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.

Florence, Biblioteca Nazionale Centrale, Conv. Soppr. J.III.28 (San Marco 180)

s. XIV1 (f. 1-74; late 14th c. for f. 75-82, see Murano, ‘Una miscellanea’, 314).




Coluccio Salutati (1331-1406); convent San Marco in Florence by 1471 (cf. f. Iv).

Parchment, I+82 f., a neat hand copied f. 1-74 and several later hands copied f. 75-82.

Astrology: table of contents drawn up in 1471 by Leonardo Ser Uberti, librarian of San Marco (Iv); Ptolemaica (1ra-19ra and 19ra); Liber novem iudicum (20ra-66ra); three medical recipes, added (66rb); Aomar, De nativitatibus, beginning missing (67ra-73rb); ‘Iudicandi summa hic breviter continet. Primum enim aspiciendum…’ (73rb); Messahallah, Epistola de rebus eclipsium (73rb-74rb); ‘Cum Luna fuerit Capite vel Cauda in uno signo…’ with table: elections from the aspects of the Moon with the other planets (74rb-74v); table: De electionibus secundum cursum Lune per XII signa, 44 topics (74v); Abraham Avenezra, De mundo vel seculo, tr. Henry Bate of Mechelen, excerpts (75ra-75va); short astrological chapters attr. Habraam, Plinius, Doratius, Alfadal filius Ablezehel, Noffil and Mesahala: ‘Capitulum in pretio rerum secundum Habraam. Dicit: Quando scire volueris carestiam aut mercatum…’ (75va-77ra); Bethen, Centiloquium (77rb-78rb); table: elections from the aspects of the Moon with the other planets (78rb); ‘Incipit liber … (?). Nota quod inquit Aristotiles quod cum volueris sumere farmaziam… (78va); ‘Nota de faciebus signorum secundum Haly…’ (78va-78vb); ‘Dicto de significationibus Capitis et Caude per unius…’ (79ra-81vb); ‘Aphorismi Haly cum verbis Alchindri in questione pro capto et captivo…’ (82ra-82vb). Blank: Ir, 19v, 66v. The table of contents f. Iv shows that the MS originally contained 108 f., including the following texts (see also Murano, ‘Una miscellanea’, 312-313): Haly Embrani, De electionibus horarum (formerly f. 69, after the Liber novem iudicum); ‘Liber Atharbe Ptholomei de qualitatibus septem planetarum. Solis naturam apud omnes calidam et siccam constat esse…’ (formerly f. 85, after Aomar’s De nativitatibus, see Note below); Capitula Almansoris (formerly f. 97); and Astronomia Ypocratis (formerly f. 99, just before Abraham Avenezra’s De mundo vel seculo).


As noted by Murano (‘Una miscellanea’, 313 and n. 21), the incipit of the Ptolemaic section now missing in the MS (see above) corresponds to Ptolemy, Quadripartitum, tr. Hugo Sanctelliensis (A.2.2), I.4. According to the table of contents f. Iv, this text began on former f. 85 and was followed by the Capitula Almansoris on former f. 97. This range of folia (f. 85-97) would have been enough to contain most of the Quadripartitum opening with ch. I.4.
