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.

‘Incipit liber qui Centiloquium appellatur. Dixit Tholomeus: Iam scripsi tibi, Iesure, libros de hoc quod operantur stelle in hoc seculo… Scientia stellarum ex te et illis est… Quod dixit Ph<tolome>us, ex te et illis, significat qui priores futuras prenoscere desiderant — et quanto melius qui vidimus exposuimus.’

, in ‘Mundanorum 2’ only. A few short marginal notes, mainly by the scribe, but also, on f. 3r, by a later hand. This copy includes horoscopes within the text on f. 8r (4), 9v (2), 14r (2) and 14v (1); a table of terms ‘Termini Tholomei’ on f. 14v; and notes on f. 15r, including ‘prima die Ienuar<ii> MCC21…’. The planetary positions show that all horoscopes were cast for various dates in 1220 (the mention ‘anno domini 1202’ above the third horoscope f. 8r is evidently a mistake by someone new to Arabic numerals or suffering from dyslexia). At least some of these horoscopes are interrogations and elections, apparently by or for some ruler, cf. e.g. ‘Interrogatio domine commune’ (horoscope 4, f. 8r) and ‘Eodem die 7 hora comes electus fuit in Pt (?)’ (horoscope 6, f. 9v), and one of these horoscopes mentions Mantua: ‘Die Mercurii 12 hora, extratus (?) fuit carocius causa eundi in servicio Mantue, V die exeunte (?) Madio’. On these horoscopes, see also Lemay and J.-P. Boudet, ‘Les horoscopes princiers dans l’Occident médiéval (XIIe-XVe siècle)’, in I saperi nelle corti.
