Apparantly Isis, The One Above Fate, had other plans for Cleopatra. While Rome was more likely to support her brother than her, a mighty advocate came forward, Julius Caeser. His aid to Cleopatra is generally attributed to her great beauty and powers of persuasion, it may well have been her role as High Priestess of Isis which inclined Julius Caeser to support her claim.
Rome at the time was violently opposed to any foreign worship. Julius Caeser however, exhibited a curious tolerance toward any foreign faith. Though he acted to supress foreign guilds, believing that they were a threat to the stability to the government, he left the Isian (worship of Isis) practice alone.
How Cleopatra and Ceaser first met, their first encounter may have been orchestrared by the Isian Clergy, who recognized in the devout Cleopatra and the powerful general a chance for a royal union on the scale of the divine Isis and Osiris. On a more practival level, their union would end the tearing down of temples and shrines to Isis by the Roman authorities.
Despite the setbacks of later events this is the scenario that unfolded. Although Julius was murdered by the treachery by those he trusted, in a curious parallel with the death of Osiris, the faith of Isis continued unchecked.
When Cleopatra recreated her divine union with Julius Caeser by allying herself with his friend and "heir" Marcus Antonius, she was again transferring the power of Egypt to another Roman known to have sympathy for the religon of Isis, who could be counted on not to interfere with the growth of that worship.
Although Cleopatra was physically defeated by the coward Octavius (known to get 'sick' before battles and never fought with his men and Marc Antony and Ceaser did) she was not spiritually. She was attacked at for loving two Romans, but the faith she was dedicated to flourished for centuries to come after her death.
