When the forces came together for the war, Antony had no fewer than five hundred fighting ships, among which were many vessels of eight and ten banks of oars, arrayed in pompous and festal fashion; he also had one hundred thousand infantry soldiers and twelve thousand horsemen. Of subject kings who fought with him, there were Bocchus the king of Libya, Tarcondemus the king of Upper Cilicia, Archelaüs of Cappadocia, Philadelphus of Paphlagonia, Mithridates of Commagene, and Sadalas of Thrace.
These were with him, while from Pontus Polemon sent an army, and Malchus from Arabia, and Herod the Jew, besides Amyntas the king of Lycaonia and Galatia; the king of the Medes also sent an auxiliary force. Caesar had two hundred and fifty ships of war, eighty thousand infantry, and about as many horsemen as his enemies.
Antony's authority extended over the country from the Euphrates and Armenia to the Ionian sea and Illyria; Caesar's over the country reaching from Illyria to the Western Ocean and from the ocean back to the Tuscan and Sicilian seas. Of Libya, the part extending opposite to Italy, Gaul, and Iberia as far as the pillars of Hercules, belonged to Caesar; the part extending from Cyrene as far as Armenia, to Antony.
