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.

Vatican, Biblioteca Apostolica Vaticana, Pal. lat. 1368

s. XV1 (f. 43vb-45ra, i.e. the Ptolemaic section, was copied in 1426, cf. colophon f. 45ra, and this date probably applies to f. 34-68, all in the same hand; f. 11-33 date from the 15th c. and f. 1-10 from or after 1522, cf. f. 10vb: ‘Finxit, depinxit et descripsit haec planetarum organa et canones Heidelbergae anno salutis millesimo quingentesimo secundo et vigesimo F. Sebastianus Munsterus Inglemius ordine minoritanus’; it should be noted that this note may relate to the date and place of composition rather than of copy, as it does not seem to be in Sebastian Münster’s hand, to judge from his autograph copy of 1515-1518 now MS Munich, BSB, Clm 10691).

Or.:

f. 34-68 were copied by ‘Conradus de Dyffenbach’ (cf. colophon f. 45ra) probably in western Germany, as suggested by the presence of several works, some unique to this MS, by Johannes de Wachenheim (f. 38r-41r, 49v-50r, 51r-56v and 57v-58v), the deacon of the church St Cyriacus in Worms-Neuhausen, who copied, in 1413, Geber’s Liber super Almagesti in what is now MS Erfurt, UFB, Amplon. F. 382 (see).

Prov.:

Heidelberg, Bibliotheca Palatina; Vatican library in 1623.

Paper (except f. 1-10, on parchment), 68 f., composite MS made of three parts: I, f. 1-10; II, f. 11-33; III, f. 34-68. Part III is undoubtedly copied in a single hand (Conradus de Dyffenbach) and not in two hands, as stated by E. Poulle, Les instruments de la théorie des planètes selon Ptolémée: équatoires et horlogerie planétaire du XIIIe au XVIe siècle, Paris, 1980, 93, who sees a new hand starting on f. 46r and dates f. 46-68 to c. 1460-1480 due to the positions of the apogees in the equatorium f. 59-62.

‘Sequitur Centiloquium Ptho<lome>i continens 100 verba. Scientia stellarum ex te et illis est. Astrologus non debet dicere rem specialiter sed universaliter… <D>ixit Ptolo<meus>: Iam scripsi tibi, Iesure, id est domine, libros tractantes de hoc quod operantur stelle in hoc seculo… Quod dixit Ptolo<meus>, ex te et illis, significat quod qui res futuras desiderat prescire — si autem e contrario erit hostis de regno, pro quo gloriose Virgini sit honor, laus et gloria per infinata seculorum secula. Amen. Et sic finitur Centiloquium Ptho<lome>i, scriptum per me Conradum de Dyffenbach anno domini 1426 festo Epiphanie domini etc.’
