_ (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.

Commentary on the Almagesti minor

Text

‘(Florence, BR, 885) [text] Almagesti [title in upper margin]. Omnium recte phantium (!) verisimilibus coniecturis etc. [followed by about 15 lines left blank]. Data circuli diametro latera decagoni, pentagoni, exagoni… [proof] Sit circulus abg cuius diametri adg centri d — sit medians celum notum et t oriens quod erit notum per 18am huius secundi. a sit…’

Content

A commentary on the first two books of the Almagesti minor (C.1.3) with original proofs. As it stands in the only known MS (Florence, BR, 885), the work is incomplete, ending abruptly in the middle of a sentence at the bottom of f. 123v.

Origin

The commentary is anonymous. The only known MS was copied around 1300, perhaps in northern Italy (Padua?), where the MS was by the second half of the 14th c.
