_ (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.

Italy or Spain for f. 1-88; f. 89-188 were intended for the use of an astrologer in Spain (cf. astronomical tables for Seville, Toledo and Valladolid f. 116v-117r and for Toledo, Valladolid, Seville, Cordoba and Murcia f. 118v-125r; ascension tables for latitudes 30°-45° f. 125r-132r; tables of houses for Toledo and Valladolid f. 132v-138r; tables of houses also for Florence f. 138v-139r). This astrologer may well be Alfonsus Dyonisii of Lisbon (d. 1352, on him see C.2.2, Note 3), for the MS also preserves the only known copy of an astrological text on the rectification of nativities translated by him in Seville in 1334 (f. 180r, only the last page survives due to missing folia). In the colophon (ed. Thorndike, 136-137), Alfonsus presents himself as physician to King Alfonso IV of Portugal (reigned 1325-1357) and to his daughter, Maria, queen of Castile and León, i.e. Maria of Portugal (1313-1357), who married King Alfonso XI of Castile in 1328. In the same colophon, Alfonsus also mentions his own astronomical tables for the meridian of ‘Succa’, which, as Thorndike suggested, might be a mistake for Lucca. This suggestion is all the more plausible, because the above-mentioned tables of houses for Florence f. 138v-139r are attributed to one ‘master Al.’, whom it is tempting to identify with Alfonsus. Lucca is just 60 km west of Florence and at the same latitude, so that the tables of houses would be valid for both cities.

Parchment, III+188+IVa f., MS made of two parts, the first of which (f. 1-88, decorated initials) is copied in a very neat hand. The second part (f. 89-187) was copied by at least two hands. One or several folia are missing between f. 179 and 180.

‘De creticis diebus in continuis febribus et acutis iuxta Ptolomeum secundum quod Lune status invenerit certificemus. Ad quod oportet scire Lunam in zodiaco 8 proportiones habere. Prima et principalis est existentia gradus in quo cum Sole est, et dicitur coniunctio — quod si eundo obviat malignis vel fixis que dicuntur puthei sentiet eger passionis detrimentum.’
