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.

Paris, Bibliothèque nationale de France, lat. 7350

s. XVIin (perhaps c. 1510, cf. date 9 June 1510 written by the scribe in the upper margin of f. 136r).


the MS preserves the astronomical and astrological teaching delivered at the University of Cracow in the late 15th c. (numerous mentions of the years 1483-1488 throughout) and derives at least partly from a MS of Johannes Virdung of Hassfurt (cf. f. 16r: ‘… excripse ex tabulis magistri Iohannis de Asfur…’, f. 125v: ‘… ex libro magistri Iohannis de Hasfurt’, f. 219v: ‘… hec de revolutione nativitatis scripsit magister Iohannes de Asfurt manuscriptum’). The MS is indeed very close in content to Vatican, BAV, Pal. lat. 1439 (see), a MS copied in Cracow by Johannes Virdung mainly in 1487-1488, even though it does not seem to have been copied on it.
