paragraph_text: Relationship with Julius Caesar
  
  Ptolemy XIII arrived at Alexandria at the head of his army, in clear defiance of Caesar's demand that he disband and leave his army before his arrival. Cleopatra initially sent emissaries to Caesar, but upon allegedly hearing that Caesar was inclined to having affairs with royal women, she came to Alexandria to see him personally. Historian Cassius Dio records that she did so without informing her brother, dressed in an attractive manner, and charmed Caesar with her wit. Plutarch provides an entirely different account that alleges she was bound inside a bed sack to be smuggled into the palace to meet Caesar.
  
  When Ptolemy XIII realized that his sister was in the palace consorting directly with Caesar, he attempted to rouse the populace of Alexandria into a riot, but he was arrested by Caesar, who used his oratorical skills to calm the frenzied crowd. Caesar then brought Cleopatra and Ptolemy XIII before the assembly of Alexandria, where Caesar revealed the written will of Ptolemy XII—previously possessed by Pompey—naming Cleopatra and Ptolemy XIII as his joint heirs. Caesar then attempted to arrange for the other two siblings, Arsinoe IV and Ptolemy XIV, to rule together over Cyprus, thus removing potential rival claimants to the Egyptian throne while also appeasing the Ptolemaic subjects still bitter over the loss of Cyprus to the Romans in 58 BC.
  
  Judging that this agreement favored Cleopatra over Ptolemy XIII and that the latter's army of 20,000, including the Gabiniani, could most likely defeat Caesar's army of 4,000 unsupported troops, Potheinos decided to have Achillas lead their forces to Alexandria to attack both Caesar and Cleopatra. After Caesar managed to execute Potheinos, Arsinoe IV joined forces with Achillas and was declared queen, but soon afterward had her tutor Ganymedes kill Achillas and take his position as commander of her army. Ganymedes then tricked Caesar into requesting the presence of the erstwhile captive Ptolemy XIII as a negotiator, only to have him join the army of Arsinoe IV. The resulting siege of the palace, with Caesar and Cleopatra trapped together inside, lasted into the following year of 47 BC.
  
  Sometime between January and March of 47 BC, Caesar's reinforcements arrived, including those led by Mithridates of Pergamon and Antipater the Idumaean. Ptolemy XIII and Arsinoe IV withdrew their forces to the Nile, where Caesar attacked them. Ptolemy XIII tried to flee by boat, but it capsized, and he drowned. Ganymedes may have been killed in the battle. Theodotus was found years later in Asia, by Marcus Junius Brutus, and executed. Arsinoe IV was forcefully paraded in Caesar's triumph in Rome before being exiled to the Temple of Artemis at Ephesus. Cleopatra was conspicuously absent from these events and resided in the palace, most likely because she had been pregnant with Caesar's child since September 48 BC.
  
  Caesar's term as consul had expired at the end of 48 BC. However, Antony, an officer of his, helped to secure Caesar's appointment as dictator lasting for a year, until October 47 BC, providing Caesar with the legal authority to settle the dynastic dispute in Egypt. Wary of repeating the mistake of Cleopatra's sister Berenice IV in having a female monarch as sole ruler, Caesar appointed Cleopatra's 12-year-old brother, Ptolemy XIV, as joint ruler with the 22-year-old Cleopatra in a nominal sibling marriage, but Cleopatra continued living privately with Caesar. The exact date at which Cyprus was returned to her control is not known, although she had a governor there by 42 BC.
  
  Caesar is alleged to have joined Cleopatra for a cruise of the Nile and sightseeing of Egyptian monuments, although this may be a romantic tale reflecting later well-to-do Roman proclivities and not a real historical event. The historian Suetonius provided considerable details about the voyage, including use of Thalamegos, the pleasure barge constructed by Ptolemy IV, which during his reign measured 90 metres (300 ft) in length and 24 metres (80 ft) in height and was complete with dining rooms, state rooms, holy shrines, and promenades along its two decks, resembling a floating villa. Caesar could have had an interest in the Nile cruise owing to his fascination with geography; he was well-read in the works of Eratosthenes and Pytheas, and perhaps wanted to discover the source of the river, but turned back before reaching Ethiopia.
  
  Caesar departed from Egypt around April 47 BC, allegedly to confront Pharnaces II of Pontus, the son of Mithridates VI of Pontus, who was stirring up trouble for Rome in Anatolia. It is possible that Caesar, married to the prominent Roman woman Calpurnia, also wanted to avoid being seen together with Cleopatra when she had their son. He left three legions in Egypt, later increased to four, under the command of the freedman Rufio, to secure Cleopatra's tenuous position, but also perhaps to keep her activities in check.
  
  Caesarion, Cleopatra's alleged child with Caesar, was born 23 June 47 BC and was originally named "Pharaoh Caesar", as preserved on a stele at the Serapeum of Saqqara. Perhaps owing to his still childless marriage with Calpurnia, Caesar remained publicly silent about Caesarion (but perhaps accepted his parentage in private). Cleopatra, on the other hand, made repeated official declarations about Caesarion's parentage, naming Caesar as the father.
  
  Cleopatra and her nominal joint ruler Ptolemy XIV visited Rome sometime in late 46 BC, presumably without Caesarion, and were given lodging in Caesar's villa within the Horti Caesaris. As with their father Ptolemy XII, Caesar awarded both Cleopatra and Ptolemy XIV the legal status of "friend and ally of the Roman people" (Latin: socius et amicus populi Romani), in effect client rulers loyal to Rome. Cleopatra's visitors at Caesar's villa across the Tiber included the senator Cicero, who found her arrogant. Sosigenes of Alexandria, one of the members of Cleopatra's court, aided Caesar in the calculations for the new Julian calendar, put into effect 1 January 45 BC. The Temple of Venus Genetrix, established in the Forum of Caesar on 25 September 46 BC, contained a golden statue of Cleopatra (which stood there at least until the 3rd century AD), associating the mother of Caesar's child directly with the goddess Venus, mother of the Romans. The statue also subtly linked the Egyptian goddess Isis with the Roman religion.
  
  Cleopatra's presence in Rome most likely had an effect on the events at the Lupercalia festival a month before Caesar's assassination. Antony attempted to place a royal diadem on Caesar's head, but the latter refused in what was most likely a staged performance, perhaps to gauge the Roman public's mood about accepting Hellenistic-style kingship. Cicero, who was present at the festival, mockingly asked where the diadem came from, an obvious reference to the Ptolemaic queen whom he abhorred. Caesar was assassinated on the Ides of March (15 March 44 BC), but Cleopatra stayed in Rome until about mid-April, in the vain hope of having Caesarion recognized as Caesar's heir. However, Caesar's will named his grandnephew Octavian as the primary heir, and Octavian arrived in Italy around the same time Cleopatra decided to depart for Egypt. A few months later, Cleopatra had Ptolemy XIV killed by poisoning, elevating her son Caesarion as her co-ruler.
