_ (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.

‘Dicit Ptholomeus: Iam scripsi tibi libros de hoc quod operantur stelle in hoc seculo… Verbum primum [title added by the glossator]. Scientia stellarum ex te et illis est… Expositio [title added by the glossator]. Quod dicit Ptholomeus, ex te et illis, significat quod qui res futuras prenoscere desiderat — et ego Deum deprecor ut te diligat. Perfecta est huius libri translatio 17 die mensis Mercur<ii> (!), 12 die mensis Iumedi secundi anno Arabum 530’ (followed by an explicit added by the hand that copied f. 289vb-290vb: ‘Explicit liber Centilogii Ptholomei qui perfectus fuit cum magno labore die Iovis post Brandones parum ante pulsationem Mat… (?) in castello. Valete domine Thoma’).

Glosses by a contemporary hand f. 280v and 281v, the former of which is a copy, in the margin of v. 51, of Pseudo-Ptolemy’s Dixerunt Ptholomeus et Hermes quod locus Lune… (see below). On the same page (280v), a later (?) hand added further notes related to the topic: ‘Ad inveniendum …m (?) conceptionis sive casus spermatis dicit <Al>bubater…’. Two short marginal notes by two yet different hands on f. 281r.
