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.

‘Ista est illa nativitas quam ponit Haly Abenrodan in fine Quadripartiti [title in margin by the scribe]. Volo dicere exempla ut melius intelligas quicquid locuti sumus — Et ego primitus volui ponere nat<ivitam> meam quia totum in me probavi et non per auditum.’
