Compendium astrologicum. Libri V et VI., 2 Bde.. Libri V et VI.

Rhetorios 'the Egyptian' was the last astrological expert to write in Greek before the Arab conquest of Egypt. His Compendium , written about AD 620, is of central importance, preserving as it does a great deal of older material which is otherwise lost, and new epitomes of it were repeatedly written by later Byzantine authors. Pingree's edition is the first time that the Greek text has been made fully accessible in the version of the most important evidence, cod. Paris. Gr. 2425.
