Julia Balbilla (Greek: Ἰουλία Βαλβίλλα, AD 72 – after AD 130) was a Roman noble woman and poet. Whilst in Thebes, touring Egypt as part of the imperial court of Hadrian, she inscribed three epigrams which have survived. Family and early life Balbilla's family were well-connected members of the royal family of the Kingdom of Commagene, a principality in what is now Turkey which was annexed by the Roman Empire. As well as Egyptian and Greek elements, Balbilla's ancestry included Armenian, Median, Syrian and Seleucian lines. Balbilla was the second child of Gaius Julius Archelaus Antiochus Epiphanes and Claudia Capitolina, a Greek woman born in Alexandria. Her older brother was Gaius Julius Antiochus Epiphanes Philopappos, one of the first men of eastern descent to become consul at Rome. Balbilla's parents were distant cousins. Claudia Capitolina's paternal grandmother was Aka II of Commagene, the great-granddaughter of Antiochus I Theos of Commagene. Balbilla's father, was the first born child of Antiochus IV of Commagene and Julia Iotapa of Commagene. Both Antiochus IV and Iotapa were descendants of Antiochus I Theos. Balbilla's maternal grandfather, after whom she was named, was Tiberius Claudius Balbilus, a Greek of Egyptian descent. He was an astrologer and a learned scholar. He became one of the highest ranking magistrates of the Equestrian order and was Prefect of Egypt from AD 55 to 59. Balbilus and his father, Thrasyllus of Mendes (Tiberius Claudius Thrasyllus), a grammarian and astrologer were friends of the first Roman emperors including Tiberius, Claudius and Vespasian. Balbilla's paternal grandparents, Antiochus IV of Commagene and Queen Julia Iotapa were puppet rulers under Rome. Balbilla was born and raised in Rome in the household of her paternal grandfather, Antiochus IV. Prior to Balbilla's birth, Vespasian had ordered Antiochus IV to abdicate the throne of Commagene because of his alleged disloyalty to Rome. Antiochus IV and his brother, Callinicus, were accused of colluding with the Kingdom of Parthia against Rome. It is unknown whether these accusations were true. Vespasian gave Antiochus IV sufficient revenue for a luxurious life in Rome. This afforded Balbilla and her brother a traditional Greek education. The family later moved to Athens where Balbilla's father, Epiphanes, died at 92 years of age of unknown causes. Capitolina then returned to Alexandria where she married Marcus Junius Rufus, a Roman politician. Capitolina spent her remaining years in Alexandria. Balbilla lived with her for a time then
