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.

Wolfenbüttel, Herzog August Bibliothek, 147 Gud. Lat. 4° (4451)

s. XIII1 (probably before 1231 for part I; parts II and III seem older; the MS is dated to the 14th c. by Koehler/Milchsack, Haskins and Kunitzsch, and to the 13th c. by Carmassi).


France (Carmassi).


‘Hunc librum posuit hic reverendus pater frater Andreas de Vogelsanc penitentiarius domini pape, quamdiu sibi placet’ (f. 1bisv, 15th-c. hand); Marquard Gude (d. 1689), who annotated the MS.

Parchment, 196 f., MS made of three parts, each copied by one main hand: I: f. 1bis-2+195-196; II: f. 3-161, painted initial at the beginning of Book V (f. 51ra), reserved initials at the beginning of each other book; III: f. 162-194, decorated initials. F. 1bis-2 and 195-196 are two bifolia which served in all likelihood as cover for the MS. F. 1 was certainly added last.

Ptolemaica (2ra-2vb, 3ra-161vb and 162r-194r). Blank: 194v. F. 1bis-2 and 195-196 contain the fragment of a historical (?) text from the 12th or the early 13th c. (1bisr-1bisv and 195r-196v) and added material, including: notes on calendar conversion for the year 1231 (‘anno domini M°CC°XXX° perfecto’), which must be posterior to the text on f. 2r-2v (1bisv); the owner note and further notes by Gude (1bisv); astronomical notes on arcs and chords (195r-196r), where the year 1337 is mentioned (195v). F. 1 contains a table of contents by Gude (1r) and a fragment of a late medieval text mentioning the archbishop of Cologne (1v).

‘Eam pingendi Gratias antiqui feruntur habuisse consuetudinem, ut unam quidem vultum aversam, due quibus illa manum porrigeret aspectarent. Cuius misterii non ignarus dudum — ad huius operis lectionem dignos admittas, indignos abigas. Suam quippe rebus dignis adimet dignitatem, si quis eas communicaverit indignis.’
