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.

Paper, 114 f., several hands.

Collection of questions and commentaries on Peter Lombard’s Sentences. The truncated Ptolemaic section (f. 46r) is followed by an excerpt, in another hand, of Gregory of Rimini’s lectures on the Sentences (46ra-46vb). The text opening ‘Ptholomeus Almaiesti primo ignis quidem regionis etheree nequaquam descendit in orizonta…’ (85rb-87rb) is only a collection of excerpts from Berengarius de Landorra’s Lumen anime.
