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.

Cesena, Biblioteca Comunale Malatestiana, Plut. S.XXVII.3

s. XIII2 (the core of the MS, including the second Ptolemaic section, was probably copied in or shortly after 1263, date mentioned by the scribe in a gloss (f. 36rb) and denoting presumably the present year; another gloss by the scribe or the contemporary glossator refers to events that occurred in 1267 and 1270, see below), with 14th- and 15th c. additions f. 111vb-114v (including the third Ptolemaic section).


Italian hands. The scribe or the contemporary glossator mentions (f. 76va) a total solar eclipse in Sicily and Calabria, which he himself saw, and the calamities that followed in those regions, including the King of France’s disastrous expedition to Carthage through Sicily. These events correspond to the solar eclipse of 25 May 1267 and to Louis IX’s Eighth Crusade to Tunis in 1270 (see also Lemay, 70-72).
