`_`	(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).

Vatican, Biblioteca Apostolica Vaticana, Barb. lat. 182

Date:

s. XV (perhaps ‘1452’, written in the top margin of f. 1r, but this need not be a date; added horoscope for 17 July 1456 on f. 1v – the date is noted in the central panel and the horoscope was cast for one 17 July (Sun at 2° Leo), but the other planetary positions are wrong for 1456 and do not lead to any other recognisable date).

Or.:

northern Italy, probably Florence.

Prov.:

Filippo di Cenni d’Aiuto, professor of medicine at the University of Florence (cf. f. 2vb: ‘Magistri Filippi Cennii de Florentis’); Carlo Strozzi (d. 1671), cf. f. 3r: ‘Caroli Strozzae Thomae filii 1635’; Cardinal Francesco Barberini (1597-1679).

Paper and parchment, 138 f. The MS originally consisted of five texts copied by a neat hand (f. 3r-99r, 103r-124r, 125r-133ra), with painted initial on f. 3r. Later on, a second, rather careless, hand glossed the MS and added numerous texts and notes in the margins of f. 103r-110v and 132r-133r, and on pages which had been left blank (f. 1r-2v, 99v-102v, 124v, 133v-139r). It cannot be ruled out, however, that both hands belong to one and the same scribe, for both sign in a similar fashion, e.g. ‘Omnipotenti gratiarum actiones referendo’ (first hand, f. 99rb) and ‘Deo omnipotenti gratias’ (second hand, f. 100rb).

Astronomy and astrology: the five original texts included Ptolemaica (3ra-99rb); Campanus of Novara, Theorica planetarum (103ra-119va); Theorica planetarum Gerardi (119va-124rb); Haly Embrani, De electionibus horarum (125ra-132ra); and Gergis, De significatione septem planetarum in domibus (132rb-133ra). The added texts and notes include, among others, a set of sortes at least partly related to the Prognostica Socratis Basilei (1ra-2v); excerpts from Thebit Bencora’s De imaginibus (99va-99vb) and of Pseudo-Albertus Magnus’s Speculum astronomie (100va-101rb); Ptolemaica (101rb-101vb); excerpts from Alcabitius’s Introductorius (102ra-102vb); Alkindi (?), Saturnus in Ariete sub radiis… (132rb-133rb); Astronomia Ypocratis (133rb-133vb); Albumasar, Flores (136rb-137rb); Capitula Almansoris (137va-138rb); and Zael, Quinquaginta precepta (138rb-138va).
