_ (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.

‘Mundanorum ad hoc et ad illud mutatio ex corporum celestium mutatione procedit, causas que rerum rimaturum primo corpora celestia contemplari, oportet. Ptolomeus: Item premisi libros in quibus tractavi de impressionibus planetarum in hoc mundo… Ptho<lome>us: Sciencia astrorum ex te et illis, nec convenit peritum illorum prophetare… Expositio. Quod dixit Ptolomeus, ex te et illis, significat quod cum qui res futuras prescire vult — (105ra) et quanto melius quivimus exposuimus. Tho<lome>us: Stelle cum caudis sunt 9 —in regibus et divitibus apparebit. Explicit liber anphorismorum.’

= Pseudo-Ptolemy, Centiloquium (version ‘Mundanorum’) (B.1.4)

, mixed with the ‘Iam premisi’ version (B.1.5). The opening sentence is from ‘Mundanorum’; v. 1-21 from ‘Iam premisi’; and v. 22-100 from ‘Mundanorum’ and, more precisely, from ‘Mundanorum 2’. The text includes Pseudo-Ptolemy’s De cometis (B.4) as the last chapter on f. 105ra-105va. Glosses by the scribe or a similar hand.

105va‑105vb

‘Dixit Tho<lome>us et Hermes quod Lune locus in hora qua infunditur — et hoc expertus fuit multotiens.’
