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.

Work C.3.8

Reimbotus de Castro (?)
〈Commentum in Centiloquium〉

A commentary on the Centiloquium copied by Reimbotus de Castro in his personal notebook dating from c. 1356-1388. This commentary may be by Reimbotus, but it may also consist of reportationes of lectures he attended as a student in Paris in 1367-1370, as is the case for other texts in his notebook (Lička, 309 n. 30). The text opens with v. 2 and skips several verba. The original propositions are not included, but the source text seems to have been Plato of Tivoli’s translation (C.3.1.1).


‘(Vatican, BAV, Pal. lat. 1380) Nota circa secundum verbum Ptolomei in Centiloquio. Et inquirit utrum orbes celestes moveantur ab anima in ipsis orbibus existens — tunc destruentur consules regis, quia secunda domus significat consules regis.’
