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.

Chicago, The Newberry Library, Case 93-2

s. XV2 (f. 2r-97v were most probably copied between 1453 and 1456, since, in a note f. 93r, George of Trebizond, referring to his age, wrote 60 over 58, cf. Saenger, who used ultraviolet lamp).


Italy (Naples and Rome), George of Trebizond corrected and annotated f. 2r-97v, added the end of the commentary to the Centiloquium f. 90v-93r and copied f. 98r-106r. Theodore Buchinck wrote the headings f. 2r and 13r (Monfasani).

Paper, 106 f., only sporadically numbered, two hands (f. 2r-97v and 98r-106r).

Astrology: Ptolemaica (2r-93r); George of Trebizond, Liber de antisciis et cur astrologorum iudicia plerumque fallant (90v-106r). Blank: 1, 106v.
