Ptolemaeus Arabus et Latinus

_ (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.

Quod si ceteris sic se habentibus, solus Sol fuerit in signo masculino, Luna vero in feminino, atque alterum luminarium in angulo fuerit positum, duces solum erunt vitae ac necis habentes potestatem. Si vero preter hec neque hi, qui doryphoriam faciunt, in angulis fuerint inventi aut angulis testimonium prebuerint, magni solum erunt et in his constituti dignitatibus que ex parte coronas afferant aut in procurationibus seu exercituum prefecturis vel sacerdotiis, non tamen erunt duces.
