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.

Nürnberg, Stadtbibliothek, Cent. V 85

s. XV2 (before c. 1465).




Regiomontanus, who acquired the MS in Rome about 1465, glossed it and added notes on f. 78v; Bernhard Walther; Nürnberg, Ratsbibliothek. The MS was also apparently used by Johannes Schöner, who inserted Regiomontanus’s notes on dignities and debilities exactly as they appear in the present MS (f. 78v) into his Opusculum astrologicum (ed. Nürnberg, Johannes Petreius, 1539, II.38, sig. [H4]v).

Paper, 78 f., a single neat hand, except for glosses and additions by Regiomontanus.

Astrology: Leopold of Austria, De astrorum scientia (1r-45v); Ptolemaica (49r-78r); notes added by Regiomontanus: list of dignities and debilities according to Antonius de Monte Ulmi (78v) and distribution of Italian cities in the twelve zodiacal signs according to Franciscus de Esculo (78v). Blank: 46r-48v.
