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.3.7

Reimbotus de Castro
Commentary on the Centiloquium


‘(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.’


A commentary on the Centiloquium starting with v. 2 and skipping other verba. The original text is not included.


Written by Reimbotus de Castro after 1356 and perhaps when he studied in Paris in 1366. The only known MS is Reimbotus’s autograph.
