_ (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.

Summary of the Quadripartitum

Text

‘(ed. Padua 1658) Cl<audii> Ptolemaei Pelusiensis mathematici Opus de siderum iudiciis quadripartitum cum breviariis ad singula capita D. Placidi de Titis. (1-51) [book i] Liber primus. Cap. I. [placidus de titis’s summary] Duo innuit cognoscenda in hac arte, familiaritates astrorum per motum acquisitas et eorum ad agendum naturas… [ptolemy’s text] Duo sunt, Syre, quibus pervenitur ad astronomicas praedictiones, praecipua quidem et maxima. Unum quod primum et loco est potestate, quo Solis, Lunae et stellarum motuum configurationes — Sed extra haec omnia reperti imbecilles et prorsus infirmi habentur. Finis libri primi. (52-94) [book ii] Cl<audii> Ptolemaei Pelusiensis de iudiciis astrorum liber 2. Cap. I. [placidus de titis’s summary] Ad effectuum naturalem praemeditationem descendit, quae duplex, universalis regionum et urbium, et peculiaris singularum hominum proponit hic de priori… [ptolemy’s text] Hactenus quidem percurrimus ea, quorum maxime cognitionem praedictiones rerum singularium requisiturae viderentur — Quod superest, genitales praecognitiones sicut et ordo postulat nunc deinceps exequemur. Finis libri secundi. (95-160) [book iii] Cl<audii> Ptolemaei Pelusiensis de iudiciis astrorum liber 3. Cap. I. [placidus de titis’s summary] Expositis iam universalium effectuum causis, nunc descendit ad causas particularium, quam genethliacam partem vocat… [ptolemy’s text] Explicata a nobis in prioribus communium eventum consideratione, nimirum quae et natura praecedit — agiliora milleque modis varia, et cautius instituta. Finis libri tertii. (161-178) [book iv] Cl<audii> Ptolemaei Pelusiensis de iudiciis astrorum liber 4. [placidus de titis’s summary] Hactenus de iis quae genesis tempore foeto innascuntur, hoc ultimo libro proponit ea qua aliunde et deinceps adventant. [ptolemy’s text] Quae igitur genituram praecedunt illive connexa sunt, amplius ea quoque quae eam comitantur — si mathematici causam erudite cum ea quae extemperatura nascitur, comparemus. Finis libri quarti.’
