Project icon: lavishly furnished initial letter with a painting of Ptolemy using an astrolab.

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.

Italian hand

Paper, 234 pp. (late medieval or early modern pagination), a single hand. One folio (which contained the end of the Ptolemaic section) is missing after p. 24 (=pp. 25-26). In that place we find instead a group of four unnumbered folia (=26bis-26nonies) bound in disorder and missing text both at the beginning and at the end. These four folia were evidently not there when the codex was paginated.

Astrology and astronomy: Ptolemaica (1a-24b); Giles of Lessines, Summa de temporibus, fragment of Book III, missing beginning and end (26bisa-26noniesb, starting with p. 26octies-nonies, then p. 26bis-septies); Alcabitius, Introductorius (27a-54a); John of Saxony, comm. on Alcabitius’s Introductorius (55a-119b); Thaddeus of Parma, Expositio super theorica planetarum (121a-178a); astronomical notes ‘Nota quod secundum tabulas Tholletanas et Romanas dies naturalis incipit a meridie…’ (178a-178b); Messahallah, Epistola de rebus eclipsium (179a-181b); Geminus of Rhodes, Elementa astronomie (181b-208b); Capitula Almansoris (215a-220a); Hermes, Centiloquium (220a-223b). Blank: 120, 209-214, 224-234.

‘Dixit Ptho<lome>us: Iam scripsi tibi, Yesure, libros de hoc quod operantur stelle in hoc seculo… Sciencia stellarum ex te et illis est… Quod dixit Ptho<lome>us ‘ex te et illis est’ significat quod — in qua inceptum est regnum filiorum Ales. Obiit ergo Abnabez in anno…’

= Pseudo-Ptolemy, Centiloquium (tr. Plato of Tivoli) (B.1.2), missing the last lines of v. 100 due to the loss of one folio. Substantial glosses by the scribe pp. 1-6. No glosses thereafter, except for occasional short marginal notes by a later hand.
