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.

Basel, Henricus Petrus, 1561

‘Ioannis Regiomontani mathematici praestantissimi de triangulis planis et sphaericis libri quinque, una cum tabulis sinuum in quibus tota ipsorum triangulorum scientia ex primis fundamentis geometricarum αποδειξεων absolutissime extructa continetur. Quam multiplicem usum haec triangulorum doctrina omnibus legitime philosophantibus adferat non solum ad expedite absolvendas, quaecunque in locis terrestribus ac maritimis occurrant, dimensiones, sed etiam ad intelligendos fontes eius disciplinae, quae extructa est a Ptolemaeo et Copernico De revolutionibus orbium caelestium, qui sana rerum intelligentia sunt instructi, in sequenti opere, quod complectitur ordinatam astronomicorum et geomatricorum problematum descriptionem, tanquam in clara luce intueri et experientia infallibili duce deprehendere poterunt. Omnia nunc simul in lucem edita in gratiam matheseos studiosorum per Danielem Santbech Noviomagum. Cum Caes<aris> maiestatis gratia et privilegio. Basileae.’

‘Tractatus Georgii Peurbachii super propositiones Ptolemaei de sinubus et chordis. Sinuum, chordarum et arcuum noticia ad coelestium motuum cognitionem pervalde necessaria existit, ideo de eorum doctrina restat in praesenti perquirendum — Et similiter sciemus quantitates reliquarum chordarum, facilis ergo est secundum praemissorum tenorem chordarum ad suos arcus cognitio.’
