For further information, see Southern (2014, p. 185) and Roller (2010, p. 151). ↑ Jones (2006, p. 60) offers speculation that the author of De Bello Alexandrino, written in Latin prose sometime between 46–43 BC, was a certain Aulus Hirtius, a military officer serving under Caesar. ↑ Burstein (2004, p. 30) writes that Virgil, in his Aeneid, described the Battle of Actium against Cleopatra "as a clash of civilizations in which Octavian and the Roman gods preserved Italy from conquest by Cleopatra and the barbaric animal-headed gods of Egypt." ↑ For further information and extracts of Strabo's account of Cleopatra in his Geographica see Jones (2006, pp. 28–30). ↑ As explained by Chauveau (2000, pp. 2–3), this source material from Egypt dated to the reign of Cleopatra includes about 50 papyri documents in Ancient Greek, mostly from the city of Heracleopolis, and only a few papyri from Faiyum, written in the Demotic Egyptian language.
