_ (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.

Work C.3.17

Albertus de Brudzewo (?)
Circulum pro exitu geniture ab utero iuxta verbum Ptolomei 51 rectificare

A commentary on Centiloquium v. 51, dealing with the rectification of nativities. The extant manuscripts suggest that this text originated at the University of Cracow in the 1480s (and certainly before 1488, when most of MS Vatican, BAV, Pal. lat. 1439 was copied). Rosińska (with a query) and Markowski ascribe it, very plausibly, to Albertus de Brudzewo, who was professor of astronomy and astrology at the University of Cracow in the 1480s and 1490s. In most copies, the text stands alone among various astrological material, but in four of them, it is part of a larger text. In MSS Cracow, BJ, 1856, and Karlsruhe, BLB, Rastatt 36 (f. 85r-85v), it forms most of the first canon of a treatise on the interpretation of nativities in 21 canones, which is one of the several versions of a Tractatus de scientia nativitatum commonly taught at the University of Cracow in the late fifteenth century and sometimes associated to Martin Bylica de Olkusz or to one Simon, perhaps Simon of Sierpc (on this treatise, see Rosińska, 1909-1910, and Markowski, 117 and 189). In MSS Basel, UB, O.III.31, and Paris, BnF, n.a.l. 208, it occurs as the opening chapter of a treatise on the establishment of nativities, most of whose material derives from the Canones concernentes nativitatem nati, a text written as an appendix to Albertus de Brudzewo’s judgement on a nativity of 6 April 1445, probably by Albertus himself or under his supervision (see MSS Paris, BnF, lat. 7350, f. 99r-135v; and Vatican, BAV, Pal. lat. 1439, f. 41r-66r, also Rosińska, 502, and Markowski, 103 – Markowski attributes it to Johannes Virdung of Hassfurt). In the Basel MS, this treatise bears the title ‘Liber continens canonem magistri Alberti de Pruzaff [Brudzewo] super nativitates et iudicia, coll<e>ctium (!) in universitate Cracoviensi’. To these copies one should add the lost MS St Petersburg, Biblioteka Gosudarstwiennaja Publicznaja im. M. J. Sałtykowa-Szczedrina (now Rossijskaja Nacionalnaja Biblioteka), Lat. F.XVII.74, s. XV, where our text occurs on f. 127r (‘De genitura. Circulum pro exitu geniture…’), apparently as part of a longer treatise (f. 104r-136r) entitled ‘De nativitate hominis liber quem dominus Albertus Brosevo, magister Cracovensis, operose collegit et fideliter’ (on this manuscript, which was part of the Załuski collection, transferred back to Warsaw after the Revolution in 1922 and bombed in WWII, see L. Birkenmajer, Stromata Copernicana, Kraków, 1924, 101-103; Markowski, 9 and 314; and The Inventory of Manuscripts from the Załuski Library in the Imperial Public Library, eds O. N. Bleskina, N. A. Elagina, Warszawa, 2013, 136 (no. 696)). The genesis and affiliation of this text require more research.
