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.

‘D<omini> Ioannis Gregorii filii …ur (?) Ioannis Antonii Leverati (?) Genuensis [Genoa]’ (f. 1r, 16th-c. hand); ‘Clarissimo arcium et medicinae doctori d<omino> m<agistro> Iohanni ex Rubeis maiori suo observan<dissimo?>. Genuae [Genoa]’ (f. 144v, late-15th or 16th-c. hand). A Johannes de Rubeis of Parma was physician to Jean sans Peur, Duke of Burgundy, and author of annual prognostications, two of which are extant for the years 1420 and 1421, but the note is probably too late to apply to him.
