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.

Work A.4

Ptolemy
Phaseis

The Phaseis or Phases of the Fixed Stars (Greek: Φάσεις ἀπλανῶν ἀστέρων καὶ συναγωγὴ ἐπισημασιῶν, ‘Appearances of Fixed Stars and Collection of Prognostics’) consists of two books dealing with the heliacal risings and settings of the fixed stars and their influence on the weather. Only Book II survives in Greek and it is from this defective Greek version that the two sixteenth- and seventeenth-century Latin translations were made. Fragments of both books survive in Arabic.
