_ (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.

Work C.3.15

Conrad Heingarter
Commentary on the Centiloquium

A commentary on the Centiloquium in Plato of Tivoli’s translation (B.1.2), composed by Conrad Heingarter for the Duke of Bourbon Jean II in or slightly before 1477. The unique manuscript was copied under Conrad’s supervision and was meant to be the presentation copy to the duke. As in the case of his commentary on the Quadripartitum (C.2.10), Conrad composed a preface to Jean II and rewrote and expanded on Haly’s (i.e., Abū Jaʿfar Aḥmad ibn Yūsuf’s) commentary to some extent.

Text

‘(Paris, BnF, lat. 7432) ‘Incipit Centilogium Ptholomei. [text] Prologus Haly. Dixit Ptholomeus: Iam scripsi tibi, Iesure, libros de hoc quod operantur stelle in hoc seculo… Propositio prima. Mundanorum mutatio ad hoc et ad illud corporum supercelestium… (135r) [conrad heingarter’s preface] Vetus oppinio est (ut dicit Cicero) iam usque ab heroicis ducta temporibus eaque et veteris populi Romani et omnium gentium firmata… ego vero tuus Conradus Heingarter excellentissime princeps Iohannes Borbonii atque Arvernie dux — illis premissis rem accedamus ipsam. [comm.] Dixit Ptholomeus propositione prima: Iam scripsi tibi, Iesure, id est domine, libros de hoc quod operantur stelle in hoc mundo et sunt multe utilitatis illis qui volunt prescire futura — [text] … si vero fuerint immobiles, erit proditor ex aliqua civitatum eiusdem climatis. [comm.] … ut perfecta atque completa secundarum stellarum notitia atque eorum (!) significatio (?) appareat. Et inveni quemdam parvum tractatum de speciebus cometum seu cometarum qui Ptholomeo ascribitur, eumque adiunximus in fine verbis Ptholomei, eumque glosavimus ut sequitur.’
