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.

‘Thebit de hiis que indigent expositione [title added by another hand in upper margin]. Equator diei est circulus maior qui describitur super duos polos orbis ― in oppositione Solis aut propinqui oppositioni erunt retrogradi. Explicit.’

70va–⁠79va

Hic incipiunt scripta super Centilogium Tholomei [title added in the margin by a contemporary hand]. Sicut dicit Ptholomeus in proverbiis Almagesti: Non fuit mortuus qui sapientiam vivificavit, nec fuit pauper qui intellectum dominatus est — Ita et ortus istius et ideo non planeta dicenda sunt. Hic satis enim dictum est superius. Deo gratias. Amen. Explicit scripta supra Centilogium Ptholomei edita a magistro Guillermo de Aragona.
