贝勒尼基她喜好时尚、宴会和珠宝。她性格懒散，且对人凶恶，尤其是对待农民、奴隶、或低下阶层的人们时，这使得她不是个好的统治者。她只会说她的母语希腊语，她教育程度不高，因为她缺乏学习的精神。虽然有这些缺点，她对她的家族和朋友相当仁慈且富关爱，另外她非常漂亮。

Berenice IV Epiphaneia (Greek: Βερενίκη; 77–55 BC) born and died in Alexandria, Egypt. She was a Greek Princess of the Ptolemaic dynasty. Berenice was the daughter of Ptolemy XII Auletes and probably Cleopatra V Tryphaena, sister of the famous Cleopatra VII (lover of Roman Triumvirs Julius Caesar and Mark Antony), Arsinoe IV, Ptolemy XIII and Ptolemy XIV. In 58 BC, Ptolemy XII and Cleopatra VII fled to Rome in search of political and military aid against Berenice's elder sister Cleopatra VI Tryphaena, who had become far too powerful. After Tryphaena's death in 57 BC, possibly poisoned on behalf of Berenice, she at age 20 became the sole ruler of Egypt due to her father's absence, and with him and Cleopatra absent she had no worry about being overthrown or overpowered and executed.
