_ (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.

Glosa super 60 propositionem Centilogii Ptholomei


‘(London, BL, Harley 13) Incipit glosa Hispalensis super 60 propositionem Centilogii Ptholomei que incipit sic: Albaharim etc. In oppositione [read propositione] ista Ptholomeus tria tangit. Primum est de occasione dierum creticorum, secundum de diebus indicativis crisis — de cronica et acuta ut de magna causa et brevi.’


A commentary on Centiloquium v. 60. The opening word ‘Albaharim’ shows that the source text was Plato of Tivoli’s translation, even though, as Panti pointed out (p. 91), in one MS (Vatican, BAV, Pal. lat. 1116), this word has been replaced by ‘Crises verius significatio sunt hore etc.’, which corresponds to the opening words in the ‘Mundanorum’ version. Further quotations of the Centiloquium within the text are otherwise from Plato’s translation. All MSS offer basically the same text, the main exception being that two of them have a diagram entitled ‘Circulus 16 angulorum’, either within the text (Vatican, BAV, Pal. lat. 1116, f. 126v) or immediately after it (Berlin, SBPK, lat. fol. 192, f. 81r, among a set of three diagrams f. 80v-81v). On this diagram, see Note below.


Unknown. In the earliest MS, London, BL, Harley 13, copied c. 1300, the text is attributed to one ‘Hispalensis’, while in Vatican, BAV, Pal. lat. 1116, it is ascribed to ‘Linco<l>nensis’, i.e. Robert Grosseteste. The text (with the diagram) was known in the second half of the 13th c. to Peter of Limoges and Henri Bate of Mechelen (Steel/Vanden Broecke).


The diagram ‘Circulus 16 angulorum’, together with instructions for its use (inc. ‘Circulus 16 angulorum describit dies creticos…’), is found in at least three other MSS: Berlin, SBPK, lat. fol. 646, copied c. 1268, f. 19v-21v; Munich, BSB, Clm 244, s. XIV, f. 140v and 146r; and Bamberg, SB, Astr. 4, s. XV, f. 140v-141r, where it forms the last chapter of a longer text of astrological medicine made of five parts (f. 137r-141r, inc. ‘Cum humana corpora sicut omnia ista inferiora et maxime vegetativa…’). As noted above, the diagram ‘Circulus 16 angulorum’ was inserted in the Glosa super 60 propositionem Centilogii Ptholomei in Vatican, BAV, Pal. lat. 1116 (f. 126v), but this MS also preserves the instructions immediately before the Glosa (f. 125v). These instructions have been edited by Dell’Anna, II, 202-205 (from the Vatican and Munich MSS).
