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.

Venice, Biblioteca Nazionale Marciana, lat. VIII.10 (3266)

s. XIII1 (f. 1-188r, probably between c. 1217 and c. 1235 acc. Georges) and XIIImed (f. IIv and 188v-189r), with 14th-c. additions on f. Iv-IIr and 190r-190v.


probably Oxford for f. 1-188; the glossator of f. 1-188, who also copied f. IIv (the first Ptolemaic section) and 188v-189r, seems to be of English background acc. Georges, who notes that he also glossed Geber’s Liber super Almagesti in MS Philadelphia, UP-KC, Ms. Codex 826 (olim Lat. 3).


the MS was glossed c. 1311 by a southern hand that signs ‘Iohannes Amelii’ (see below), perhaps the Johannes Amelii (or Joan Amell) attested as physician to King James II of Aragon from 1306 onwards or the Johannes de Amelio (or Jean d’Amiel) who held various ecclesiastical positions in southern France and Italy from 1317 onwards and was bishop of Spoleto from 1349 to his death c. 1370. The MS was apparently in Padua c. 1399 (Georges) and definitely in Venice in the beginning of the 16th c., for it was one of the models used by Petrus Liechtenstein for his edition of the Almagest in 1515.

Parchment, II+190 f. The original core of the MS was copied by two hands (f. 1r-108r and 108r-188r) and includes decorated initials. The rest was added by the English (?) glossator of the Almagest (f. IIv and 188v-189r), by Johannes Amelii (f. Iv-IIr) and by another 14th-c. hand (f. 190r-190v).

Astronomy: added notes of geometry (Iv-IIr); Ptolemaica (IIv and 1r-188r); added astronomical notes (188v-189r); added notes on the lunar mansions (190r); added astronomical diagrams (190v). Blank: Ir, 189v.

‘Valde bene qui proprie philosophati sunt, o Sire, videntur mihi sequestrasse theoricum philosophie a practico — hec pro facultate pertractantes.’


‘Liber iste precepto Maimonis regis Arabum, qui regnavit in Baldach… Bonum quod fecerunt in eo quod video illi qui perscrutati sunt… (1v) Bonum, domine, fuit quod sapientibus non deviantibus visum est — (132r) et abbreviationum, tunc iam sequitur et honestum est ut ponamus hic finem libri. <Q>uidam princeps nomine Albuguafe in libro suo quem scientiarum electionem et verborum nominavit — (132v) considerantibus picturas, que cum a longe videntur placent, propinque vero non dulcescunt’ (followed by tables, 133r-188r).
