_ (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 Quadripartitum IV


‘(Florence, BNC, Panciatichiano 309) Epitome comentariorum auctoris incerti nominis in Ptolemei de astrorum iudiciis libri 4. Duo sunt principia praecipua astronomicae scientiae. Primum est cognitio stellarum tam erraticarum quam fixarum — Haec autem dicta sufficiant circa explanationem quatuor librorum Ptolemei.’


A commentary on the complete text of the Quadripartitum.


Unknown. The only extant MS was copied in the 17th c. probably in Italy, but the text is likely to date from the second half of the 16th c., for it includes nativity horoscopes for 3 August 1552 at latitude 54° (f. 64r), 4 November 1535 at 45° (f. 67r), 2 January 1546 at 52° (f. 74r), 29 August 1529 at ‘Betuntii’ (f. 86v) and 10 August 1510 at Louvain (87v). That the scribe of the MS is not the author is also clear in the title ‘Epitome comentariorum auctoris incerti nominis…’.
