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.

Parchment, 48 f., a single neat hand copied f. 1-46. F. 47-48 contain added notes by two or three hands, the first of which (f. 47r) might be that of the main scribe, albeit in a more cursive fashion. Initials and titles reserved.

Astrology: Albumasar, Flores (1ra-5ra); Gergis, De significatione septem planetarum in domibus (5ra-6ra); Jafar, De pluviis et ventis (6rb-7ra); astrometeorology, at least partly from the Liber novem iudicum ‘Aomar: Ex conventu itaque vel oppositione vel ex Solis…’ (7ra-8vb); Albumasar, Introductorium maius, tr. John of Seville, VI.1 (9ra-11rb); Ptolemaica (11va-43va, 43va-43vb and 43vb-46vb). According to a table of contents added by another hand on f. 1r, the MS also contained Alcabitius’s Introductorius after the Ptolemaic section. The added notes (f. 47-48) contain three horoscopes borrowed from Henri Bate of Mechelen’s Nativitas (47r), hence posterior to 1280; a list of the 28 lunar mansions (47v); Liber Alchandrei, 19-20 (47v); the horoscope of a nativity of 16 March 1265 (47v); two horoscopes of a nativity of 23 December 1267 (48r); an unfinished rota containing the 12 signs and the 28 lunar mansions (48v).
