Work A.4

Ptolemy
Phaseis

Content Two books on the heliacal risings and settings of the fixed stars and their meaning in meteorology.

Origin Greek (Φάσεις ἀπλανῶν ἀστέρων καὶ συναγωγὴ ἐπισημασιῶν, ‘Appearances of Fixed Stars and Collection of Prognostics’). Book II only is extant in Greek. Fragments of both books survive in Arabic (see Neugebauer, Samsό/Rodríguez, Samsό, Morelon). The main part of Book II (the parapegma) was translated into Latin in the 16th and 17th c.
