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.

s. XIV.




the MS belonged to a bishop of Vaison-la-Romaine and appears to have been in northern Italy by the end of the 14th c., for f. 54v contains the fragment of an act issued by Cardinal Francesco Renzio (d. 1390) concerning taxes in Florence. The MS later belonged to the Florentine Dominican Benedetto Pagagnotti (d. 1523) and to ‘three brothers Tramezini’, who gave it to the bishop of Viterbo Giampietro Grassi (d. 1538), whose library was bought by cardinal Alessandro Farnese. The history of the MS is detailed by notes in three different hands on f. Ir: ‘Hic liber est r<everen>di domini episcopi Vasienensis’, ‘Domini Benedicti de Pagagnottis de Florentia ordinis Predicatorum’ and ‘Post hoc Tramezini fratres Bibliopolae Romae donarunt Jo. Crasso episcopo Viterbiensi’ (Ir).

‘Geber super Almagestum Ptholomei. Cum practica geometriae [title added in upper margin, apparently by another hand]. <S>cientia species habet quarum melior post scientiam sunt digniores ut evanescant et destruantur. Completa est declaratio eius. Completus est tractatus nonus, et est ultimus liber. Hunc librum transtulit in Toleto magister Giradus (!) Cremonensis de Arabico in Latinum.’
