_ (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.

s. XIII¹.


the three parts of the MS belonged to Richard of Fournival (and were copied for him acc. Rouse); Gerard of Abbeville (c. 1261); college of Sorbonne (1272).

Parchment, 146 f., MS made of three parts (f. 2-81, 82-132 and 133-146), each copied by a single neat hand, painted initials at the beginning of each section, numerous decorated initials. A section is missing after f. 81.

Astronomy: Albategni, De scientia astrorum, end gone due to missing folia (2r-81v); Ptolemaica (82v-132r); two diagrams and a note on retrogradation ‘Nota: p est centrum terre, o centrum excentrici deferentis — a primo argumento ad hoc quod diximus’ (132r-132v); Ptolemaica (133r-146v). Blank: 82r (except for the ex-libris of the college of Sorbonne).


Richard of Fournival included the three parts of the MS in his Biblionomia (ed. Birkenmajer, 169), no. 54: ‘Liber extractionis elementorum astrologie ex libro Almagesti Ptolomei per Galterum de Insulla usque ad finem sexti libri ex eo’ (= f. 82v-132r); ‘Item tabule stellarum fixarum ex eodem assumpte (= seems to be missing in the MS, unless it is the same as the following item). Item descriptio quadraginta octo ymaginum Ptolomei cum numero et dispositione stellarum in eis’ (= f. 133r-146v); and no. 55: ‘Machometi Albateigny ben Iebyreinem… Acharram liber in numeris stellarum et locis motuum earum experimenti ratione conceptarum’ (= f. 2r-81v).

‘Minor Almagesti [title in the upper margin, perhaps by another hand]. <O>mnium recte phylosophantium non solum verisimilibus et credibilibus argumentis… (83r) Data circuli dyametro latera decagoni — nam visus locus Lune tunc ipse locus Solis. Et inclinationes quidem tenebrarum sic se habent. Explicit hic sextus liber et sexti glosa textus.’

= Almagesti minor (C.1.4). A few marginal notes by the scribe and, possibly, by another hand. One longer gloss by a later hand f. 87r. The introduction (82v) was added at a later stage and by another hand, as confirmed by the fact that the initial on that page was not executed, while initials on the following pages were.


‘Tabula stellarum fixarum secundum quod semper sunt in ymaginibus signorum. Stellatio Urse Minoris. Tabula stellarum fixarum. Illa que est super extremitatem caude: (longitudo) 2s 7° 15’ – (latitudo) 66° 0’ – (magnitudo) 3. Illa que est post istam super caudam: 2s 9° 35’ – 70° 0’ – 4 — thaugebe dicuntur comete.’
