_ (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.4.7

Conrad Heingarter
〈Commentum in De cometis〉

A extensive commentary on Pseudo-Ptolemy’s De cometis (B.4) composed by Conrad Heingarter for the Duke of Bourbon Jean II. The unique manuscript was copied under Conrad’s supervision and was meant to be the presentation copy to the duke. At least the first part of the commentary was completed on 3 January 1477 (cf. f. 148v: ‘finita fuerunt hec commentaria in Bellapartica tertio die Ianuarii anno 1477o currente’). The commentary goes well beyond the comets and also deals with winds, rain, frost, thunder, earthquakes and the distances of the stars.
