the folios are not bound in the correct order even within this book chapter. A preliminary tentative rearrangement would be: VII.3, 143r–v; VII.3, 51r–51v; VII.3–5, 8r–15v; VII.5, 16r–20v; VIII.1–4, 21r–35v; VIII.4, 109r–v; VIII.4–6, 89r–93v; IX.1-2, 94r–96v; IX.2–3, 78r–v; IX.3, 138r–139v; IX.4, 146r; IX.6, 110r–v; IX.6–7, 79r–v; IX.10–11, 47r–48v; X.1–3, 38r–41v; X.3–4, 49r–50v; X.4, 80r–v; X.4–7, 70r–77v; X.7, 127r–v; X.7, 126r–v; X.7, 98r–v; X.7–9, 111r–116v; X.9–10, 99r–v; XI.1, 52r–55v; XI.1, 97r–v; XI.1, 100r–v; XI.1, 56r–59v; XI.2–5, 129r–136v; XI.10–11, 36r–37v; XI.12, 42r–v; XII.1, 43r–46v; XII.1–5, 60r–69v; XII.6–9, 81r–88v; XII.9, 128r–v; XII.9–10, 118r–120v; XIII.1–3, 121r–125v; XIII.3–4, 117r–v; XIII.4, 101r–108v; XIII.4, 5r–7v; XIII.4, 3r–4v; XIII.6-7, 1v–2v; XIII.7, 137r–v; XIII.7–8, 140r–v; XIII.8, 142r–v; XIII.8, 141r–v; XIII.8–11, 144r–145r.
