_ (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.

Michael Ruszoczky (?)
Commentary on the Centiloquium

A commentary on Centiloquium v. 57-97 (and on Quadripartitum II.5-8) found in the personal notebook of Michael Ruszoczky (or Michael de Ruszocycze), copied in 1492-1493 (1493 for the present text), when he was student at the University of Cracow. He would later become a lecturer in philosophy and geometry at the same university between 1496 and 1505 (see Liber diligentiarum facultatis artisticae Universitatis Cracoviensis, I: 1487-1563, ed. W. Wisłocki, Kraków, 1886, 32-33, 42, 46, 49, 52, 54-55, 67, 68, 70). V. 96 is followed by an introduction and four chapters on eclipses, which turn out to be a commentary on Quadripartitum II.5-8 (f. 174r-175r: ‘Advertendum ergo (?) quod in prenosticatione eclipsis quomodo (?) iuxta viam Ptolomei principaliter sunt investiganda…’). The commentary does not include Ptolemy’s original texts.

Text

‘(Cracow, BJ, 2703) Verbum Ptolomei LVII est de medelis unde dum voluerit medicus… (174r) Advertendum ergo (?) quod in prenosticatione eclipsis quomodo (?) iuxta viam Ptolomei principaliter sunt investiganda… Capitulum in quibus terris et provinciis continget efectus eclipsium. Iuxta intentionem Ptolomei efectus eclipsium trans… (?) in civitate concordante cum signo in quo est eclipsis — apparebunt.’
