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.

‘Omnium recte philosophancium verisimilibus coniecturis credibilibus super medium cursum Lune et quo provenerit numeracio ibi erit verus locus Lune’ (with addition 37v-38r, see below).

= Almagesti minor (C.1.3). The text breaks off in V.9 and is immediately followed by an ‘additio’ consisting of six original chapters (37v-38v): ‘Additio. Ad componendum tabulam equocionis (!) centri Lune sic fac. Primo scias centrum duplex Lune medium… (38r) Ad componendum minuta proporcionalia. Tabula vero minutorum proporcionalium componitur isto modo… Ad componendum equaciones argumenti. Tabulam equacionum argumenti vero compones isto modo… (38v) Ad componendum tabulam diversitatis diametri. Tabula diversitatis diametri componitur sic… Ad componendum tabulam latitudinis Lune. Tabula latitudi<ni>s Lune componitur… De tribus superioribus planetis. Tabula trium superiorum veri motus componitur et cum instrumentis materialibus invenitur. Expliciunt addiciones mee. Sequitur artifi… (?) et est de textu’. Two further additions have been inserted into the text, at the end of Book III (23v-24r: ‘Explicit liber tercius. Sequuntur quedam addiciones quas ego magister Anthonius hic inseravi. Aditio. Tabula equacionis dierum cum noctibus suis sic componitur. Quare arcum si fuerit posita e converso fiat e converso etc.’) and after IV.3 (25v: ‘Addicio. Ad inveniendum medium motum Lune in una die, numerum dierum equalium lunacionis in quibus coniunctiones ad statum similem reducuntur’). Glosses by the scribe, who is almost certainly the person responsible for the additions, i.e. ‘magister Anthonius’.
