_ (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.

Andreas Grzymala
Commentary on the Centiloquium

A commentary on the Centiloquium by Andreas Grzymala of Poznań, professor at the University of Cracow from c. 1447 (when he earned his master’s degree) until his death in 1466. Andreas Grzymala taught astronomy for a few years only, until he became professor of poetry and rhetoric c. 1450. He produced his Canones tabularum resolutarum in or soon after 1448 and it is likely that his commentary on the Centiloquium dates from about that time. He signed his work in the initials of the first words of the preface (‘Gloriosus reor zonas intueri mundiales a limitibus altis’), as was common among Cracow authors of the fifteenth century. The exact nature of this commentary, however, is unclear. Rosińska speaks of university lectures, which is entirely plausible. In the only known manuscript, this commentary consists of a preface (p. 71), a substantial introduction (pp. 72-74) and the commentary proper, which mainly gives the opinion of other scholars (Robert Grosseteste, Albertus Magnus, Ptolemy in the Quadripartitum, Alkindi, Leopold of Austria, Albumasar, Bede, Hippocrates, Almansor, Razes etc.), copied in the margins of the text of the Centiloquium (from pp. 75 onwards). This commentary, however, breaks off after v. 20 (p. 85) and it is difficult to say whether it was left unfinished or whether the scribe of the manuscript stopped copying it at that point. The source text for the Centiloquium is Plato of Tivoli’s translation (C.3.1.1), but the ‘Mundanorum’ version (C.3.1.3) has also been copied in the margin, where it is intertwined with the commentary.
