_ (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.3.3

Propositio de crisi


‘(Cambridge, PC., 204) [text] Propositio Tholomei de crisi. Albahaemi sane et certe sunt hore in quibus declarantur mutationes membrorum (!)… [haly’s comm.] Expositio. Ptholomeus docuit nos in hoc verbo causas dierum determinabilium… (70rb) [comm.] Sequitur figura Ptholomei quam Haly commentator suus describit sic quando et qualiter morbi acuti haberi debent suas determinationes sive ad bonum sive ad malum — aut Scorpione aut in Aquario, tunc illa egritudo est deterior egritudinum isti homini et est dignior ut in eo moriatur quoniam est ex radice superiorum.’


A commentary on Centiloquium v. 60, in Plato of Tivoli’s translation, dealing with the outcome of an illness according to the fixed stars of the twelve signs and various other astrological parameters. This commentary, which includes the original text, as well as Haly’s commentary (except the last paragraph), properly opens with the sentence ‘Sequitur figura Ptholomei quam Hali commentator suus describit…’. The Erfurt MS contains the commentary only and is also the only MS to include (f. 88va) the diagram referred to in the opening sentence (blank space for the diagram in Cambridge, PC, 204, f. 70rb, and Oxford, BL, Ashmole 345, f. 75r).


Unknown. The earliest MS (Erfurt, UFB, Amplon. Q. 215) was copied in England in the beginning of the 14th c.
