_ (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.

‘(Munich, BSB, Clm 719a) Ex Theone, Ptolemaei commentatore [note in upper margin by a contemporary hand]. De particularium scientiis. De initiis alicuius doctrinae dicturus planius, sicut in prioribus ea quae de mathematticis (!) speculationibus summatim oportebat proponere — ut X partibus habebimus circumferentiam quae a recta dicta subtenditur. Finis. 1 Dec. <15>56.’


Fragment (I.9-10).


Unknown. The date 1556, found in the only known MS, could as well be that of the copy. This MS belonged to Johannes Praetorius.
