" Antony was so captivated by her, that while Fulvia his wife maintained his quarrels in Rome against Caesar by actual force of arms, and the Parthian troops...were assembled in Mesopotamia, and ready to enter Syria, he could yet suffer himself to be carried away by her to Alexandria, there to keep holiday, like a boy, in play and diversion, squandering and fooling away in enjoyment that most costly, as Antiphon says, of all valuables, time." - Plutarch
The novel also emphasizes the financial "rape" of the east by Cassius during the civil war following Caesar's assassination. The sheer lack of resources in the traditional centers of the East is portrayed as the reason Antony turned to Cleopatra in the first place to fund his Parthian campaign.
Antony initially, at the urging of one of his advisors, charges Cleopatra with providing aid to the conspirators when she sent four legions from Alexandria to the governor of Syria who subsequently diverted them to Cassius. Cleopatra points out that Egypt was suffering from plague and famine at the time so she was only too glad to comply with the request of Sextus, the legitimate Roman governor of Syria to remove the burden of feeding the legions from Egypt's dwindling grain supply. According to Cassius Dio, Sextus was actually a relative of Caesar so Cleopatra would not have viewed granting a request by him as accommodating Caesar's assassins.
"The governor of Syria was Sextus; for since he was not only quaestor but also a relative of Caesar's, Caesar had placed in his charge all the Roman interests in that quarter, having done this on the occasion of his march from Egypt against Pharnaces." - Cassius Dio
Cleopatra in turn pointed out that it was also not her fault that the fleet she sent in support of Antony and Octavian was destroyed in a storm at sea.
I find these complex exchanges during and following the civil war with the conspirators most interesting. If you read book 47 of Cassius Dio's history of the period, you discover that there were various Romans from both sides of the controversy running around in the east claiming to be provincial governors and engaging in battles to assert their claims and issuing edicts to squeeze money from eastern populations.
"...learning that Caesar [Octavian] was growing stronger, they [Brutus and Cassius] neglected Crete and Bithynia, whither they were being sent, since they saw no prospect of any noteworthy aid in those countries; but they turned to Syria and to Macedonia, although these provinces did not belong to them at all, because they excelled as strategical positions and in point of money and troops. 2 Cassius went to Syria, because its people were acquainted with him and friendly as a result of his campaign with Crassus, while Brutus proceeded to unite Greece and Macedonia. For the inhabitants of those districts were inclined to give heed to him in any case because of the glory of his deeds and in the expectation of similar service to their country, and particularly because he had acquired numerous soldiers, some of them survivors of the battle of Pharsalus, who were even then still wandering about in that region..."
"...He [Brutus] reached Macedonia at the moment when Gaius Antonius had just arrived and Quintus Hortensius, who was his predecessor in the governorship, was about to retire; however, he experienced no trouble. For Hortensius embraced his cause at once, and Antonius was weak, being hindered during Caesar's supremacy in Rome from performing half of the duties belonging to his office. Vatinius, who was governor of Illyricum near by, came from there to Dyrrachium, seized it before Brutus could prevent it, and acted as an enemy in the present strife, but could not injure him at all; for his soldiers, who disliked him and furthermore despised him by reason of a disease, went over to the other side. So Brutus, taking over these troops, led an expedition against Antonius, who was in Apollonia; and when Antonius came out to meet him, Brutus won over his soldiers, shut him up within the walls when he fled thither before him, and captured him alive through betrayal, but did him no harm. After this success, Brutus next acquired all Macedonia and Epirus, and then despatched a letter to the senate, stating what he had accomplished and placing at its disposal himself as well as the provinces and the soldiers. The senators, who, as it chanced, already felt suspicious of Caesar [Octavian], praised him[Brutus] highly and bade him be governor of all that region..."
