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.

Vatican, Biblioteca Apostolica Vaticana, Pal. lat. 1414

s. XIII2 (f. 224rb: ‘Explicit liber presens anno salutis incarnationis domini Ihesu Christi M°CC°66, 12 die mensis Novembris. Constat pro scriptura 62 fl. Florentinorum’, this note has been added by what seems to be a later hand, but 1266 is a plausible date for the MS).
